PCM Calibration
During my trip to CO last month I got a CEL with code P0170. Took the truck into the local dealer and they said they had to re calibrate the PCM to the latest release per TSB 16-0134.
My question is when they programed the PCM to the "latest" release would that include all previous TSBs that required an updated PCM cal?
I am specifically wondering about the TSB that came out for the "Jack hammering" (whatever that means) problem. Would that TSB calibration be included in the one I got?
Thanks
Curt

Yes. Flashes are cumulative. So you would have everything up to the latest. About every three years I pay to dealer to update my truck. Improvements get made, etc. They usually charge me .5 hour labor.

Ok, thanks for the info.
That might explain a couple of things I noticed after the re-flash.
I noticed about .5 mpg improvement overall after the PCM was flashed. I will now check without the trailer to see if there is any improvement there.
I use the scan gauge II to monitor the GPL and regen status. I noticed after the flash that the regen shuts off sooner than it used to. It would stop at around .9gpl previously and now it shuts off at around 1.3gpl.
