    2016 LT1 swap, no throttle control, just idles, tune and log uploaded

    I'm sure i must be missing something. Here's the tune and a log. I have signals but no throttle, truck will start and idle but that's it. Any help would be great.

    Yes, i dont have them in front of me, will tomorrow. I think the only one i had was p2138 until i hooked up the Speedo sensor. Haven't gone through and updated the info for it because i didn't think it would affect anything. This has been an ongoing problem I've been working off/on for a week now. Ive tested all the wiring between the ECM and APP, and the ECM and throttle body all good. I'm still getting the code and don't show a signal from the ECM to the throttle body with a graphing meter. The app did get wired wrong but it reads and i thought there should be some movement of the throttle even in limp but there's nothing but idle. Wondering if it smoked the ecm with the wires wrong? Thoughts?
