Good evening all, I have tried to scodificare a iaw 5af, that small as the 59f to understand.l I put it in the boot read with the galletto processed with immo Universal devoding and in the process of writing appeared to me to be a message that would not correct the checksum, I have given ok equally pensado who had already fixed the software, at the end of the writing I wanted to try the ecu on my 600 that mounts, however, a 59f and when I go to turn the ignition you hear a strange noise in the relay and the machine will not do you think it is a problem of the checksum or is it a problem of the ecu given that it is two ecu's different?
