We went to map my 04 600rr on a dynojet dyno yesterday. After getting the baseline with the stock map on the USB PC 3, we were using tuning link and was doing a roll on at 10% throttle, the dyno would go to target rpm at 1750 and then jump to max rpm giving 100% brake on the dyno. Any tuners had this problem at all? The Rpm i'm referring to is the reading from the powercommander not the tach on the bike. We had the wire attached to one of the wires coming off the #4 spark plug boot. The PIDS were set as powercommander reccomended so im not sure if what we need.
