I did talk to the shop that did it, the tuner is well known around here and supposed to be very good. If it was right in the first place fixing it would be very easy, they pretty much told me to...

Finally getting some time and money to put everything back together. Looking at the logs any idea what could have happened to make it run bad? I found out some more information about the tuner and...

Well it looks like I found the old supercharged E85 tune....... Apparently something was done. Looking like a good time to start completely over......:banghead:

It was supposedly retuned for 93 and that is what is in it. Before I went for a drive I drained the fuel and put in fresh 93. I contacted the dyno shop that swapped the tune back to NA and 93 (or...

Thanks for the info, I don't have a problem with sd. I was afraid it wasn't right, I saw the stft like you did and knew that was an issue. I can't figure out how it seemed to be running right for a...

Yes, was supercharged on E85. Had to sell supercharger and later ended up swapping to trick flow heads and a Fast 92 intake. I am beating myself up for not looking over the tune after it was redone...

I have a 98 vette that i changed to an 01 ECM. I don't drive it much and something has went wrong, it will bog and not accelerate. Since it started doing this I checked for trouble codes and had one...

Are you sure the handhelds will do the trucks? Everything I have found for the ecoboost does not include the trucks.

Why wouldnt you change stoich? I Did on mine and it fired right up and idled fine. I have not driven it yet but for startup it is just fine.

Bill? any ideas?

My post asking about the truck is a separate issue. This is a 03 truck that came with a V6. Now it has a 6.0 from a express van. The fuel guage kinda works, it is just backwards empty is full and...

Are you saying download those from the repository? I sure dont want to license another file, I have already done both of those.

Thanks this info helps, it means I have another problem but I will take any progress I can get. The BCM is compatible with either the 99 or 01 OS. I think I may have a dead or intermittent sender or...

They are posted above or should i email them to support?

Here are the files if it helps anyone or anyone has any suggestions. This is the 99 ECM that I use.

I have a 98 C5 that I have upgraded the ECM to an 01. It is my understanding that to get my fuel guage to work properly I need to do a segment swap. Can anyone help?
Thanks

I understand that completely, one solution I have seen some vendors use is an option at checkout. I ended up catching the mail man driving by and he actually let me follow him to the post office to...

:(I hope it is a good book, I ordered it and USPS sucks here. They left a note it was at the post office so I went there to pick it up. They didnt have it, they said the carrier must have it still....
