someone tell me if the microcontroller used in the ecu MARELLI IAW7GF is MOTOROLA or STMICROELECTRONICS?
someone also knows an interface to read and write this ecu?

Hello that, you need to do the procedure with the UPA, 7GF Reset is called, active and you record it in the memory of the ecu itself, change some lines, place the ECU the car in contact and it is paired with the BODY, greetings.

RESET VIRGINIZE MM MARELI IAW 7GF.NL FIAT FIRE 1.4

PUT THIS ON THE LINE : 0000D0

47 16 FF FF 00 00 00 00 10 D4 FF FF 00 00 00 00

AND PUT FF ON ALL THIS LINES:

0001E0

0001F0

This is a reset procedure for this ecu!
Test by yourself and press thanks. sorry for the bad english...

BRazil!
