Default Gen V L86 - squarebody - pedal issues

Hey all, sorry I’m not much of a poster in my oldish age (37) haha.

So I have a 2018 6.2/8L90 with low miles, bought a psi harness and computers. They installed a base tune but I had to overwrite it as I added rebuild the heads, cam, dod delete etc.

anyways PatG has been supporting me with remote tuning and it holds the idle solid but still having pedal issues.

I have two pedals, one is a 05-13 corvette 6 pin and the second is the pedal from the truck. I’ve pinned out each of the wires to the ecu and can confirm my 5v ref, signal and low ref are matched to the truck pedal.

If I ease into the pedal, it will respond accordingly, if I try and give it any throttle - quickly or to fast, it will grab and hang at 5k for 2-3 seconds then slowly drop back to idle.

I thought maybe a maf/map issue and replaced them in the event they were faulty. Same issue.

I’m using a 2014+ truck base system configuration with a custom tune. I’ll have to run the codes again this week.

is there something I’m missing? Possibly wiring to my map or maf potentially not pinned properly?

couple photos, don’t be to hyper critical, still no where close to where I want it. Custom frame, 4 corner coil, truck is body dropped to sit low over the frame. Been building it the last two years.

deathbydecaf.. very nice project, I am ending work on a '86 C10 5.3 swap as well. my setup is from a '13 silverado so the computer/wiring is a little different. i was able to use the factory pedal and fuse box harnesses. i did have pedal issues, BUT... I THINK I have it figured out - wire connector problems from my splices?? are you a member/know about 67-72chevytrucks website? there is ALOT of truck info there and they cover all C10 models, not just 67-72 trucks.
anyways nice "beginning?"... and please keep us up to date on the build...

Did you contact Pat G? If he's doing the tuning I highly doubt its a tuning issue. Have him check the driver demand X and Y axis and make sure they are correct for your OS.
