On 2020-2021 Dodge Charger and Challenger models equipped with the 5.7L or 6.4L Hemi, the factory PCM is locked in a way that blocks standard reprogramming. The PCM-0D-935AA is a physically modified version of that same PCM, altered by HP Tuners before shipping to remove the write-protection so the module can be tuned through VCM Editor.

HP Tuners PCM-0D-935AA Compatibility Notes:

• Matched to 2020-2021 Dodge Charger and Challenger models running either the 5.7L or 6.4L Hemi engine.
• Requires PROM installation or a computer flash to configure the module for the specific vehicle before use.
• Works with VCM Editor software for full calibration access once installed.
