2017+ Express van 2.8

[DURAtotheMAX]

Ross, have you looked at any 2017+ diesel Express van cals? They discontinued the 6.6 dmax in the vans for 2017 model year and now use the 2.8 coupled to the 8L90 8-speed.

The main OS is 55488073.

Yes, they are quite different to the Colorado and will be a real pain to map so it hasn't happened yet. The code they run is closer to the Opel and Cruze would you believe (which also hasn't been done due to lack of enquiries).

Weird, I wonder why GM did it that way?

Is the 2.8 Express van ECM locked down like the new Cruze 1.6?

When you say locked down I'm not sure what you mean, they are still running just normal E98's with the 5 byte seed/key (but no SHA signatures like E41).
