I read this with some interest. I assure you that Harley ecu's are not locked, they even sell their own tool to tune them. The Screamin Eagle (barking budgee) tuner, Power vision is nothing like a power commander and in fact is a very good tool for ecu tuning, better in my view than the Screamin eagle tool or any other harley tool I have used so far.certainly not superficial at all. If power vision (Dyno-jet made) did one for a rocket that would be fantastic. I have done quite a lot of rockets, to do one in an hour your guy must be an absolute fuc$ing legend, or not doing a complete tune. It takes me almost half an hour to set the bike up on the dyno and hook up data etc. Fuel and ignition.proper full tune in an hour NO way Hose A. Why you guys are having trouble getting some one to use ( what is a very basic software) Tune ECU well is hard to work out. As a reason to why a lot of folk use a power commander, I reckon it is because of the automated "Tuning Link" software. It makes it easy to get the fuelling good. Having said that I stopped using it about 8 yrs ago, got tired of payiong the same exorbitant lease fee for 12 yr old software. I then found tuning the bikes manually I was getting a BETTER result any how.
