When the CHIPS are down

[EF MAX]

1.4Tdi,, got mine chipped today by Impossible Performance in Kent.. www.impossible-performance.cwc.net

I decided to have my car tested on a rolling road first and afterwards and not by the chipping company,, this allowed me a degree of honesty in the results.

Before chipping: 81BHP and 198Nm. With cruise control set to 2750rpm in 5th gear on the motorway on a level stretch of the motorway, DIS reads 46.7mpg.

After chipping, same technician, same rolling road: 112BHP and 258Nm. With cruise control set to 2750rpm in 5th gear on the motorway on a level stretch of the motorway, DIS reads 48.9mpg.

So how does it look,, well first off the chip is in one of the many compartments hidden under the passenger front seat.. The chip itself is no different than the one that comes out,, which you are allowed to keep. It would take a very sharp and extremely keen eyed Audi Technician to notice the difference visually,, and there is no reason for him to be looking there in the first place..

Previously my new Tdi would prefer to be in the 2000rpm – 4000rpm range for any action to take place. In slow moving traffic it preferred not to be left in 5th gear at revs below 2000rpm and if you did it was not comfortable. This meant for many gear changes which for a guy who has just come from an automatic V6, is a pain.

When it comes to action the standard Tdi comes alive at about 2500rpm and is not happy above 4000rpm.

WELL NOW,, things are different, very different. The car pulls from 1500rpm in any gear and it pulls strong from 2000rpm and by time you get to 2500rpm,, watch out this baby is coming through like a train about to discover sex for the first time.

There are no flat spots in the rev range and you have to watch how you pull off in 1st and 2nd gear as the sheer quantity of torque will have the steering wheel fighting in your hands.

Customer service from this company was 1st class and very professional.
So am I a happy bunny,, ummm, I think so… and all for a wisely spent £295inc.

[Stuart_D]

EF - That sounds great!!
I'm going to get mine done when the warranty runs out this October.

This sounds absolutely brilliant... I read it and thought this must have been one of those £1000 jobs... BUT just under £300!!! I don't want to wait until the warranty expires!!! I want it now!!!

So how much did you have to pay for the before and after independent rolling tests?

Hmmm... thinking... thinking...

The before and after rolling road test was a favour called in.. I am not too sure how much they charge but I did my mate a favour a while back and this was pay back..

Check out http://www.jabbasporta.co.uk, they offer a chip upgrade with
a before and after rolling road print out for £360.

They also map the chip to your requirements, ie. making the power come in more progressively and linear and can also change the characterisitcs of the fly by wire throttle.. Another important
point is that they map the chip to stay within the emissions required
so you wont get loads of black smoke comming out of the back.

Had my last car chipped there and can highly reccomend them.

thanks guys... is all starting to sound really tempting... and all this becuase mr audi gave ma a 130bhp diesel A3 Sport as a courtesy car... hehehe

I'm very tempted also I must admit. But I can't make my mind up which one !

2002 TDI SE - Silver - Open Sky System

[Johann]

I like the idea of their future one that will be switchable and thus (hopefully) undetectable by the dealer... But that will be even MORE than the £350 option surely...

They can also mail order send you the chip! BUT they want to keep your old chip... so you can't ever swap it back yourself by the seems of it... BUT in offering this service it surely must mean that it is not too difficult to get to the chip in the first place...

EF MAX's original post stated that he kept the old chip... thus my reasoning is that you should surely then be able to take out the new chip and replace with the old one before you take it in for a service? EF: is it a complicated thing to remove and replace?

I'm not too worried by having before and after tests as by the sounds of it you will definitely notice it anyway... so whether it was 20% or just 15%, does it really matter?

[RTV]

When I had my last car chipped at Jabbasport they gave the original chip back in a tiny case. They also took an electronic copy in case I ever lost it and would charge just £15 for another copy.

With regards to switchable chips there are a few copanies already offering this. You can switch between chip programs from the cruise control stalk. There are also some copanies offering the ability to flash the chip rather than replcae it making it totally undetectable. They even offer you a free 1hour trial, they flash your chip and then 1 hour later it reverts back to your origial program, cleve stuff !

These features are normally at least twice the price of the chips mentioned in this thread.

The chips are no different than any other EPROM that are found on a basic computer motherboard,, but they are delicate and the pins are easily bent if not careful.

I did not watch my technician do his business as I had my mum with me and she wanted to go "shopping".

That said, on my last car, that was chipped at Van Aaken Developments I did watch them take the chips out and replacing it just requires a steady hand and a degree of coolness.

The real work is in the reprogramming and with the appropiate software it becomes no more difficult, with the right knowledge, than that of re-chipping a mobile phone.

Once again, the performance gain is just amazing.

Now if the Tdi had a 6th gear this car would take off on the motorway. Last weekend I took the car off road and private and hit a flat out 115mph. It gets to 60 double quick, around 8ish seconds and it zips up to 100 pretty quick too. From 100 to 115 takes a little longer.

I also went for a drive in a new 1.6FSI,, basically there is no comparison AT ALL. Not even close.. the chipped TDi pins you in your seat in the first three gears and sets of the traction control if you pull off to hard.

[Johann]

YUM!!! I love the sound of that... mine went in again this morning to check the ongoing cigarette lighter debacle... so was dropped back in office again by a 130bhp A3 TDI Sport (same as the courtesy car I had) what a wonderful shove that car has... it just pins you in your seat and that is what I want... so this chip sounds cool...

BTW will your car still go through its MOT on this chip?

No problem there either,, a CO2 reading has suggested that the emissions are about 2% lower than the factory standard one,, not a bad deal ahh.

Hi,

Is it possible to chip a 1.6 FSI? If so has anyone had it done?

It is possible, but the rewards from chipping a TDi are greater and much easier to see where your money has gone.

With a petrol engine, more convential tuning, ie air in and air out ideas might work better.

Maybe the next thing to buy might be an EPROM programmer/copier. :D :D :D

[ianjohnsonws14]

Just a brief warning to observe ESD precautions when handling the chips - store in a ESD bag (from Maplins) and do not handle them unless you are earthed (mains plug with one wire connected to EARTH pin works fine). Failure to do this can wreck the chip.

There are at least 2 continental companies doing "petrol 1.4" chips, (links on A2OC) but sadly I've not yet found one in the UK either.
Some UK companies do the VW 1.4 in Polo form, but not specifically the A2. about +8bhp is claimed for Polo.

However the German firm of WES (formerly AH tuning) claim 90bhp which is +15bhp(+20%).
Cost is €450 + €80 fitting + €190 guarantee.
see http://www.wes-chip-tuning.de/wes/modell/audi/audi29.html

Although tempted I can't justify the expense of driving to Germany, although they will post it and you can fit it yourself.

I'm a little cautious about how much extra torque the 1.4 16V gearbox will handle on the A2 as its uniquely made of magnesium, unlike the Polo, or A2 TDI. WES offer a guarantee on their installations (extra cost), so I guess they think +20% power & torque is OK.

[jon.od]

Hello every one this will be my inogoral post. Am Picking up a new A2 TDI Sport in the next week and am looking forward to it, I had to sell my Mini Cooper S as i am now doing enterprise Mileage so more power and increased economy sounds right up my street.

How many of us are looking at the impossible performance chip as they are no more than 10 minutes away from me, would it be worth me finding out about a group discount?

[Keith]

UK 1.4 Petrol chips:

Still nothing to announce yet!

I did approach AmD, http://www.auto-amd.co.uk/ as it was suggested on a posting in January 2003 that they were in development of one, but when asked, received the following reply back:

"We are in development, but due to a higher volume demand the product is taking a backseat at the moment".


Which I assume to mean "we've put it on our 'things to do list' but business isnt slack enough yet to warrant spending any time on low-sales items"

Shame.

[tikki]

Made an appointment to have our 8000 mile 1.4TDI superchipped on Thursday (the day we get the car!).

Tried to arrange insurance through Superchip's recommended insurers and were quite happy with the premium of £398 BUT.......
They insist on uprated brakes and an engineers report to confirm it has been done!!
I suppose that increasing the 75 BHP by 40% probably does need better brakes????[21]

Anyway, have decided not go go ahead with the chip but will probably make do with an extra 15 BHP from a plug in 'Box'

Anyone any experience of a plug in box?:(

A2 1.4TDI SE - SOON !!
A4 1.9TDI SE 137BHP Cream Leather

The brakes on the 1.4tdi might not be disc at the rear but they still do a very good job.

Options for uprating the front bakes are limited to better vent disc and or pads,, not sure what is available for the back wheels. Would be interested to see what you come up with..

[tikki]

Picked up our first A2 today (Ex-Demo) and half an hour later had it in at a Superchip installer. The installer had contacted Superchips recommended insurer to see what was needed to upgrade the brakes.

It turns out that they only wanted better pads which cost around £45 on top of the chipping. The Superchip installers also provided the engineers report.

Performance is great, no sudden surges as on our A4 TDI, just smooth power right throughout the rev range.........Mind You, i haven't really got anything to compare it with because I only did about 3 miles before having it chipped :D :D :D

Cheers Stuart I think i might give them a call later on today

[Tim]

These mods all sound great, although I must be honest and say I've lost track of who's fitting which chip now. Is EF's original chip still the one to go for. Also, now some of you have had it fitted for some time, has anyone got some final comments on how it has effected the econony under normal driving conditions as opposed to on a rolling road.
I still doubt that this is going to go like my Chipped S3 or my A8 4.2, but hey, I'm willing to give it a try.

[Simmo]

Just got my A2 done today from CCCTech in Sheffield. We used Vag-com to measure before and after torque. Before was 238Nm at 2240rpm. After was 358Nm. The chip is the same as EFMAX i think as the two companies are agents for the same company.

This is the 2nd time ive used him as i have had a a 2.5v6tdi chipped by him also. Service is A1!!

As for the A2 - all i can say is that the performance improvement is breathtaking - literally!

Sim

[Tim]

I would appreciate Simmo if you would let us know how this effects the economy and also if it's not nosey, how much was it. Are these people marketing as using Superchips or another brand. Thanks.

[Simmo]

Economy seems no different. I dont have DIS - so have to go on the crude method of miles between fill-ups. The cost is circa £300. Its not a superchip product either. Your best bet for further info would be contact Simon at CCCTech.

[Tim]

Thanks Simmo, will do

[EF MAX]

SIMMO,, I have now done 5000 miles in mine.

The performance is still amazing, especially between 2000rpm and 4000rpm,, any gear, it just takes off.

Fuel wise,, if I drive it around town all week with loads of stop start and general traffic stuff I will get about 350 miles between pit stops.

That is from a full tank to the DIS reading 0 miles to go.. this is 35litres as the car reserves 7Litres which is hidden from the DIS calculations [about 70miles beyond the Zero reading if you are feeling lucky],, so this equals 55mpg.

If I stick to the motorway and stay at a steady 70mph, under the above pit stop rules I get an average of 450miles,, so this equals 70mpg.

If I enjoy the CHIP by driving hard when ever I feel like it,, taking it into the red line etc and holding on to naughty motorway speeds [just to pee other Audi's off,, TT's etc] then I will get around 400miles per pit stop.. that is still over 60mpg.

I did a 400mile round trip this weekend, mainly night driving,, this was two up with luggage, my camera equipment and the addition of 110kg of audio equipment,, mixture of M/Way and A-roads. It took me about 2 hours 30mins each way and even allowing for slow moving traffic my DIS says I still have 46miles to go and the fuel indicator/ping hasn't come on yet.

The car is just as quiet as before, there appears to be no issues that I am aware off and I am still smiling behind my tinted windows like a little boy who has just discovered girls.

Does anybody know if the "mild" ABT chip for the 1.4TDi (95bhp) is a valid Audi upgrade and subsequently does not effect the UK warranty? Audi UK say they THINK it does invalidate it but they are checking to make sure. I understand from other posts on the forum that its OK on the continent? Has anybody had this confirmed in the UK?

If that IS the case, I wonder what kind of warranty Heritage Audi of Salisbury are offering on their 100hp 1.4 TDI Sport (100hp)

I WAS tempted to have a look at this car but decided the price was way too high!!
If you use www.audiukusedcar.co.uk and do a search for a 1.4 tdi sport, one of the search results will bring up this car.

Alternatively, here is a direct link which brings up text details only. http://www.audiukusedcar.co.uk/scrolingspec.asp?now=09%2F07%2F200322%3A41%3A13

The car itself is obviously under warranty - are the dealers going to honour the manufacturers warranty or not?

Wish I'd asked before buying elsewhere!!

[Tim]

Don't want anyone to be dishonest or anything, however the fact is, if you don't make a big point out of telling your dealer about the chip, they won't generally worry. Even though when they drive it they will realise.
It is easier for them to make money from Audi getting warranty payments than it is for them to tell you that it isn't covered anymore, get into an argument and then lose you as a customer to another cheaper no franchised service agent of which there are plenty of competent ones around.
Like us, dealers want the easiest way out and so warranty payments from Audi will do just fine thanks.
Unless you drive your chipped A2 like a race car (in which case you've bought the wrong thing anyway) the extra strain that you are putting on the components when you are using the extra power will be minimal. The liklyhood of this manifesting in ANY huge repair bills is very slim.If it does happen you may have to ask yourself if the fact is it probably would have happened anyway.
Don't worry, just enjoy your extra performance when you do occasionally dip into it.
Cheers all.

[Simmo]

Further to Tims post - probably unlikely that they would know it was chipped even if they drove it. They would have to drive it harder than i would like anyone to drive a car of mine (other than myself on occassions) to notice any real difference. They would then have a hard time confronting you if they had ragged the engine somewhat.

Chipping is undetectable generally - especially on the TDI's as there is generally no increase in turbo noise, wastegate, dump valve groans etc that you can get with some petrol turbo chips. The only real way to find out would be for them to locate and extract the ECU, open it up and look inside - quite some hassle really.

I have a A4TDI in addition to an A2TDI - both chipped and I just take them to the dealer for servicing/warranty work without putting the original chip in, even if they are going near the ECU. Truth is, the mechanics probably dont give a S$$$t anyway - they want to service, repair your car with minimum fuss, move on to the next one, go home and have a cup of tea etc.

[jon.od]

One of the best things about living in blighty is the afformentioned work ethic. Do as little as possible! I.e don`t go and create extra work for yourself

[jon.od]

The decision has been made and the appointment booked the car is in for a little bit of neuro-surgery on the morrow. Should come back with a little more attitude.

[Mal]

As chipping seems a no-go for the 1.4 petrol......has anyone tried other methods,to improve performance(Air-filters.spark plugs..etc.)??

Also, apparently the latest Skoda Fabia uses the same engine as the A2 and Polo,but develops 100 bhp,instead of the 75 bhp of the A2 and Polo......does anyone know what changes the Fabia engine has over the 75 bhp engine,and if the A2 engine can be modified to the 100 bhp specification.

[Ricardo]

The simple reason why the TDi's "chip" and the petrol dosn't is the T i.e. the Turbo Charger. The chips increase the maximum boost pressure (bit more complicated than that but essentially thats where the extra performance comes from).

The only way to re-chip and power boost a normally aspirated engine is to alter the ignition timing and fuelling which can give you 5% or so but usually effects emissions and/or drivability.

I doubt very much if the Skoda engine is "the same" as the Polo etc a 30% power increase in a normally aspiratedm engine means serious modifications - camshafts, exhaust and possibly pistons and conrods.

I dont know if anybody does one but Supercharging a petrol A2 would be fun [27]

Ricardo

[Ricardo]

Just checked there are 2 1.4 petrol engines in the Fabia 68PS 8 Valve and 100PS 16 Valve - the A2 1.4 is 75PS (& I think 8-valve). I believe the 100PS is the Audi FSI unit which is 16v and not available in an A2 in the UK. So if I am right it sounds like the A2 1.4 is already "chipped" compared the Fabia's - sorry.

Ricardo

[shezlee]

The A2 TDI is a 6 valve (3 cylinders - one inlet and one exhaust per cylinder) and is 75bhp. Some members of the A2OC have had their A2 TDI's chipped to over 110bhp.

The petrol would need greater modifications to achieve these figures (like you said)

We do have the FSI and it is a 1.6 and is 100bhp

Thanks for that shezlee but if you read the above - Mal was talking about the PETROL 1.4 that is used in the Fabia and Polo. There appear to be 2 flavours in the Fabia, a 68PS and 100PS 1.4 Petrol. The 68PS is 4 cylinder 8 valve and the 100PS is 16v and I presume FSI. It was this unit that I mentioned was not available on the A2. I wasn't talking about the 1.6 FSI or TDi at all (which as you correctly point out is 6-valve 3 cylinder and chippable to 100BHP+).

There is a member of the german A2 forum who had his A2 Petrol tuned to 130 bhp... but there were some serious modifications involved. If anyone is interested, I can ask him..

Bye, Frido.

Hi frido.....can you ask him about his 'mods'....also,which one of the many changes to his car,he would most recommend.

[frido]

I asked him and it seems I misunderstood, he had his 1,4 petrol chipped to 100 bhp, one company offers a 130-150 bhp Turbo conversion, but it is around 5000€. He had a new chip put in and a new air filter (around 550€ for the whole kit) and he seems pretty happy with it (although you have to run it with 98 ROZ Fuel at least)

The company that did it is called SKN tuning...

As I said, all info is second hand..:-)

Bye, Frido.

P.S: I checked their website and it seems their UK branch can be reached via http://www.scottsmototune.co.uk

What is the secret? What do they know about chipping the A2 petrol that other don´t know?

I was speaking to Mike from Jabbasport the other day and he was telling me that most TDI's are using almost max boost anyway, when they chip a TDI they usually just increase the fueling. this is unlike a petrol turbo where they also increase the boost.

RTV.
I don't beleive you can increase the BHP for the TDI by nearly 50% from 75 to 110 BHP by only increasing the fuel, from all the comments here and elsewhere you get a better fuel return after chipping.... this is completely opposite to what Mike as stated...

Just relaying information from a tunning company. I was sitting next to Mike with his laptop pluged into my car at the time and he was showing me all the alterations you can make to the chip and there are quite a few.

Below is a quote from the tunning box company which makes plug in chips for turbo diesels.

(only the volume and time of injection are altered, never the injection or turbo pressure).

http://www.tuningbox.com/ANG/p4ang.html

I do agree though that the boost must be increased as well as the fuelling to enable 110bhp, but most of the chips I have seen quote smaller gains of between 15-20bhp. I'll e-mail Mike and find out the before and after boost pressure.

Being greedy then, a decent CHIP plus a Tuning Box would have me in heaven or jail quicker than ever..

As the tuning box is going to intercept information from the new chip and then work it's magic on the new chip's information, this could be very interesting,, I am almost tempted because with my worst fuel consumption so far at 55mpg when driving hard, I haven't got a lot to lose.. things is I am not a speed freak [well not anymore], I just love loads and loads of torque.. and with 258Nm to play with at the moment I would love to see 300Nm.

[Ricardo]

Hmmm...that company produces a box which goes inline with the ECU not a chip. So they use the standard curves but modify quantities. Chips can alter the curves aswell. As Shezlee says, I cant imagine an engine having so much power and torque without increasing compression ie.Turbo boost. Especially considering the fuel savings. Also running the same boost but more fuel means the engine will be over fuelled (or it was running lean in the first place) and lots of fuel sloshing about washes oil off the engine internals etc etc. Mind you I only have experience of petrol engines so what so I know :)

Just had confirmation from a technician at Jabbasports with regards to their 106BHP TDI chip upgrade.

"The power is achieved by an increase in the fueling and a small
increase in boost pressure by 1.5psi!"

Petrol turbos when chipped quite often double their boost, ie my Leon Cupra was running 8-9psi after it was chipped it was running 15psi. Turbo diesels are nearly always running at near max boost and it's the increase in fuelling that provides most of the extra power.

[Ricardo]

Although the maximum boost is only altered slightly I imagine the chip allows maximum boost to come in sooner so there is a larger spread of grunt than previous. Car manufacturers tend to "blend" the boost in to stop the feeling of Turbo lag. A chipped Turbo tends to have its power/torque come in sooner and stronger because of this.

That would mean that a chipped engine would produce more torque at low revs with the possibility of better fuel consumption with the sacrifice of a more sensitive throttle at low revs.

I don’t want to be an idiot, but is there any general opinion as to which sort of chip to go for? A plug in box which I have been told gives minimum of 15bhp extra with the option of enabling about 7bhp more on top, or chipping and getting about 30bhp. Is that extra 8bhp difference really going to be noticed between the two? I wonder due to the dilemma I’m in as to which to purchase. Or could I buy the plug in box, and then get a company to increase the boost slightly on the turbo to gain that little extra. Amount of gain and point of doing this I wouldn’t have a clue. Am I rambling on a load of nonsense now? Help appreciated.

Get the box and the chip and then tell us what the package is like.. if not get the chip, it makes more sense in the long run, better fuel, 50% increase in BHP 30% increase in torque,, what more can I say.

[MunkStar]

Does anyone have a plug in box? If so what about maybe meeting up and trying the combo of box and chip at some point? Slighlty worried the A2 might go ca-boom after a while though if ran like it constantly!!!! 300Nm would be quality, i wonder if that would make me sit back in my seat when i pulled away?!!
Has anyone changed there air filter for, K&N jobby? I've never used them, do u think it a worthy upgrade or is it more gimmiky boy racer crap?

If you run a chip and a box you are in serious danger of running outside the safe design paramaters of what the engine was designed to do. To get more power you need a bigger turbo, bigger intake, bigger injectors etc.

[EF MAX]

What I really need is a 6th gear as this baby could easily pull some more if it had the extra gear,, not too mention the extra fuel saving,, just imagine 70mph at 1500rpm.. and still have enough torque to pull away clean.
