The PV3 tuner’s kit comes with everything you need to dial in an existing tune or build a custom tune from stock.  Install the included wideband module, flash the ECU with the PV3 and then use C3 software to dial in your tune.  Works on all EFI Harley Davidson models from 2002-2022*.  All diagnostic harnesses are included to work on J1850, CAN and MT22 type ECUs.

*May not work on some 2002-2004 models.  Call Dynojet to verify.
