so little back story, I have a 2008 5.7 ram that has been bored and stroked to a 392 and I am running a 4L80 with a full manual vale body, nothing from the computer is hooked to the trans and has been that way since day one.
the truck was built in 2017 and tuned then had a minor retune in late 2018 after some upgrades. the truck was driven for 2019 with no issues and nothing was touched while it was stored over the 2019-2020 winter months.
the truck was pulled back out earlier this spring and I decided to clear some check engine lights after the first couple drives that were related to the transmission no longer being a 545RFE.
I did my normal plug everything in and updated my software from 4.0.12 to 4.6xx. After flashing the computer clearing the codes causing a MIL I no longer have any throttle pedal, I went back to the old tune file I have been using since 2018 but the issue is still there.
I can watch the pedal % go up in the scanner and I can watch the throttle body move from start up and go down in % as it warms up till it reached normal operating temperature idle. However the accelerator pedal V remains at 0 and the throttle position sensor sits at 0 no matter what i push the pedal to.
My tuner and I did have this issue when the truck was first built how ever I had fixed it by changing the selection in the trans choices by disable all and enable 4 speed automatic.
Ive opened 2 tickets with HP, one said its a tuning issue and they cant offer any help the other said it will be sent to the programming department and will no longer reply or give some assistance.
I do feel this is a software issue however I have read some stories about tunes being "altered" when opening in a newer software and causing some issues but I dont even know where to start, I have very minimal tuning experience, so I'm keeping my options open with this being a tuning problem
I have gone through all the trans choices available and the issue remains no matter what I choose, but that's about as far as I've gotten.
I cant help but reiterate this truck was running fine for 2 years and was running and driving before I updated the software and attempted to clear the codes.
Is someone able to take a look over this file and see if there is something that could be causing my dead pedal?
I have called a few shops trying to figure this out and there is one in particular having this same issue with newer software that they have yet to find out why
