Now I don't know a bunch about this ECU flashing business, but I have read just about everything on the thread.įrom what I gather on that thread it seems like people who have idle issues are supposed to go into the fuel map and adjust the fuel delivery numbers in the 500-2000rpm ranges by either making the number greater or subtracting them. He also told me that recently another customer with an 05 R1 is having the opposite issue, and that his idle is 300rpms higher than what they set it to after they flashed it.:surprise: I talked with someone from SBU yesterday and was told that 'they normally don't get this issue with my gen R6' but that they can try bumping up the target idle by like 200rpms. Valves were checked at 26k miles and my bike now sits at only 34k. cleaned TPS sensor and checked it's values in the Diag mode (16 when closed and 94 when WOT)

replaced spark plugs (even though I only had 4k miles on the ones installed) checked ignition coil resistances (all primary and secondary resistances within spec)

checked battery voltage and operation under load + charged it If I help it idle by keeping the throttle held and my bike gets up to temperatures of 180+ I can let off the throttle and my bike will act completely normal.īefore I could get in contact with SBU I tried the following: Since then when I start my bike up cold it will begin by idling at either 2k or 1.7ish, but once my bikes temp goes from Lo -> 109F the idle drops back down to 1k,then bogs out and dies. Started it back up and continued on not having to stop until I was closer to home, I pulled off to the side of the road and pulled in my clutch expecting it to happen again, and surprisingly it didn't die at all, and was back to it's normal idle. Confused I started it back up again (with a little help of the throttle) and proceeded to the next stop sign, where it died on my again. When I went to turn out of the parking lot I pulled my clutch in and my bike abruptly died. When I left I started up my bike and right away noticed that my bike was idling low, like at 1k instead of the normal 1250-1350. On Sunday I went riding with a small group of people for around 2 1/2 hours, we then stopped and grabbed something to eat. I rode it everyday without issue leading up to Sunday 4/01. The entire week that I rode it my bike felt amazing, the reduced engine braking, better throttle response that felt super smooth, all that good stuff. I got my ECU back last Monday on 3/27 and immediately got it back in my bike. ( 2006-2011 Yamaha YZF-R6 Race ECU Flash) So last month I sent my ECU in to SBU (Superbikeunlimited) to be flashed for my 2009 R6. Long time lurker, first time poster :smile:
