hi everybody,

I am working on 2015 pickup sierra and I am facing unusual issue .
I keep trying to open engine rev limit but the ECM hold the rpm on 5800 even on driving/parking/neutral .
Anybody have idea what's going on ?

hp.450, it looks like there was an issue with the definition of that RPM limiter table, if you can please download the attachment in this post and put in to this folder.
C:\Program Files (x86)\EFILive\V7.5\Calibrations\E92

Because it was not changing the correct table when you first did this I would suggest starting again from the stock tune.

Please note, that .calz file is designed to work with the software release from May 1st 2015

Apologies for the error.

GMPX,

We update and copy your attachment to the folder and try to tune but still we are facing the same issue . Any other way to solve this issue ?

Thanks

Did the table look different when you reopened the file?
This is what it looked like for us, we also found no other instance of a 5,800 RPM limit.
