CMD Exhaust brake memory cax

[Yaboy131]

Is it possible to do exhaust brake memory feature on the 10-12 Cummins?

[got boost?]

Prolly you want it done? I'd need the OS you're using to check and see

[Yaboy131]

52120818 is the CSP5 OS I’m currently using

[got boost?]

yeah I'm pretty sure I have that ecfg I can't pm for some reason, shoot me a pm and I'll get ya a quote on it

[got boost?]

what's up with not being able to pm ppl anyhow????

[Jim P]

Doesn’t work on the CMD calibrations

[got boost?]

dang, thx Jim, I hardly mess with stuff earlier than 5th gens these days.

[Jim P]

Think might be something in code for exhaust brake memory, not sure. I looked at it before compared to a 2018 calibration and there was a little bit of difference in the code.

[Jim P]

I haven’t really touched anything in the tuning world for almost the last year, just haven’t had the time for it unfortunately

[Jim P]

Only thing that brought me back here was a message I received asking if I have an SOTF file for a 2021

Entirely unrelated but I’ve figured out how to get the bootloader code from the ecm
