Can someone help me with this file that came with the car I bought? The car is weak at low RPMs and goes into safe mode...
It's an Audi A3 8p 1.9 TDI BKC with reinforced clutch, PD injection, 130hp, downpipe, GT2256V turbo, EGR off.

Hello,

After the reprogramming, which data should be monitored in the logs to verify that the changes were made correctly?

I believe the most important thing is the AFR, so you need
- specified and actual MAF
- IQ
- specified and actual MAP.
- RPM

Is it enough ?

I don't have an EGT sensor, is there a way to tell if my mixture is causing the cylinder temperatures to rise too high ? ...

I created a map for a VW 2.0 turbo, and I'd like some help evaluating it before loading it. I set those degrees because I'm looking for a somewhat harsh sound.
Modify the following maps:

Minimum ignition angle to 23.254
Fuel retard in neutral to 2.0
Fuel retard from 3000 rpm to 6000 rpm to 1.80

Greetings. I am currently having problems with my vehicle after unlocking the unit. It may or may not be related, but I have problems with my vehicle and I am looking for a solution. Can someone look at and compare the files to see if the adjustment of my unit in the Ford Mondeo EcoBlue is OK?

Hello,
if I cold start my 1.5 ecoboost (Bosch MED17.0.1 ECU), it is quite noisy and the idle is hunting. After ca. 40 sec, when closed loop starts, noise gone, and rpm is stable. With warm engine, no starting issues. No DTC, or any other problems. If I disconnect the MAP sensor on manifold, also cold starts perfect. What I've done, without any success:
MAP sensor swapped
EVAP and PCV blanked on intake
PCM adaptations ...

Hi, this is going to sound weird, but after my tuner disabled my cold start, my auto start stop stopped working. I don't care for it, I know it has bad implications for the engine and annoys the hell out of most, but I'm deadly curious why this happened and my tuner isn't too responsive to explain.

Could this have been done accidentally, due to some temperature thresholds for example? Or could he have used ...

For any newbie who doesn't understand WinOLS which is referred to a lot on this forum, take a look at this video on YouTube which is useful:-

Hi

Bosch EDC15C2

I am unable to clear fault codes on this ECU. I read that after 50 clears the EEPROM bombs out.

How can I reset it please?

Can provide EEPROM read from 5P08C3 chip if necessary as I understand that is where DTC registers are stored?

Thanks in advance of any help as I am properly stuck. Been chasing down a presumed wiring fault ...

Hi everybody. The westgate turbine is installed on this car from the factory. Can anyone "teach" this ECU how to control VNT? I tried a lot of options, but nothing helped. I don't have a damos file for this ECU. And damos from Alfa Romeo 147 with a similar ECU and engine is very different in file structure.

Hi,

I am looking for pointers on the above fault.

The 3rd Piston Deactivation solenoid on a Bosch CP1 should be energised at idle according to the CP1 manual.

I have a Lexia trace from 2.5 years ago where it says it is active ie YES. There was no DTC back then.

About 1.5 year ago, I ended up doing a Frankenstein repair to the ECU. It doesn't seem to be in the area of ...
