Pro Boost FSI remap

Oooh! You've inspired me... I was going to wait until the weekend to fit mine, but might just be a job for this evening.

Our Fizzy currently runs very sweetly, but it does sound like there's some baseline improvement even on that with the proboost 🙂😎
 
Fitted my proboost at the weekend and took the FSI for a proper run tonight. After a fair bit of remedial work a few months ago including new sparks, new timing belt, new injector, new ignition coils, and oil/filters change, our FSI was running pretty well already but it 100% runs better with the proboost. Acceleration is smoother and it it has noticeably more torque in 4th/5th gear. I’m very happy with the difference it’s made and recommend it.
 
*****UPDATE JUNE 2022*********
ProBoost will no longer be offering UK buyers the option to buy a remapped ECU direct from them in Germany. I will now be the only source for UK FSI owners to purchase one of these units.

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 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***************************************************


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.

Hi Steve,
I have been recommended to buy one of these from you by another member to rectify a very tenacious misfire on my mother's 1.6FSI.
How do I go about ordering one?
TIA,
Tom

Hi Tom

Unfortunately the latest batch have all sold and I’m not sure when the next batch will be sent back out to Pro Boost.

Darn!
If you could let me know when the next batch are in we'd be very interested in purchasing one from you to get ours back on the road!
Many thanks,
Tom

Hi @ShadowProjectFSI Do you know the cause of the misfire?
Have you got a diagnostic scan?
Seems a shame to keep the car of the road.

Hi Mac,
The scan showed an error with the intake manifold slaps and "random multi cylinder misfire" if I remember correctly.

Unfortunately the car has been off the road for a couple of years now, while we've tried pretty much everything to rectify it.

The ECU will be our last attempt at fixing it before we reluctantly part ways with it!

Cheers,
Tom

I finally installed the Pro boost programmed ECU and drove with 98 and then E85 no funny stuff or error lights. Car has been offroad for a year and don't have MOT so used only at our privat road, I haven't driven it so long time that I don't have good reference point how it should behave. At least no misfires which I couldn't solve by trying everything I have found on internet. After freshening up and MOT I do some finetuning with Unisettings. This would be nice car to drive in France as they pay only about 0.8€ = 0.7 GBP per liter of E85. I think E85 is not sold in pumps at UK so my experiments don't interest many in this forum.
 
I'm not sure that you should run an FSI on E85. We've not long had the rollout of E10 in our standard 95 fuel in the UK and the VAG 1.6 FSI from the early 2000's was on the list of engines for which E10 is unsuitable. Although it would run on 95, the FSI always did really need higher-octane fuel and long-term use of 95 would lead to issues. Now in the UK only the 98 is still at E5. I realise that E85 is even higher octane than 98, but if the 10% ethanol content wasn't suitable for it, how would it fare longer term on an (up to) 85% mix?

Audi have stated that the FSI engine tis not compatible with E10/95, so E85 is definitely out.
Use E5 98/99

For what reason though? Is it due to the carbon build up in the inlet causing rough running or some other fuel line/seal issues. The ProBoost ECU was designed to also allow the FSI to be run on 95ron, but we don't know the reason why Audi say an ethanol content fuel isn't suitable.

It's likely to be that there is a material used in the engine that is adversely affect by the alcohol.
Only an assumption on my part though.

It could also be because of the very different pattern alcohol blended fuels burn, compared with fuel with little or no alcohol content.
Injector size, and spray pattern may also be factors, you need a higher volume of alcohol blended fuel for the same energy.
Maybe ProBoost have more info? The ProBoost remap came from the German market, and I'd bet similar questions have come up there.
Mac.
 
1.6 FSI is first gen high compression engine designed for RON 98 fuel with lean burning stuff so Audi can't say go ahead and use 95 even if engine don't have problems with that 10% Ethanol. I don't think there is a RON 98 fuel with 10% Ethanol?
I had misfire problems without error messages with 98, I did a lot of cleaning and changed some parts without luck and this ECU mapping was last effort before engine out. As I have experimented with E85 in different engines my Ebay buy ECU was programmed with very basic E85 settings which I can fine tune with Unisettings. Cold engine enrichment range isn't enought without programming the starting point with real permanent tuning.

E85 in my country is made of biowaste and usually is cheaper than 95E10 even with energy content calculated, so renewal energy with over 100 RON.
Yes I know I can get problems with E85 but my FSI hasn't never been trouble free and I'm little bit worried about the special rotating high pressure pump which are unique in these early FSIs.
