Does anyone know what ECM Cummins is using in their R2.8 crate motor?

What he said.

I got +74hp and +190ftlb on stock turbo running on inertia dyno. Made roughly 1300* egts and a light haze so she needs a bit more air. Large A/A FMIC.

Thanks! I'm looking to repower a Jeep Wagoneer so I'm hoping their next crate motor is in the 3.9-4.5L area. Knowing that they are using a supported ECM for the R2.8 give me hope that they will continue that trend with future crate motors.
