Boost problem

[UrS4boy]

My ecu is for a car with an automatic transmission. My car is manual. I do not know if that's a problem.

I believe it's a problem in the sense that the autobox ECU limits boost/hp at certain times in order to protect the autobox from excessive torque. The engines are supposed to be the same but the 0-60 mph times are about 1.7 seconds slower for the autobox than the sedans (IIRC).

Try swich ecu with some friend and see if there is any diference
p.s. nisam znao da ti je ecu od automatika,treba si mi odma rec.Sigurno je on problem,mada evo iznad mene ti je post prakticno sve objasnio.Zato ti ne ide u full boost

I talked with a friend and he said that he put such ECU in its 200 20v. But before all that changed two chip. He had no problems. I will try my ECU on the car of my friend and we'll see. It's the only way.
But ... As you can see neither idle just not ideal. The compression in the cylinders is 11.5 bar. All are the same. Car does not smoke. I paid for cleaning injectors, I do not know how the business is done.
Spark plugs are new.

It is interesting that this ECU s4. But it works recognizing key code.
Work and airbags, even though I think it has nothing to do with the ECU.
I have a fear, if I buy the ECU from s6 I have problem with the immobilizer and if buy from s4 again I have a problem.

Can u test your car with other ECU from s4? To see will it work like it shud

[igor136]

It is a good idea but I hardly find someone to lend me the ECU. Within a radius of 300 kilometers around me there is no one aan.

[igor136]

But s6 automatic also has a 1.2 bar boost.

That would not work if your friend still has the single coil 3B ECU. The AAN/ABY/ADU ECU's all are based on firing 5 individual coils, not a single coil with a distributor spinning around.

If you unplug N75 and you have 0.8 bar boost, it means spring is not stock in WG.
Also, I told you exactly what to do to fix your problem, now it's up to you to use this knowledge.

Your "problem" has nothing to do with the ECU. People are always quick to blame that which they do not understand.

Dimitri I find your brutal reply's a source of great entertainment. I just love the fact that you take no prisoners

I thought it was just me

....Your "problem" has nothing to do with the ECU. People are always quick to blame that which they do not understand.

So you don't think the fact that igor136's ECU is a 551B from an autobox UrS4 is in a manual UrS6 with immobilizer has anything to do with *any* of the issues?

I agree that 0.8 bar boost with the N75 disconnected implies that the WG spring is a 1.9 Bar (or the like).

Precisely.

[UrS4boy]

Precisely.

So autobox chip maps are the same as manual chip maps for the AAN?

The ECU doesn't know what car it's in

Duh. My contention is that if the ECU is for an autobox AAN, the maps in the chip set are different than those for a manual in order to limit torque on the autobox. On that basis, the autobox ECU would work in a manual AAN UrS but the car would not perform as well as it would with a proper manual ECU. The chip set numbers that igor136 PM'd me are nothing like manual chip set numbers that I have encountered before.
