Pro Boost FSI remap

Has anyone using the re-map noticed any difference in power / MPG ?
Hi I’ve been running the pro boost for a few weeks now. No improvement in mpg (but I do have a heavy right foot), but to echo my initial enthusiasm it’s genuinely a different car. It’s revvy, responsive, like an old school hot hatch. I really wasn’t liking the car before (despite the mega spec), but now I love it.

My understanding of the chemistry/physics is for the car to run so much cooler (as there are no changes to the cooling system) it must use slightly more fuel...full stop. The timing of the opening of the thermostat only plays a very minor role during warm up and by my understanding be fully open for the vast majority of the time. However its probably a small sacrifice for the longevity of what was prior to Proboost, viewed as the weak link in the engine line up. A happy Proboost user :cool:
 
I finally got round to fitting the proboost ECU after the car was off the road for a while with a cracked thermostat housing.

After fitting, the EML went out and the throttle response has greatly improved as has low rpm power.
Better acceleration, up to 60 at least, not had the chance to go much faster, probably needs a new air filter...

Pleased with the result.
 
Good evening all

I’m now officially an FSI owner and as with my other projects, upon purchase I immediately started looking at ways to improve it.

My biggest concern with owning an FSI were the well documented running issues. My research in this area led me to a post back in 2018 on this forum with mention of a remap being used by the German forum that eliminated a lot of the issues associated with the FSI.

The journey of this remap started in 2015 when the German club a2-freun.de approached an established tuning company in Germany called Pro Boost. Prior to being approached by the Club, Pro Boost had not heard of the FSI engine fitted in the A2 or of the problems associated with it.

The FSI runs in 2 settings, stratified and homogenous. A video explaining this process is available here

Pro Boost did some initial research on a used ECU and then agreed to take in a member’s car from the club to develop software that eliminated as many of the associated problems as possible. The software was ready by June 2016. At that stage they offered 2 stages of remap:

Stage 1 –
Shutting off the stratified injection, running homogenous mode only
Egr valve permanently closed to prevent clogging the intake side of the engine
Swirl flaps always in the open position to prevent seizing of the mechanism
Deactivation of the NOx catalyst and sensor. With the car not running in lean stratified mode anymore, they are no longer needed.
Reduction of the coolant temperature from 105-100c to 90-96c to prevent the plastic coolant pipes from cracking.

Stage 2 was planned to gain additional torque and power. It contained stage 1 options plus

Optimised camshaft maps
Optimised ignition angles

Testing of the stage 1 map went well with great results reported, but with the use of the stage 2 settings, a number of cars were experiencing issues with knock and the cars were then retarding the ignition to prevent this. This was found to be as a result of the age of the injectors on certain cars and so stage 2 was shelved. The successful optimised camshaft mapping was retained however and added to stage one.

So there is now only one remap and it has the following features –

Shutting off the stratified injection, running homogenous mode only

EGR valve permanently closed to prevent clogging the intake side of the engine

Swirl flaps always in the open position to prevent seizing of the mechanism

Deactivation of the NOx catalyst and sensor.

With the car not running in lean stratified mode anymore, they are no longer needed.

Reduction of the coolant temperature from 105-100c to 90-96c to prevent the plastic coolant pipes from cracking

Optimised camshaft maps

The mapping process adjusts the settings within the ECU so that no engine management light will be triggered by the settings it runs. The engine management light will however still be triggered by other engine faults it identifies. In essence, you won’t lose the functionality of the EML system.

Whilst performance gains will be experienced due to the flaps running fully open and camshaft modifications, this map is marketed more as a preventative measure to improve the longevity of the FSI and make the ownership experience less of a gauntlet.

The price of the map is 300 Euros. Depending on exchange rate, that works out at around £255.

The process for purchasing the map would be as follows:

I will order a stock of ECU’s from Pro Boost (I’m hoping for around 4 at a time).

You can place an order for an ECU from me and it will get sent out to you by courier.


You will fit the re-mapped ECU to your car and send your current ECU back to me.



In order for this process to work, the remapped ECU being sent to you will need to have an unlocked immobiliser so that it can be plug and play into your car with no coding required. This will mean that the immobiliser will no longer be active on your car. I accept that this is a downside, but it is the only way the service can be offered and I’m hoping that the benefits you receive from fitting will outweigh this issue.

************************* Update 4.6.2020, Tom @timmus has offered to re-instate the immobiliser function on a remapped ECU free of charge at his home, or for a 'time' payment whilst on a tour***************************************************

To ensure that I receive an ECU back from you, there will be a surcharge on the ECU of £40, that £40 will be refunded when I receive your old ECU back in the post. Alternatively, if you wanted to keep hold of your cars original ECU, then you could purchase an FSI ECU from ebay etc and send that to me instead.

I don’t claim to be any sort of expert on FSI’s and indeed I am just starting out on my FSI journey, but I do know that the German owners club do not suffer fools and will only use the best products. Pro Boost are also an established German tuner who have a lot of experience mapping all makes and models of car (https://www.facebook.com/ProBoostEngineering/). This map has also been run by members of the German club for around 3 and a half years now with no issues reported.

I am in touch with Adrian from Pro Boost, so if anyone has more technical questions they want answered in regard to the map, then please just ask and I’ll pass the message back.

I plan to run a copy of the map once received and will report back my findings on its use.

If you would like to purchase the remap, please either reply here or send me a PM.

I would like to purchase a remaped ecu for my fsi 03 thanks
 
Hi folks,

Here's a helpful video for those who have or who are planning to purchase one of the Proboost ECUs for their 1.6 FSI.

Big thank you to @timmus for his voiceover and demo and my apologies for the rotation of the camera part way through the video.

Hopefully it'll avoid some broken cradles!:

Thank you James for that and Tom @timmus . This is why you shouldn’t leave it to a breaker to show you have to remove it. I used the sledgehammer approach where Tom used the far more refined version of intelligence over brute force.

Well done @timmus and @jaffa_jim that's absolutely brilliant! Removal is certainly not very obvious: ask me how I know :rolleyes:
 
Yep, having removed large numbers of TDI, MPI and FSI ones in the past I’d never noticed the difference. Sorry to anyone who damaged their cradles in the process.

I hear you and glad you found it helpful.

Like you, I'd struggled to work out which part to press, and where to pull, since it does differ from the 1.4 petrol and the TDIs.

So I made the request to @timmus when he was fettling the FSI to resolve the issue and to make a small "how to". The desire to share knowledge is one of the greatest aspects of the Internet and A2OC is a shining example of that.

Thanks again Tom!
 
Hi, i owned 2 fsi, one with a P1031 and the other a NOx problem! With a Proboost ecu without immobiliser, is it possible to install it from an A2 to an another? Or does the ecu become linked to the car? Sorry for approx English..

You can move it from car to car ?
 
I want to keep my silver sweetheart for years to come. But after 3x repairs to the intake manifold (17439 :mad:) I started to have doubts. Thanks to the German forum (and this one also of course) I have had the ECU tuned by ProBoost in the hope that the manifold problem will no longer occur.
Today I replaced the ECU and am very satisfied so far. The hesitation when accelerating around the 3000 rpm range is gone. Good to see that the water temperature no longer rises above 96 degrees.
I also have the Color-FIS (installed by famous Timmus ;)) and I can see the temperature fluctuating between 96 and 86 degrees. The temperature needle is rocksteady at 90.
And I think I will have to wait and see. In any case, I'm more in love with my silver A2 again ?.
 
I’ve today sent off a batch of 5 ECU’s to Pro Boost for mapping. This will likely be the last batch to go in before Brexit.

Indications are from a lot of carriers that there will be additional import duty on items coming in from the EU. If this is the case then this will inevitably put the price of the remap up.

I’m not trying to push my wares, Iget about £30 for every unit sold so it’s not going to make me my fortune; but if you have been considering one of these units get onto this batch because I can only imagine the price is going to go up.
