Title: Can the IMMO be flashed off on already tuned ECU's? Post by: stuklr on October 30, 2013, 03:11:50 PM If the ECU has an existing flash on it but I want to move it into another car?
Buddy has a GIAC ecu for an 01 A6 2.7t and wrecked it. Wants to stick that ecu into the new replacement A6 2.7t. Both cars have immo. Can I just flash off the 95040 eeprom in boot mode? Or will the GIAC software be upset by this? Thanks Title: Re: Can the IMMO be flashed off on already tuned ECU's? Post by: jackson.amrol@gmail.com on October 30, 2013, 06:26:58 PM I believe you can read the eeprom, modify it to immo off and write it back as the modified maps are hidden in there. You just don't want to use an eeprom file from a different ecu

Make sure to read and write it in bootmode, and not read the file with nefmoto. Title: Re: Can the IMMO be flashed off on already tuned ECU's?

The cluster just provides power to pin 21 right? So thats all this ecu needs to be happy in a different car even with the immo right? The car he is putting it in has the same gen immo and wont be upset because the keys match right? Or will the ecu know its in a different car and lock-up?

Argdubs too will do it, but needs to be bootmoded to write the modified eeprom back.
