[QUOTE="Diablo1, post: 1452260, member: 91933"] I bought a spare ECU 3P6-23 on fleabay for my 2006 FJR1300 AE and sent it off to Ivan for his flash. Installed it today, did the Barbarian mod, and set CO to zero for all 4 cylinders. Bike fired right up with a cold idle of 1400 rpm. When the engine warmed up to three bars on the dash, idle settled to around 1050 rpm, about the same as it was with the old ECU 3P6-21. Ivan advises to set the idle to 1150-1250 rpm, but I kept the idle low as before so the bike wouldn’t throw a shift error code. Went out for a test ride despite a temperature of 23 F, at least the roads were dry. Bike ran very smooth and shifting was excellent. Small movements of throttle off and on were precise, and it was easy to pull away from a stop. Ivan recommends 89 octane, but my tank had 87 octane ethanol-free gas, and I couldn’t detect any pinging with the way I ride. I’ll keep running 87 octane, unless I hear some pinging in the warm weather. My bike ran well before Ivan’s flash, the only issue was the engine hunting at 3,000 rpm while steady cruising in 5th gear. I did about 30 miles today in a mix of city and highway riding and the bike was perfect. [/QUOTE]
