Most of that time will be spent wiring up the autotune modules and then getting the modules/wiring all properly tucked away. You need to run the cable for the front O2 sensor under your tank, so you'll be messing around with that a bit.

On my bike, the rear O2 sensor gave me fits getting it out. I ultimately needed to take the entire exhaust system off my bike so I could take the header pipe to a muffler shop to get the sensor bung fixed. So I wound up spending about 4 hours over 2 days getting mine all set up and working properly.

The good news is the bike runs great. The autotune suggests trim settings to the initial map, and as you accept them, the changes gradually become less and less.

I think the best running bike is always going to be one that has been professionally dyno tuned by a competant technician, but I think this is probably second best.



Tough to diagnose without a little more info. Are you decelerating hard? Have you double checked your throttle calibration? Try taking the PC out of the loop for a short while and see if it still does it.
