For a tuner to be a true "Auto Tune" tuner you need a tuner that uses 18mm closed loop 02 sensors in the exhaust. Your bike doesn't have 02 sensors so you would need to have them installed if you want a true auto tuner.
Power Vision offers a tuner without 02 sensors and a auto tuner with 18mm 02 sensors and Tundermax makes auto tuner with the 18mm 02 sensors as well.
The 18mm closed loop 02 sensors are used to monitor the AFR through the exhaust gas allowing the ECM to make real time AFR adjustments, this means you never need to worry about the AFR because the ECM will always make the correct adjustment.
Timing can not be auto tuned so timing adjustments to the base map would need to be made manually.
The PV is a piggy back tuner which is used with your stock ECM.
Thundermax tuner replaces the stock ECM with a new Thundermax ECM.
I use the Thundermax and I can access the ECM and make any adjustments needed to the AFR and timing and any other feature the ECM controls.
In most cases there is no need to dyno tune your bike if you use a auto tuner with the 18mm closed loop 02 sensors.
The Auto Tuners are more expensive than tuners that just makes adjustments to the EFI.
