Apologies as I've not been active on here recently. The 1125CR is going very well and I did a track day at Cadwell Park recently  I have the EB race ECU fitted and the bike runs well despite going back to the stock exhaust for the track (noise test). One fault though. On first revving the bike it stutters at a certain rpm point. It only does this once and then runs clear thereafter. I dropped it once at Cadwell pulling away in the park ferme when I forgot to give it a 'blip'. Any ideas what may be causing this? Peter | ||

When you change ECU's you should thereafter do a TPS reset. Your fuel maps in the race ECU may be a little rich for a stock exhaust. Did you have Erik Buell Racing match the race ECU to the stock muffler? | ||

Thank you. I have done the reset. I will try again. Yes the map is the matching one. I should have said, the problem was there with the 'Albert exhaust'. | ||

Any chance you have ECMspy? Great tool for troubleshooting. The next area of curiosity would be the Adaptive Fuel Value. You can get that from the Instrument Cluster. Then on to static voltage test (not running) and active voltage test (running at idle) with all gear energized for as near to riding as you'll see while stuck in traffic. Report back when you can. | ||

You know, now that I think about it, I'm not sure ECMspy works with the 1125's. | ||

There's an IAC Averaging procedure to run after performing the TPS Reset: simply let the bike idle for 10 mins after doing the TPS Reset. Don't know if that'll solve your problem but I'll betcha it can't hurt. | ||

with the race ecm mine always started but you had to blip the throttle before you pulled away for the first time or it would stall, since fitting my full system it was running a little lean so had another map uploaded which made it run terrible, then had another uploaded and now its mental | ||

I've done all the resets and calibrations for the umpteenth time It's just an idiosyncrasy I suppose. Thanks for the ideas. | ||

Many people in the UK report this happening with the race ecm, caused me to drop mine in a supermarket car park, very embarrassing, fixed it by changing the fuel and timing maps at the off idle areas to the stock ecm settings using Tunerpro, never missed a beat since, the info is on this site somewhere if you do a search you should find it. | ||
| Wraithwrider |
Many thanks Nearly as embarrassing as doing it in front of your track group at Cadwell I suspect. | ||

I've just spent 20 minutes searching through the forum looking for advice on how to use Tunepro to modify the EBR ECM to address this problem. The bike only stalls once and if the throttle has been blipped the issue goes away. If anyone can steer me in the right direction it would be much appreciated. I've tried all the likely candidates for search tags. Peter | ||

"They all do that Sir" - at least that seems true in the UK... Mine certainly did. I never "fixed" it as i got used to a "one blip then you're off" approach after nearly dropping it the first time. Seems mainly prevalent in UK/Euro bikes... |
