Edge Insight+ Kit with ECM TCM Unlock and A-Pillar Mount for 2020-2023 Silverado and Sierra HD 6.6L L5P Duramax - 84140-1

The Edge Insight+ kit 84140-1 takes a locked 2020-2023 Chevrolet Silverado or GMC Sierra 2500HD or 3500HD with the 6.6L L5P Duramax to custom-tuned with a gauge display on the pillar. It includes the Insight CTS3 monitor with the custom tuning license preloaded, the locksmith tool and harnesses to unlock both the ECM and TCM, and the vehicle-specific A-pillar mount.

Once unlocked, you back up the stock files and flash calibrations from an approved third-party tuner through the Insight+. The rest of the time it is a 5 inch monitor with EGT, regen cycles, transmission temperature, boost and more. Tunes are not included; they come from your tuner. The license is tied to one VIN, so we will need the VIN before the kit ships.

Installation and limitations

Unlock the ECM and TCM once with the locksmith and harnesses, then read and save the stock files with the Insight+ and load the calibration from your tuner. Mount the display on the pillar. Keep the 98108 ECM connector repair kit handy; the factory connector sliders break easily during the unlock. Emissions-defeat calibrations are not supported. Not for use in California.

Frequently asked questions

Does it come with tunes?

No. It includes the unlock hardware and the license to flash. The tune files come from your chosen tuner.

Do I have to remove the ECM to unlock it?

The locksmith connects to the modules through the supplied harnesses. Follow the instructions; the ECM connector sliders are brittle, which is why we suggest the 98108 repair kit.

Does this unlock the transmission too?

Yes. The 84140-1 includes both ECM and TCM unlock for the 2020-2023 trucks.

Will it work on a 2024 L5P?

No. Coverage is 2020-2023. For 2024-2026 the Edge EZ 20202 adds power without unlocking.
