So I did clear all updates as you said then went back and added the last update you sent thru here. Truck then accepted the tune. But after second start check engine light on as usual. Removed tune again put back to stock. Then i tried to modify stock tune with just shutting off Auto Start/Stop again second start check engine light came on with the same error as usual speed sensor. I'm really at a loss here don't know where to go from here but it definitely seems something is being overlooked with the tunes causing this error. To me seems as its something to do with the new Auto Start/Stop feature

Info File

[mikel]

OK, sorry about this. We're chasing a file processing issue.
I can fix it in a custom tune if you would like.
Load one of the tunes to the truck then post the backup and last tune written files from the tunes folder here before you return it to stock and i will post a new custom tune to load for now.


Thanks

Tune

[Jj1984]

Has the custom tune been made to fix the issue?

[mikel]

sorry again for the delay.
The issue is resolved, there was a build issue and the correct files were not making it to the database.
If you update the device now to the current revision it will work properly.
You should see ignition say loading template 172 or higher.


Thanks

Mike Mendiburo sent me a new file thru email named 2t02uq is this the corrected file? If so should I still update the device thru ignition? I installed the tune yesterday and so far no check engine

[mikel]

yes uq is correct, and is current if you update with ignition now.
