How to find IMMO bit.

by **jkobal404** » Fri Nov 07, 2025 9:17 am

Hello everyone,
I recently got into ECU tuning. But i have issues. Can somebody share how to find immo in eeprom. What bytes are for keys hash, vin, immo bypass for new ECU's and where to learn this, do you need someone to figure it out or do you manually look for it. Also what needs to be deleted to put ECU in virgin state. Help would be much appreciated.

Firstly you missed "Introduce Yourself" and secondly you didn't say what ECU you are inquiring about.
