    Any support for 2020 6.6L Gas Work Truck?

    I've got one here and will be doing a fleet of them (adding speed limiters for insurance reasons). Can't even identify the ECU.

    I'm guessing it will be $1500+ ea to be able to adjust the calibrations on them. You better be saving more than that on insurance.

    I asked this recently and they said they don't have to plans to-but we know that can change. The ECM case has E90 engraved into it-it looks just like a E90 but uit does say that it is a E93. The pinouts are a mirror image of a 1500 E90. I'm hoping I can take an unlocked E90 1500 tune and get into it since the 6.6 will come out in favour of a 427/LT4 head combo.
