LY6 Conversion - ECM/TCM/DBW Pedal Question I am installing a 2008 LY6 into a 1st gen Camaro and need to know what ECM, TCM, and DBW pedal to get. The engine did not come with a harness, or the computers/pedal. From the research I've been doing, it appears that I need an E38 ECM and a T42 TCM. The question I have is are these two numbers compatible with only certain year model vehicles? I'm told that I need them out of a vette, but not sure which year model(s). Can anyone point me in the right direction?

I have the same engine. As for getting the computers only out of a Vette that isn't an issue. You are correct about needing the E38 ECM and T42 TCM, your programmer will load a base tune into the computers so that is why being from a vette doesn't matter. As for the DBW pedal you can get the vette pedal, or a 2007 monte carlo pedal but that one might need some wires switched, or a truck pedal which is large.

Thanks again. Still learning about all this LS conversion stuff. It's mind boggling at times!
It is our experience that you should use the correct year tune with the correct year ECM.

What transmission are you planning to use? From what I understand the 6L80E does not require a TCM whereas the 4L80E does. No TCM would be required if you're going to a manual or keeping a vintage tranny like a TH350, TH400, 700R4, etc.
Here is a wiring diagram that you may find useful. This is for a 2007 silverado.

I was on Ebay earlier and saw two different part numbers for the E38 ECM's and it appears to be based on year models. The 2006 & 2007 was p/n 12597121 and the 2008 & 2009 was p/n 12612384. Does it matter which one I get? I also saw a 12625455 part number. I found saw a DBW pedal that was listed for a 2007-2011 vette. Will that work or do I need an earlier year model? I just want to make sure I'm buying the right stuff the first time.

Yeah I know what you mean about learning about all of this stuff. I have spent more time on the computer then I have wrenching on the car, and I'm just in the middle of my swap. I would get the same year computer as your engine, just to avoid any unknown issues. Or just give Jon @ PSIconversions a call. He building me my harness and computer setup, and I think it was money well spent to avoid any possible problems of doing it on my own. You can have him supply everything, harness, computer, and pedal... That is the route I went. Just a thought.
