Edge Pulsar LT 17-22 GM 2.8L Colorado/Canyon Duramax

So you've made some changes to your truck and you need to update your ECM but don't want to void your warranty? The Pulsar LT is an in-line module for 2017-2022 Chevrolet Colorado and GMC Canyon 2.8L Duramax that offers complete adjustability of many features, all from your steering wheel controls. Without modifying your truck's ECM, Pulsar LT offers you the ability to adjust throttle response, manual DPF regen, trans relearn, calibrate tire size, gear ratio, TPMS, and the ability to clear engine codes. It connects directly to the vehicle computer system, making installation a breeze and leaving your factory warranty intact.

IMPORTANT NOTE - When physically changing ring and pinion gears in the late model GM trucks, the factory cruise control will be disabled. While the Pulsar will allow you to recalibrate the speedometer for that gear change, it will not re-activate the disabled cruise control system. GM has this feature laced into the engine calibration files and would require full ECM tuning to enable cruise again.
