Mike,I can't tell you how much I appreciate you taking the time to talk with me on the phone. That's amazing customer service considering how busy you are and just getting back from OOT! As we discussed, I retarded the timing a little in the areas of concern. Now I just have rare spotty knock retard <= 3 degrees. I looked closely at the F/R VE tables and "mapped" the O2 bias voltage in the closed loop area accordingly. For a big bike with a big guy on it, this thing is a rocket! I am really not able to ride it hard enough to truelly appreciate just how potent it is. I may do one quick dyno run next month just to see - I am guessing close to 80/100. The only nagging concern I have before I go blasting kudos on all the forums is head temp. I noticed that after test riding pretty hard, when I stopped at idle to disconnect me - backpack - computer - wires, temp was up to 269. What do you think?
