Need some help from the EFI Live Community. Paul, Ross, Joe?

Oh, so you are using the 4T65E... then the ratios would be correct see post #6.

The file I posted is the one we are running on right now. I will try everything that has been suggested as soon as the weather clears.

On another note, the car comes with a traction control button just like the corvettes I usually work on. I wonder which wire that signal comes in on the E67 ECM and if it's just a ground signal? Anybody know?

Thanks everyone for the compliments. Actually this is only the third engine swap like this in the U.S. and it was my customers idea not mine. He did a ton of research and it was a very smooth swap except for this throttle blade issue. He does plan to drive the wheels off this thing after we get all the little bugs worked out.

Thanks for the suggestions and please keep them coming.

Ok so Fiero is front wheel drive and you are using the 4T65? Oops. Dyslexia getting worse :).

Normally GM runs the traction control into the BCM.

:cheers:

Ian, you have a pm... :grin:

I made a file with the table set to 8000. We'll run the file on the car as soon as the weather clears up.

Thanks.

Thanks to everyone that has made suggestions. I've made 5 different files with your names on them so I can give credit where it's due when we resolve this. Man I sure hope we don't have to bring the BCM into this to get it resolved.

FYI for those that don't know, the Fiero is a rear engine rear wheel drive GM product. We just used the Impalla SS front wheel drive engine and tranny and moved it to the rear of the Fiero. Pretty slick swap.

Thanks again guys!

Post some pics... :rockon:

One from the top and one from the bottom

I have tried everything everyone has suggested. Still having the same problem.

I have exchanged e-mails with a fellow that deals with the LS4 and Front Wheel Drive Impalla SS. He said with out a doubt our problem is that we need to turn off the "Differential Score Abuse". He went on to say that has to be turned off regardless of what else I have disabled. EFI Live has nothing called "Differential Score Abuse". Is this something like a patch that needs to be applied to the software? Can Paul help with this? I sure hate to have to purchase HP Tuner to get this customers car running. I'm lost. You guys have any more suggestions?

Thanks. That's an older picture. It looks even better now but I haven't taken any pictures lately. To focused on trying to find answers to this throttle problem.
