i have been fighting with this swap for a while now. 97 Silverado and I am putting a 2018 l83 and 6l80e. I can't find anyone having the issue I am having. I have had some gremlins and my harness builder helped me find one problem, but now I have a new problem.. The first problem the harness builder help me solve was the motor would just rev up on its on or as soon as I tapped the pedal it would just rev up. Ended up being a bad pedal. Now my new problem is when I shift to reverse it reves up and if I switch back to park or neutral it idles back down. The trans never feels like it engages forward or reverse but I don't give it long because it reves up too quick. I attached a file of the scan and you can see the prndl channel change and then the rpms shoot up. I have check grounds because I know they can cause all sorts of problems but they are good. I have several DTC;s but they are permanent and my programmer says they aren't really a problem. Any iideas would be greatly appreciated.

 

Not enough information in that file to do much other than confirm there's a problem. You have a lot of duplicate variables recorded but you're missing a lot of critical stuff, namely all of your estimated, desired and actual torques.

 

Ok Thank you for responding, can you tell me what all I need to monitor please, maybe a snapshot of what you monitor? I am new to this, but I am trying desperately to get this build done its been a nightmare.

 

This is another guy's file I helped with...he has basically everything you need.

 

Thank you for the scan. i included the channels and ran another scan, would you take a look and see what you think please. I see it thinks its in 1st on the current gear channel but the prndl status shows park, kinda of confusing

 

Also here is my tune

 

it didn't post the first time

 

Can you read faults from this thing?

 

DTC's are
P0097 Intake Air Temperature Sensor 2 Circuit low (Permanent)
P00F4 Humidity Sensor Circuit Low (Permanent)
P0113 Intake Air Temperature Sensor 1 Circuit High (Permanent)
P0691 Fan 1 Control Circuit Low (Permanent)
P182E (Permanent)
P1915 Internal Mode Switch Does not indicate Park/Neutral (P/N)During Start (Permanent)

 

Yeah you're gonna have to look into resolving those before making it much further with anything else. Sounds like the PRNDL might have a floating input. Or maybe switched out with the pedal position wires, based on that data
