I need some help. I have a 2003 XB9R. When I first got the bike in January, I installed a race pipe. I knew this would do nothing for performance until I would open the airbox and change out the ecm. The bike ran great and sounded good as well.
I recently changed out the stock ecm with a race ecm and also added a K&N filter. I had the TPS reset by the dealer. I went out and as soon as I was 3-4 turns into "The Dragon" I knew something was wrong. I lost the pull between 3,000 and 4,000 rpm. I was very disappointed in the performance so that night I replaced the race ecm back to stock and put the stock air filter back in.
The interesting thing about this is that I had a dyno run done with the bike set up with the race ecm, k&n, and race pipe at Wheelers. The result was 79.14 hp but the torque was very flat and actually went down in the problem range before going back up to peak around 64. I also had it dyno'ed after putting it back to stock (still had race pipe). The torque curve was almost identical and the HP actually went up to 79.48hp.
My question is what the heck is going on? Anyone have some suggestions? |

Only Lost 2 runs on the dragon. We went up the skyway and the rev's stayed up over 4500 so the dead spot was below that. That night I swapped back to the stock setup and all was good.
Any idea what the issue is? |

Did you give the race ECM time to learn your bike when you installed it?
