Default What computer is for a 24x LS2 engine?

Is it the E40?

As I recall the E38 was for the 58x engines and the E40 was for the 24x like in the 2005 Vette.

Anyone know the GM part number? Also, I need to buy one asap. Any leads? (the dealer was no help)

Thanks!

The pcm out of my late 2006 GTO has the following info on the label.

12604791 YMUM
Delphi automotive systems
Barcode:

Service number: 12596679
5349

The service number comes up on some of the GM direct parts websites for around $280

I hope this helps.

But isn't that a 58x reluctor LS2? If so then it's the E38. I'm also not sure if the plug is the same for the fly by wire deal.

Here's a pic of it. Like I said, I'm unsure what other vehicals it's found in but I know it was in the '05 LS2 Vettes.

You could always pick up the cheap n' plentiful 99+ F-car PCM. It works with the 24x wheel obviously.

But not with my fly-by-wire throttle body

The older LS1 PCM will still work with the Fly by wire throttle body. You would need a TAC module and pedal from the older car/trucks.
As for the '06 GTO box, it is an E40. The GTO's never came with a 58x LS2, not even the '06.

Well, I really don't want to redesign the whole car.. lol

Installing a diff pedal assembly would be a royal PITA. Good to know about the GTOs though, thank!

I found a contact at GM that had a couple "laying around".. they're on the way.

Will be nice to have a spare all programmed up and ready to go
