Hi all.
I have a ECU with problemms in the injection control driver, but i cannot identificate what is the chipdriver inside ecu. Need too some information about the pin data or schematics for this engine. It is a Fiat fire 1.3L 8V Benzina engine ECU type IAW 4AFB.21. .
Any help will be appreciated.

Very thanks. Exist some software , book or programm where i can get this information in the future?

the only thing i know is the reverse engineering and the knowledge of some partner who just have discovered some things inside the ecu
If we want to learn more about the ecu?s inside behaviour we must cooperate all together
