You can read/write/clone this ECU with IOTERMINAL using the SIEMENS license.

if it's same as opel / vauxhall then believe kess clone can do it, I have flashed one before.

You are completely wrong. Opel has 71.6 and Chevrolet 76.1 It's not the same. And 76.1 never has been used on Opel.

Either way, they are both GM and ioterminal (with Siemens license) can definitely read/write this SIMTEC 76.1 ECU. I'm looking at it in front of me right now.

You're right, was probably simtec 75, was 1.8 vauxhall and kess did that fine so not sure on 76.

ECU Siemens 76.1 replacement
Immo is in the calibration? Can I make a clone using Kess?

Immo in eeprom. Eeprom emulated in flash. Kess can read only part of flash not all.
