Is anyone finding out the new Pete's show going 65 but only going 62? WE have 2 and it's going to the shop tonight to get reprogramed.[/QUOTE
Pull fuse-B5, K17 and K18, and close doors, cluster will say "loss of communication" leave doors shut until cluster goes dark. Open door, reinstall fuses. This is a CECU reset and usually corrects issues like your having. Also usually corrects loss of das lights, guage issues or loss of window power, its first step to try for any weird cab related issues.
Yeeeees, the “droop”, as they call, it SUCKS out loud!! Dropping back to 63mph before the damn thing will take fuel again sucks...not to mention it kills whatever little momentum you had before hitting a hill!!In my Pete it's set up that if I hit 66 it's right back down to 63 and starts climbing back up. Damn thing loves 64mph. Here in the mountain states we asked for more torque to pull the hills ( I know that's a joke to have FedEx listen) now this Pete has no pulling power.
This may happen at some/most shops but our shop refuses to power spec anything!! According to our mechanics, “most of Cummings updates don’t have anything to do with our equipment and they usually do more harm than good” so they just refuse to do it. We have to go to other shops and beg them to do it for us!!Every PM all tractors are PowerSpec'd, so whatever(if any) changes the company, Cummins, can be made.
