Dynojet has evolved the OEM closed-loop, adaptive fuel control system on your Harley-Davidson to meet the needs of performance enthusiasts with our Target Tune module.

Dynojet’s Target Tune is an exciting product that can add a new dimension to your Harley-Davidson’s ECU. When paired with a Target Tune specific calibration flashed by a Power Vision, your ECU will run closed-loop fuel control based on wideband O2 sensors to not only determine the ideal air-to-fuel ratio for your ride in real time, but hold onto it!

The Power Vision delivered calibration changes the coding in the ECU to “understand” the wideband signal (from Target Tune) and allows the ECU to accurately achieve the target AFR.

Currently this module will only work with non-VVT Touring models.
