Author Message   Scooternerd Posted on Monday, March 08, 2010 - 07:36 am:        Bike set up with open airbox w/ breather and micron exhaust running of stock ECM. I've done quite a bit of reading and if I understand correctly the race ECM will get my peak HP at 300 less RPM. Any other advantages (mpg, torque)? With my current setup will I be looking at gaining more benefits? Or should I save the 200 on something better? Thanks.   Ratbuell Posted on Monday, March 08, 2010 - 08:41 am:        More than HP, you should be worried about LEAN. That micron flows a TON of air, and so does your open airbox. You need fuel to match. Get the ECM, you won't regret it. And, your engine will thank you.   Scooternerd Posted on Monday, March 08, 2010 - 08:57 am:        I'm sold, just needed the extra kick to commit. I have a 04 XB12R race ecm, will that work in a 06 XB12X?   Froggy Posted on Monday, March 08, 2010 - 10:30 am:        You MUST either remap or get a new ECM for the Micron. The bike is running very lean, and can damage your motor. You can find some pics in the archives of someones ruined motor from it. I bought the map for that same setup from American Sport Bike, and it runs fantastic.   Pkman Posted on Monday, March 08, 2010 - 12:14 pm:        Will the race ECM make it too rich with an open filter but the stock exhaust?   Scooternerd Posted on Monday, March 08, 2010 - 06:46 pm:        Got bike with micron installed. ECM is Y0152.3A8.05220 Is this a "micron" ecm or did he just remap stock ecm to run with micron? Will the dealership have any issues learning a race ecm w/ a micron?   Ratbuell Posted on Tuesday, March 09, 2010 - 12:10 am:        I've had my stock muffler back on with the race ECM...for a day and a half. Once the AFV relearned, it seemed to run fine. Till I snapped the belt.   Ratbuell Posted on Tuesday, March 09, 2010 - 12:10 am:        Forgot to mention - there's no muffler servo control with the race ECM, so I have the valve wired open.   Froggy Posted on Tuesday, March 09, 2010 - 12:18 am:        quote: Is this a "micron" ecm or did he just remap stock ecm to run with micron? There is no such thing as a Micron ECM. That part number is a stock ECM, whether the programming has been altered you can't say without checking it out in ECMspy.   Scooternerd Posted on Wednesday, March 10, 2010 - 01:47 pm:        Thanks all. Finally got up w/ original owner and he stated that it was remapped by American Sport Bike when purchasing Micron. Saves me some cash. So anyone need a race ECM?
