The DiabloSport inTune i3 with Modified PCM kit pairs a DiabloSport Modified (unlocked) PCM for the 2021-2023 Jeep Wrangler 3.6L with a DiabloSport inTune i3 handheld programmer. The modified PCM ships pre-loaded with DiabloSport performance calibration and supports CMR custom tuning, so power can be added now and custom tunes dialed in later as other modifications are installed. The inTune i3 reads and stores the factory calibration before the modified PCM is fitted, following the instructions included with the kit. On 2021 and newer vehicles the stock calibration must be saved with the tuning device before the original PCM is removed.
