I have a 95 Firebird T/A LT1
It is bone stock except for headers, 3.73 rear gears and ABS has been removed.
I am going to need a ECM. I have seen them advertised from $150 to $800..what is the difference? None that I can see. Some of them get flashed with the receiving vehicles VIN which may be for security systems.
Can I just take an ECM out of any old 95 LT1 Firebird / Camaro?
Thanks...
