80e to 60e OS segment swap??

[tinkaboutit]

OK, so the skinny is I have a 5.3/60e combo in a swapped c10. The computer is a p59 from a buddies 6.0/80e swapped truck (he went TermX).

I got the harness and ECU swapped and got the thing running and driving, but with only 2 gears. Realized the harness was pinned different for a 80e, changed it back to a 60e pinout and also changed the drop down to a 60e in the tune.
Now it has only 1 forward gear (its either stuck in 1st or 2nd)

I was trying to find a OS (1252068) to do a segment swap with, but no luck. Anyone have a 60e tune up with a OS of 1252068 or any other ideas on a solution??? I'm getting burnt out of Troubleshooting and researching, been at it all day.

Any help would be greatly appreciated!!!

The 1252068 sounds like a upgraded OS, if you click the calibration details page does it say like MAF enhanced tune or Speed density enhanced tune?

It needs to be a stock file to use the segment swapper.

On the OS tab is shows "Speed Density - 2 bar" "OS - 1252068" with an "apply code modification"

So I'm thinking my only 2 solutions would be to (1) find a complete stock 5.3/60e tune from the repository and start tuning over from scratch. OR (2) is there a best practice for changing the tune-up to a 60e other than what I have done already, which is changing the drop down from 80e to 60e and then copy pasting all the 60e tables from a stock file, or is there a better way out there????

Also wondering if I might brick the ECU if I keep changing the OS. Is there any OS's I should stay away from. The ECU is a P59 from a 2006 Silverado 2500 6.0 DBW

So more info ... If I go to the calibration details page, it shows me a OS of 1213246. However the OS tab shows a OS of 1252068. I'm assuming the first OS listed was the original and the second is the modified one?

Why not just post the .hpt file rather than having us guess?

6..23.hpl and the log of the last drive with the tune-up

That file is not OS 1252068 - it's still the stock 12613246. The OS tab is showing you what it would turn into not what it currently is, and will be blank if a custom OS has been applied.

Click the toolbar button. Or Edit > Calibration Details. Or CTRL+D.
