2020-2022 Duramax 3.0L LM2 HP Tuners MPVI4 Custom Tuning
To tune an E46 with HPTuners you will need the following:
1. HPTuners MPVI device
2. An E46 unlocked ECM unlocked by HPTuners https://www.hptuners.com/product/gm-e46-ecm-service/
3. 6 Credits
4. E46 LM2 Canbus Plugs
Please make sure to provide a stock read of the GM E46 LM2 ECM.
At this time E66 is only fully supported with emissions-on tuning. Please contact OCDiesel before ordering an E66.
At least for the first while what we strongly suggest doing is first flashing the ECM without any other modifications, unplug what needs to be unplugged and road test and ensure the truck is happy. Only after that is done do the physical modifications, this gives you/us time to catch any issues that may arise and deal with them before the point of no return.
