GM E90/E93 ECM Upgraded PCM Purchase

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.
