2010 Freightliner 6.7 Cummins demandate – Need Help with Tuning Process

[cp99]

Hi all,

I have a 2010 6.7L Cummins with DPF and EGR still intact. It's started throwing emission codes, and since the truck is used strictly off-road, I’ve decided to demandate it.

On the mechanical side, I’m confident I can handle the straight pipe install, EGR removal, and coolant line rerouting. It’s the tuning aspect I’m not sure how to approach.

I’ve asked around for delete tuning, but after doing a lot of reading — especially here and on Rawze’s comments— I’m realizing that:

Some tuners refuse to share the calibration for future repairs
Others won’t explain how the process is done or whether it’s done correctly
Because of that, I’ve decided to try handling the tuning part myself.

Here’s what I have and what I know:

• I have an INLINE 6 adapter and have used Insite in the past for diagnostics and minor repairs
• The ECM is CM2150, ISB220. Calibration is BAD, with ECM code of AU90050.
• I’m aware I might need Calterm, along with the correct .ecfg or .e2m files for my calibration. But I don't have them and not sure where to get it.
• I’ll also likely need help or tutorials to understand how to change the right parameters
• This is a weekend project for me, so I plan to take an incremental approach — starting with the DPF delete first, then tackling the EGR.
  

Can anyone point me in the right direction for the tuning/delete process? Also, where can I find the software and files necessary to do this properly?

Appreciate any help — thanks in advance.
