Auto Tuner
Been reading a lot about auto tuner on this forum. Is this something you can add to an existing power comander V or is this something that replaces it. What does an auto tuner do that a power commander doesn't do?

Yes you run the auto tuner with the power commander, It uses the latest engine management technology to give you a precise air fuel ratio based on readings taken from the oxygen sensors, imap sensors, engine temp, throttle position, and a few more readings. The power commander basically runs your engine by gathering information from the throttle and it adjust the timing as well to enhance performance. I call it an electronic carburetor type system, it ignores all the other readings taking from the sensors. This is still an improvement over the stock HD system as this system uses out dated engine management technology. The power commander is more consistent in that it gives your engine a set table of adjustments based on percentages for fuel and degree of crankshaft timing for ignition timing to deliver a set amount of fuel based on throttle position, this is why running PC-V with autotuner is the ultimate engine management system in my opinion better than harleys race tuner, as the race tuner does not offer wide band heated oxygen sensors
