Remap advice for a complete noob!

I'm new to the a2oc & I have had my Audi A2 FSI Sport for nearly five years now, it's an 02 plate. It has done 101000 miles & is just having the inlet manifold changed due to the P1031 code that seems popular. Is it worth getting a remap done? I know very little to nothing about cars. I love my little Audi & do not want to ever get rid of it. So, can anyone point in the right direction of a reputable company, I'm based in Norfolk, that can remap the car if it's worthwhile doing?

No doubt I've missed some vital information, so I will post any details that are needed.

Thanks in advance,

Stuart

A remap is well worth doing, but speak to Stealth Racing first, Warwickshire I believe? 01926 812259

They are the experts in remapping the A2 and they will tell you what they can do for a FSI. The results for a TDI map are amazing, but there is less scope for a non turbo engine I believe.

Steve B,

Thanks for the reply, I will give them a call & see what they can do. I was worried due to mileage & age of the car.

Condition and service history are more important than just the mileage alone. Some low mileage cars have been mistreated and some high mileage cars are in fine condition, but Vince is the man, he will advise you when you give them a call !

I seem to remember reading a thread about Vince's efforts at remapping an FSI. With so few variables to play with (compared to the turbo'd TDI), I think he managed to squeeze something like 4bhp more from it. The general consensus seems to be that remapping a petrol A2 is simply not worth it.

Cheers,

Tom,

As a complete idiot when it comes to cars, what variables do you mean? I have read the mod forums & everyone says that a remap is a must. That's what has got me thinking about a remap. I've decided the car is going to be a keeper. I tell my wife it's like the Beetle, it's iconic & will always be desirable. I just want to spend a little cash/love on it so it keeps good & remains nice to drive (well a bit bumpy but I like it!)

That sounds about right Tom, but sometimes the existing settings can be a bit off and sometimes just correcting that can help a little, but as you say, probably not worth it (I suppose if you have improved the breathing (intake and exhaust) you might get a little more from a remap, but not much "bang for your buck"

They're talking about the TDI engines ... something like a 25-30% improvement after a remap. From what I understand the petrols can't be remapped effectively, because they don't have turbos.
 
I think Stealth will offer a similar performance upgrade to superchips - http://www.superchips.co.uk/search?make=2&fueltype=1&model=20&variant=747 but you'll get an engine health check, fine tuning on the dyno, before and after dyno runs followed by a road test and possibly the option to remove the remap if you're not happy with the results.
It's a lot of cash for a small power upgrade but you may end up with the ultimate FSi engine which has a smoother power deliver and is nicer to drive. Hope this gives you a few more things to discuss with Vince.

Cheers Spike
 
any petrol engine should respond well to air and exhaust upgrades so the FSI should be no different, then get vince to put it on the dyno and fine tune it.

As above you may only gain say 10bhp maybe 15 but driveability and responsiveness will be much better and of course the sound.

As mentioned by Mike, a remap is regarded by many as a must-have for the TDI.

A car's map is basically a software look-up table that lets the engine know what to do based on a series of readings from its electronic sensors. So, if your engine is doing a certain number of revs and is under a certain load (due to going up/down a hill, for instance), with the incoming exterior air temperature at X degrees and the engine temperature at Y degrees, how much fuel should be injected? These are some of the variables that I mentioned in my previous post. A remap is essentially a rewriting of that look-up table.
The TDI has a turbo, meaning there are additional variables that can be manipulated within the look-up table (map) to get the engine to perform differently. The TDI's factory map limited the engine's performance, in part due to insurance, tax and emissions considerations. As owners, we're able to have it remapped and release the engine's concealed potential, without having to make any physical changes to anything. The same is not the case for the FSI. Whilst you can make some physical changes in search of increased performance and 'driveability' - and then update the map accordingly - a remap on its own can't achieve much.

I hope that helps. :)

Tom

Tom's comments got me thinking. Took me a while but finally remembered it was Ben who was the first to have a remap on the FSi. It was a few years ago and things may have progressed but at the time, all in the garden was not rosy - http://www.a2oc.net/forum/showthread.php?6352-Re-Mapping-For-Petrol-A2&p=54273#post54273

To get more power you burn more fuel which requires more oxygen (air). To get more air into the engine you improve the flow (less restrictive air intake and exhaust) and/or force more air in.

Forcing the air in requires a supercharger (turbo driven by exhaust gases or compressor driven by engine) altering the map on a turbo engine provides more fuel and air to give more power.

A normally aspirated (none supercharged) engine receives it's air at atmospheric pressure so the only way to get more air and fuel in is to provide better "breathing" so upgraded air filter and free flowing exhaust. A map upgrade can then take advantage of these modifications.

To get real gains on a none supercharged engine requires mechanical alterations to the engine itself which = £££££
 
With modern n/a engines you can also alter things like the valve opening timing, RPM limiter and of course ignition timing but the gains will always be relatively small - when I had my A4 V6 remapped a few years ago I got an extra 10BHP from it- but then that was a relatively large engine to start with and I was then restricted to only ever running 97+ octane fuel in it.
 
Valve opening timing = mechanical changes unless using adjustable variable valve timing which I don't believe the petrol A2 has.

Ultimately supercharged engines need strength to cope with high pressure and compression along with appropriate flow and normally aspirated engines need high rpm & flow, hence. 20,000+rpm old (pre current turbo) F1 engines.
 
Gentlemen,

Thank you all for your advice. I have yet to call Stealth but upon reading various posts on the forum & all the posts here,I think I will leave the car as it is. I've got my head stuck in the books about cars & how they work! I've never really cared for cars but I've grown fond of the little beast so I thought it could do with some TLC.
