So i got the harness installed today and after that the dealer "updated" my flash that I thought was current.. Well now the bike runs like crap..Its wasssss running great.. Now, Its very lean. Popping and missing. Dying at red lights/stop signs.. Anyway.. Its going back in the morning to see if they can put it back like it was?
Anyone had this happen?

Did you try resetting the TPS?

Yep twice.. Nothing changed. I wish the TPS reset gave you a conformation that it worked.. I done it by the book though..

Part of the new harness is the ECM reflash to activate the relay to switch a leg of the stator on and off.

If you go into diagnostic mode, you can see the TPS settings. Mine runs from 2% at closed throttle to 100% WFO.

Good question, EBR would have to answer that, but it should just be a matter of retrofitting the harness relay programming to the Race ECM.

EBR race ECMs have the updated firmware necessary to run the stator harness. No worries

Illbuell,the new flash may have reset the AFV to 100/100, if your ecu had self adjusted previously to a different value then it may just need time to relearn.

afv(adaptive fuel value) ok I should have said 100front/100rear. The 100 means 100%,the ecu looks at the 02 in the exhaust with narrow band sensors,if it senses a lean air/fuel mixture within a certain learning area it will richen the mixture globally for each cylinder and vice-versa.The diag mode displays the current state.
Here is a post about afv.http://www.badweatherbikers.com/buell/messages/290 431/463457.html

So if I have a protune 3 and richen the mixture the ECM just leans its self back out??

Try taking it off (disconnect the ground on the protune) temporarily and see if it runs better. The latest flash seems to run very nicely for most people.

Even with the RT-5 exhaust? If its lean now wouldn't it be even leaner with the protune off? Thanks
