[QUOTE="jammess, post: 1430115, member: 89387"] Most interesting and I concur with your experience 100%. Ivan told me pretty much the same thing about the gen3 and its ECU memory. That's a plus for a gen3 not to take anything away from the gen2 after Ivan's flash. I got 51 mpg after the flash as well with the O2 sensor connected and 47 mpg with it disconnected. Ivan thinks that the ECU must be still getting some kind of input from the O2 sensor even though he has zeroed out the O2 data. If I disconnect the O2 sensor my mpg drops to 47 mpg although I can't tell any difference in performance. I did notice that with the O2 sensor connected the mpg seems to fluctuate more depending on engine loading and when riding under changing engine loads the 51 mpg soon begins to decrease and settles out around 47 to 48 mpg. I left the O2 sensor disconnected just because I don't like the beasties and 47 mpg is 4 mpg better than what I used to average so no complaints. Yup, I'm a believer in Ivan's work. [/QUOTE]
