    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.

    I wouldn't hold my breath on any of the new chevy stuff. If the e93 is anything like the t93 tcu it doesn't look like its happening and going to have to wait for stand alones.

    These are awesome engines. I've tuned several swaps with the engines. They make good power and awesome torque.

    Given we can't even get unlocked E90s now, this seems further away than ever unfortunately...
