ZackTuned along with our partners at HP Tuners, exclusively presents our E90 (L84/L87)  ECM Services for the following vehicles:

  • E90 ECM: 2019-2022 Chevrolet Silverado & GMC Sierra, 5.3L & 6.2L V8 (L84/L87) (pre-facelift trucks) (non-Global B)

    Upgrade your original E90 ECM by sending it to HPTuners. We will upgrade your original ECM so it’s ready to accept tunes, and then we’ll send it back. After upgrading, you’ll have full access to calibrate, log, and scan via the OBDII port. This option takes at least 3 business days to complete (not including shipping times).

What are credits?

ZackTuned RTD+ uses a credit-based licensing system. Credits are used as currency to purchase licenses for a vehicle's different Electronic control modules. Licensing a module gives you the ability to tune it.

The number of credits necessary to buy a license varies depending on the car. Many vehicles are two credits for licensing the ECM/PCM and may have additional options such as a TCM, FICM, or CCM.

You can find a complete list of supported vehicles and credit costs on our supported vehicle page.
