Description
Enhanced Performance Control. The Diablosport Modified PCM unlocks the performance potential of your vehicle’s engine management system. This upgraded powertrain control module requires a compatible DiabloSport tuning device to install performance tunes, enabling precise engine calibration and improved power output with minimal downtime.
Build Quality and Materials. Manufactured with a durable ABS plastic body, this PCM is professionally unlocked and programmed specifically for the compatible vehicle models. The unit does not feature any built-in display.
