GTV V6 CF3 ECU original map needed!
I am having a problem with Alfa GTV V6 CF3 (2001). Car idles roughly - vibrating badly almost like a diesel when warm. I can feel a misfire and it lacks power until 3000rpm. Over 3000rpm it flies like a monster. Sometimes I feel like a lag to throttle response (when I remove leg from a pedal, but it still revs up a bit).
I had checked the timing, changed sparks, coil plugs, throttle control unit, MAF, checked for air splits, injectors, checked all the connections, removed and ran a car without lambdas, relearnt potentiometer, checked compression and many more, but with no success.
When logged into ECU, I find an error "P1314 Vertical Accelerometer / Uneven Road Surface", but this car has no accelerometer installed from factory, so that doesn't say much.
Previous owner told me that the car had ECU remapped, which I believe might be the reason for my problems.
I suspect having wrong or incorrect map file installed and now trying to find the original map file to restore it to factory condition.
Has anyone got Alfa GTV V6 CF3 160 Kw? I would appreciate if you could share your ECU map file with me.
Cars with that ECU were made from late 2000. ECU Bosch ME 3.1, Bosch part number is 0261206660.
