HOW DOES TARGET TUNE AUTOTUNE PROCESS WORK?

Utilizing the Target Tune AFR data and other data from the H-D OEM data bus, the Power Vision can automatically fix the deviation between the AFR or Lambda as defined in the fuel table of your calibration and the actual AFR or Lambda by adjusting the VE tables. The data is learned in real time, but processing the data and adjusting the tune is done in an "offline state" (key on/engine off). After the data is collected, the Power Vision can process the data, correct the tune, and then re-flash the corrected tune into the ECM. You’ve effectively corrected the VE tables to ensure the AFR or Lambda you ask for (in your calibration) is what you get (as measured by the wideband O2 sensors). Once you exit the Autotune mode you’ll be back to using your full-time, Target Tune closed loop calibration.
