Bosch MP9.0 ECU 2.0l Map Required

**Tefocm** · 8th August, 2014, 11:45 PM

Hey guys, im working on a conversion in the workshop, upgraded a 1998 VW Polo from 1.4i to 2.0i, maintained the same wiring and ECU, and so im having air - fuel ratio issues. Anyone have a Map that I can use on the original ECU to help keep the idling smooth without having to disconnect the MAP-Sensor?

Its a 27SF256/512 (the square type one), the other ECU I have is 27C256/512 (the long SOP28). Can you help?

Thanks a'millie ma boet!...Il give this dump a try and get back to you yeah. All I have to do is write it on my ECU write? Is it stock or tuned?

It is stock but remember you must use a new ic because those ic s are OTP

I know. But here is where I have a problem: Will this EEPROM data work on my ECU? If its stock which ECU did it originally come from?

Guys have any of you experienced the rev counter being stuck at 3000rpm and you can only drive the car if the speed sensor on gearbox is unplugged.... This is only after putting the 2.0 map on.... Any ideas what the issue might be?

Yes it is easy to rectify but in the meantime unplug the speedo drive and you can drive it
