LDH, have you noticed if the autotune function does as well of a job as a dyno tune would after you go through the process?
I'm just guessing here, but I think it may actually do a better job since you would be tuning based on your normal riding and seasonal climate, rather than possibly getting a dyno tune done on the most humid or hottest (or coldest) day at the shop or track. Also, would you then re-tune your bike for summer temps if you had installed the system in the cold? Oh, and if you are inserting a sensor into the exhaust, would there be any adverse readings because of the different airflow in the pipes? (going past a sensor)
I don't have a Power Commander yet for my bike. I was going to get the PCV but wasn't sure about buying the autotune portion.
