Hi friend of my bought this Blazer and now he got issues with his immobilizer.
I have access to Alientech tuning tools and want to read out the map for dactivation of the immobilizer but I cannot recognize which ECU this is?

What I know:
It's a DELCO ECU with the number 09360605 CMUD
*86CMUD349046LXAK*
Serv. No. 16263494

But which model is this?

Or is there another tool to read the ECU?

Thanks in advance!
