Marelli MJ8F3H MJ8F3HW20P , need coding from Automatic Gear box to Manual

[MadridEcu]

Hi guys,

Recently i performed an IMMO OFF in this ECU. The inmo OFF seems good, but the car not start correct all times and someones won´t star.

No immo DTC relates codes.

THe only problem (I belive) is the used ECU coming from an automatic model and not recognaize "P".

Any one Knows how to coding the information in the ecu?

My car ins a Fiat fiorinno but the ECU come frome a Citoren NEMO. May be with Citroen OEM tool????'

Thanks in advance

Wont argue with you *TRY* fill eeprom with 00
install into car, ignition on DO NOT TOUCH ANY PEDALS for 5 minutes
then ignition off, read eeprom, what is changed cut and paste into your good dump
and run.

try not to trip over dk thanks button, you have plenty to spare

Its not just coding you need to change flash for manual transmition

Thanks to both of you, at the end i bought an used manual ECU for 70€.... May be if i readed this before i try your method. I will post my results with the used ECU in any case and compare the files.

Thanks

Meat-Head again. I do a new inmo off in the "new" used ECU and car still with the problem based on this we discard ECU problems. I think the problem was that the engine becames from a donor car and last owner maybe not bought same engine. But after discard ECU my customer didnt continue in my garage with the diagnostic because he is a mechanic and prefers continuo himself.
