The DiabloSport Trinity T2 Modified PCM Swap Kit (PKITCHALV817-T2) pairs a DiabloSport Modified, unlocked PCM preprogrammed for the 2017 Dodge Challenger with the Trinity T2 in-cabin touch-screen tuner and monitor. Late-model Dodge vehicles ship with a locked factory PCM, so the included unlocked PCM replaces it and allows DiabloSport performance calibration, data logging, and adjustment of parameters such as spark, fuel, and speedometer tire-size correction. Disabling the factory Multi-Displacement System (MDS) is supported through custom tuning. The original PCM can be reinstalled to return the vehicle to stock.
