encountered something strange yesterday while de-winterizing my 961 in preparation for the Spring. I started the bike for the first time since replacing the battery last December. The thing actually started on the first stab at the starter, rev-ed to 2000, then back to 1500, then down to 1200 automatically, and set a strong idle. I was shocked! The bike never, NEVER behaved this way in the 4 years that I have owned it. I had always taken me at least 3 tries to get it started, and then some throttle to prevent it from dying. Then a little more throttle for 30 seconds to get a weak idle. That was my drill for 4 years, and the reason that I wanted a Power Commander.
Now I have to see if this new attitude that the ECU has is permanent. I don’t know for sure why all of a sudden the ECU/EFI seems to work as it should have originally, but I suspect it probably has something to do with the battery replacement. I believe it was the first time the ECU on the bike was completely powered down since I purchased it.
Could removing and replacing the battery have forced the ECU to reboot and into a full adapt/re-adapt mode and automatically resolve any issues that were preventing the EFI system from fueling the bike properly?
