Hi guys,
Which ME7.5 would be interchangeable with 0261206269 06A906032AF??

It's a narrowband ecu so most likely narrowband mk4 year 2000ish? I'd ditch the narrowband, swap in a wideband ecu and o2 sensor ad a few wires to the large loom plug and run wideband setup. Code out vvt and use a better defined wideband file. Just my opinion

OK, guys I have WB ECU and sensor already.
What's the easiest way to convert? I have googled already and there are several old topics about conversion, people are playing with resistors on VVT wiring etc... Basically WB sensor wiring is what I need, VVT can be disabled in the ROM file, yes?

Update: I have fitted "wideband type" ME7.5 ECU with 800BB/1MB chip. Immo Off EEPROM which I found in nefmoto was loaded with exe tool in CMD and 06A906032HS file loaded in bootmode. Now I have some problems:
1. Car starts, but only idles, I am not able to make TB alignment;
2. I can't recode ECU, as car is Euro A3 I tried 06A906032HP file, still no success, ECU doesn't accept new coding. Same problem with TB alignment.

What might be wrong? As I understand there is some kind of incompatibility.
