I'm not sure if you've asked, but the folks on here might be able to help with the underlying issues with the fsi, if you start a thread. Some fsi issues are well known and folks May be able to help. Having said that I had an fsi that did all kinds of strange things once up to temperature, loss of fuel pressure and cutting out. Good luck.
Pro Boost FSI remap
- Thread starter A2Steve
- Start date
@SLEI Good Afternoon,
Fairly clear what has happened, ProBoost assumed the ECU was for your car and left the immobiliser function untouched.
You ask about options, surely the simplest cheapest option is engage a skilled local auto enectrician to match the ProBoost modified ECU to your car. If no one local is available I imagine Tom(Timmus) could remove the immobiliser function if you shipped the ECU to him by arrangement, but this would incur extra postal charges that you have hinted is expensive in Finland.

The FSI is not compatible with E10, according to Audi, so E85 is a definite no no.Are you sure E85 is suitable for your engine and climate conditions?

Its a bit like trying to cure one problem and introducing a far bigger one. The ECU has been reprogrammed at Pro Boost but was it for the same issues that @A2Steve had them resolve AND for the E85 fuel or just the fuel? I would have thought it obvious if sending a second hand ECU that you had never tried to have them remove the immobiliser, after all you did not know the code to start with or if the ECU was working or had an immobiliser issue already.
Also think a full VCDS scan would highlight the issues and point whoever is going to work on it in the right direction.

I have read "everything" about E85 from people actually using it in different kind of vehicles in Finland. Some have used it year round even at -30C without preheating. In very cold a lot of it have to injected on cold start so short trips dilute oil easily.Are you sure E85 is suitable for your engine and climate conditions?

Torque on my FSI below 3000 was like my chipped A2 1.4 TDI when I used high % of Ethanol.
E85 or RE85 as company ST1 calls it, makes it from biowaste and Ethanol part 85% is very constant year round not like in USA.
Last time when I have tanked it at winter it had a little bit of LPG marker smell in it so I think they spike it with Bhutane or Propane gas to aid starting. E85 is a lot cheaper than 98 and has higher octane rating and it's 85% domestic made of waste so many plus sides.
E10 fuel is at least my country 95 octane so no go for FSI.
Proboost did knew that I bought random FSI ECU from Ebay and had never been plugged to my car. There was so much writing about IMMO being off that I didn't think about it at all.
Proboost takes the IMMO off if I send them the ECU but I would like to test did the programming work to my problems.
I have more work to them but also but can't get responce so can't act on other works.

Yes but are the rubber seals, gaskets and other fuel parts on your A2 capable is having E85. Audi does not even recommend E10 as compatible with the FSI. Concerned that you may be making a bigger problem here. You buy an FSI knowing it requires Premium grade petrol that is more expensive. You have to listen to what the manufacturer states as a suitable fuel. Go beyond that and it is very much at your own risk and doubtful if the club would want to get involved in this.

I wonder if @Rickmeister could help out, if a batch were to be sourced, and pre paid?
I am looking at an alternative solution for transport, but unsure when any trip would be made.

It’s not an upgrade as such, it fundamentally changes the way the engine works to resolve a number of common FSI related issues.
In the event you’ve got a fully functioning FSI it can be seen as a preventative measure though.
Sorry poor choice of wording by myself I meant resolving potential flaws in the original mapping to allow reliability and prolong the life of the engine which is always a great step forward

The best mod in my opinion is to allow the engine to run at 95/98 degC, which should give the cooling system, especially plastic parts an easier life.
Spud has been running a PB ECU for over a year with no issues.

If temperature is an issue and this might sound like a really stupid question here ( Sorry in advance ? ) but would using waterless coolant help ? ( IE no water no boil )
I had the Evans waterless coolant added to my this wife’s Corsa Clubsport VXR ( changed at just 500 miles old as we bought the car from new ) as they suffered from piston 4 issues.

Coolant temp is over 100C (109?) in some parts of engine and it's not boiling. Just longer life for plastic hard pipes when they are in cooler -10-15C temp.

The FSI must be run on E5 (5% alcohol) petrol, as E10 (10% alcohol) will cause engine damage. Nothing is do with octane rating, but only 98/99 super Unleaded is E5.
Mac.
We were talking about temperatures not octane rating. I have tested upto 75-80% ethanol without more problems than 98E5 so I don't share Your opinion. Stock 1.6 FSI is 98 octane engine and at least in my country 10% Ethanol fuel is allways 95 octane rating so Audi can't approve it.

I have ran a 1.6 Fsi with proboost ECU in combination with Tesco premium fuel Results:
1) EMl light that was on due to manifold flap set point not met issue, went off & remaind off
2) smoother engine & ride quality
3) Hesitation disappeared & car more responsive
On top of all this, I belive with proboost the EGR is deleted as well as NOX sensor together with lower temprature cooling system though the temp gauge still shows 90.
I belive high octane fuel makes a huge difference to the Fsi running & proboost is the ideal remap for Fsi's currently with or without Eml issues etc
The above are my findings, hope it helps FSI owners
Cheers

I use Evans waterless coolant in my Fsi ,The problem with coolant system is higher temperature which causes higher pressure,with Evan's you eliminate the high pressure completely
