Harness wiring & ECM tune
Harness wiring & ECM tune I have looked on the Lt1 site and find no referance to wiring harness mods for a stock 05 GTO ls2 DBW into a 55 Chevy. Any help would be appreciated. Have electronic back ground just need to know what should be deleted? Paul
Some say the 05 GtO 24x is strange in some ways?

1. As Merv said, you can run drive by cable (aftermarket throttle body with your LS2 intake) or switch to LS6 intake with camaro throttle body) and an LS1 (Red/Blue) PCM. This may be the easiest way. PSI has all the parts and a plug and play harness for this. (FYI, we did this on our 71 Nova LS2 swap).
2. You can go rework your stock E40 harness. PSI does not perform harness rework, however, there are plenty of people out there that do.
3. You can stick with DBW LS2 throttle body you have but run the LS1 (Red/Blue) PCM with corvette TAC (Throttle Actuator Module), Corvette Pedal and TAC harness. This is a little more expensive than option 1 or 2 but it would be done with a new harness and components.
The E40 controller that came on the GTO is not supported by any major harness manufactures that I know of. Hope this information helps. If you would like to discuss please give us a call at 732-691-6531

Sorry I must have been worn out last night. From driving all day. I forgot to mention that I have the original harness DBW pedal and TB and E40 ECM. Would like to try to mod what I have in hand. Where can I find what to remove from the harness. And yes I may decide to Go to a LS1B /411 system. But thought it might be better to stick with the E40 set up? Thanks

I was told by some of the other harness sponsors that alot of the things I wanted done with my E40 ECM and harness couldnt be done and that I was in black magic territory, when I talked to John at Speartech he made it sound like it was not problem and was as easy as brushing his teeth, he was right the harness plugged in and the engine fired on the first spin of the engine.
BLACK MAGIC indeed. That is the same way I feel. My block is a 05 GTO but the intake I got from a 06. I found a 06 harness ECM tb . But on the net I was told you can NOT MIX 05 /06 GTO. They both have 24x but the E40 ECM changed. I finaly talked to John. He laughed and said do not belive the net it will work. But i found 05 harness ECM TB & pedal much cheaper. May let him do the ECM but with 40+ years in electronics I feel I should save the $200 on harness. But can't find what to delete. Am I trying to run open loop or closed? I could start with a non mod harness. This all new to me but I am excited....

The 05/06 GTO ECM's do have different part numbers, but they will interchange I don't know if ones is better than the other or what is different and why they have different part numbers.
Myself I rather have it done by someone that definitely knows what they are doing and not have the aggravation of one person doing the ECM and a different person doing the harness, when something does not work both parties start pointing fingers and blame each other for not knowing what they are doing. My time and not needing the aggravation of shipping stuff back and forth is worth the extra cost to me.
I also like to learn, if it is something I plan on doing multiple times I will spend the time to figure it out and do it myself, but if its a one time shot I leave it to the people that have the expertise and correct tools and supplies.
