The double post was unintentional . . . When the bike is tuned on the dyno, what's the process? How do thye know what the new map should be, etc.?
The dyno has a sniffer they use to measure the Air Fuel Ratio. A good tuner will tune the bike at each throttle position, at every 500 RPM to make sure it is dead on. (this requires a brake dyno.)The whole process takes a 2-4 hours depending on how close the bike was to begin with. You'll be impressed with the throttle response as well as the way the bike runs afterward. Best money I have spent on this motor so far.

". . . your engine light staying on for 5 seconds indicates there is a history code in the pcm but it is not current." Can you explain this in more detail. I don't understand.
