Default Swap electronic throttle for cable?

Hey everybody! How much of a pain in the **** would it be for me to swap my electronic throttle body for a cable style one off of like say... an 04 GTO. Any more info would be appreciated.

All you have to do is reconcile the TAC module and PCM not communicating properly.....and you are set......

No kidding. I don't think it's possible without a custom PCM. The Throttle position and accelerator position goes directly to the TAC, comparison is made...and the communication between the PCM and TAC takes place via the class 2 serial buss.

It's going to be a lot easier if you install paddle shifters first, then it will be much easier to install the throttle body.....

Use EFILive or HPTuners to change DTC setting so that P1516 (TAC Module) Is Not Reported. Might also need to disable P2135 (TPS 1-2 Correlation).

Ok, I found it. Alot of old hot rod truck builders are doing this and they told me that the guys at Painless have a kit that they will send me. Otherwise they told me to go to a junkyard and pull all the stuff off of an 04 GTO and use it. I think I'll just order the stuff from Painless. I'll keep you guys updated.

I have to be honest here....

This is the most retarded thing I've heard here in a while. Why would you want to get rid of the factory system when it's perfectly reliable, and you can tune it to perfection if you were an hptuners geek?

This isn't Toyota, this is a Corvette.

So you're going to improve on the $millions that GM has spent creating the system that throttles your C5..

We run the cable operated throttle body on our C5 race car. We run a f-body pcm and no bcm. Of course we don't run ABS, TC or anything like that.

Because I'm sure the PCM would be none to happy when it tried to engage one of these features and cut the throttle, but can't because it's no longer electronic.

Is this your ONLY reason? If it is WHY?

How does the painless harness correct the class 2 serial input to the PCM from the TAC...and vice versa?

Another cobbed up car that will be foisted off on an unsuspecting buyer in the future.
