Keep in mind that a custom tune on a dyno would be worth about the same as the sensor unit. And you'll only need to buy the sensor once. As opposed to getting a new dyno every time you change engine parts. I usually tell my customers to get everything they plan on doing all at once to avoid having to dyno or rejet multiple times. It means I don't get to make the $$$ on a couple of extra dyno's, but I can make that up because they'll come back for other services.The price tag is a definite detractor. The Bazzaz unit is about $339 and the Sensor needed for the self tuning is about $312. That is about twice the cost of the PCIII. Personally I want the Bazzaz unit. The unit without the sensor is about the same cost as the PCIII. There is a write up about the traction control module that you can also buy in this months Sport Rider.
This really makes me feel better about the Bazzaz....got mine for free but i just wanted the unit and the A/F self mapper so i didnt need a dyno!! works great!! i took mine to a friend at HMF and they didnt have to do a thing, it works great, just hit self tune go beat it up on the street, see the changes it wants and boom done! retail the bazzaz is more the PC3 but if u no someone, the unit will cost $290ish and the A/F computer with O2 bung will be about $280 plus tax if they make u pay.
so $290 is about the same as PC3 and $280 is gona be about the same as a custom dyno tune BUT u can cumstom tune everyday, different weather, hot, cold, rain, dry ect!! AND everytime you up grade a part
