2007 tahoe truck norris check engine light

[Julian1948283]

I have a 2007 Tahoe 5.3 that we did a dod delete and installed a BTR truck norris cam. I accidentally saved over my stock tune, I now have a P0606 code that comes on and the truck goes into limp mode. I have raised the idle rpm and changed the air settings at idle. I would appreciate any help with this thanks

'Base' should be the file from the last time you downloaded the tune from the ECM. Open in new editor, then save with a new name.

I did not know that. Had to check it out myself. Thanks Squirrel.

Electronic throttle settings most likely

Are you not able to see my post or something?

I saw your post but mine is blank, there is nothing there

Then this statement is untrue:

If you'd read the file out of the PCM, saved it, made a change and saved that, then the history would show the previous version, or however many previous versions back to the last time you read and saved the file straight out of the PCM.

If your changelog is blank, that means the only file you have has had no changes since the last time you read the PCM. Which is not what you said happened.

Thanks Blind squirrel. I got the P0606 to clear by putting the stock tune back in. I have an issue where the vehicle will crank but not start unless you press the gas pedal about 1/4 of the way down. I was also wondering if there is a way to increase the misfire monitoring. Any help would be greatly appreciated.

Trying to follow a Gen 3 idle tuning guide on a Gen 4 E38 (he posted in the wrong section) is unlikely to lead to anything good.
