What PCM do I have? So I've been trying to figure this out. I'm building a TT LM7 and the PCM I got with the engine and harness I dont believe to be natural to the engine. The PCM anyway...
Its a RED BLUE Warren PCM.
The service number is 09354896. This leads me to believe the PCM to be a 99-00. I know the engine is from an 02 burban.
The hardware number is what I cannot decypher. 09380120. This hasn't popped up on any ls derived charts I've found.
What PCM do I have?! Can I even use it?

The 896 PCM should work fine with any LS1 engine or even 24x LS2.
However, I would swap to a 411 PCM.
According to this thead, a 896 can be upgraded to a 411:

My research says the two are essentially identical inside and there is no performance advantage to the 0411.
Once you upgrade to the 3 BAR OS, they are identical.
What is going to be important is the Operating System currently loaded onto your 4896. Not all are upgradeable to 3 BAR. So you need to read it with HPT and see.
You might have to load an OS that is upgradeable.
