News of Fine Tuning, Testing, Diagnostics and Analysis

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 ...

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 ...

I built a engine forged conrods and pistons (slightly higher compression) stock head. Hardware mods: Large front mount intercooler with upgraded boost pipes, Downpipe 76mm, Full stainless 76mm exhaust upgrade, Upgraded coils, Duel Hybrid turbo (IS38), Water-methanol injection system 50/50 mix ratio.
I started the engine and did all basic adaptations and settings. All ok. Drove the car for about 3000km on the stock tune with decat off only. No issues. Thereafter i loaded a ...
