did a little testing and research this weekend. some of you may already have done this and figured it out for yourselves. if you are running and ebr ecm that is not configured for the stator cooling update harness and you have the harness installed, you are running only on 2 legs of power all the time. the relay when energized closes the third leg and allows full charging. | ||

I was noticing this as well. Thought it I was having a short somewhere and was gonna take it in before winter for warranty. To fix this do I have to send it back and have it configured? | ||

I'm pretty sure the Erik Buell Racing ECM is programmed for use with the harness. Send them an email and ask. The battery light in my 08 comes on more with the race ECM. I don't think it's a problem. | ||
| Froggy |
The oldest ECM's did not have the programming for the harness. Also, most of the ECMs have a lower than stock idle, and that will make it harder for the bike to stay charged in some situations. | ||

I have had the same problem as well and sent mine back with a specific mention of the issue in the box and by email. With the Erik Buell Racing ECM the battery light and eventually a System Voltage display. I put the original back in and it's all like a bad dream. Every time I put the Erik Buell Racing ECM in the battery light and eventually System Voltage display appears. I keep telling myself to hold the RPM's up but at $3.11 a gallon I really don't want to. Perhaps the new Erik Buell Racing ECM directive should be "please optimize ECM charging system for lower rpm usage". The race module is fun but discharging the battery with street riding makes it is a waste of money for me. this issue was acknowledged/mentioned by Anonymous Posted on Saturday, September 18, 2010 - 08:09 pm: "Race ECM runs the fans more, so it takes a bit more watching out for battery charge state with extended running in the low charge zone. " http://www.badweatherbikers.com/buell/messages/290 431/595414.html?1284916658 I would rather they get it right for street use than return it. | ||

It is a RACE ECM, not street. If it works fine for you on the street, than great, but it isn't intended for that. (Proud owner of two flawless Erik Buell Racing RACE ECMs.) | ||

if you have a race ecm and the wiring relay package previously installed, find out if your version of the race ecm is setup for the relay. if it isn't then you might consider removing the relay harness from in between the stator and regulator. this of course would mean you are more likely to overheat the stator | ||

I have the Erik Buell Racing race ECM and harness upgrade on my 09. I'm also using the aftermarket FH012 regulator since the original self destructed a while back. I decided to do a little testing last week to see what was going on with the charging system and specifically when one leg of the stator was disabled. I connected a digital multimeter to the battery and a LED to the relay controlling the third leg of the stator. LED on = three legs energized. I didn't have the multimeter strapped down so I just did this quick test in my driveway. Started bike, LED on, voltage = 14.2V Warmed bike, LED always on, voltage settled at 14.0V I revved the engine to get the temperature up. I managed to see a CT of 225 deg. The voltage never dropped below 14.0V and the LED never went out. If I turned on the high beam, voltage would drop to 13V but would recover to 14V at 2100 rpm. The LED never went out which surprised me. The bike was idling for about 40 minutes before I finally shut it down. The other thing that surprised me was how much the voltage on the display lagged behind the DMM. Also the display was consistently .3V higher than the DMM. I think watching the display while riding to try to diagnose anything is pretty much useless. It always bothered me that it took so long for the voltage to recover from when it was reading in the 12s but now I realize it's the display and not the charging system. I'm setting up something I can ride with so I can see what's going on on a day to day basis. Of course it's going to rain here most of the week so I won't be able to check it out until the weekend. I know this is more information than was originally discussed but I figured it would be of interest to you guys. | ||

You can see real time voltage in diagnostic mode. | ||
| Blk09r |
But you can't ride in diagnostic mode. At least I haven't been able to with my bike. | ||

Froggy - Buell race modules have been installed by dealers for street use for many, many years. This latest iteration lacks the street manners the earlier one's had. Froggy remember the cheerleaders in Hollywood Knights? | ||
| Gemini |
Blk09r, your led will stay on at idle and lower rpms. it is intened to "kill" on leg under a certin rpm range if the voltage is high enough once the engine is up to temp. so you had 2 of the 3 covered. run the same test and take your rpms up a bit higher and hold long enough, and the relay will open. | ||
| Blk09r |
Gemini - That's my plan. i want to see what is going on as I ride the bike. Now if it would stop raining... | ||
| Froggy |
I don't recall any dealers having street legal Race ECMs for sale. Are you referring to the XB P&A Race ECM that many installed on their bikes? Other than being an ECM, they have nothing in common with Erik Buell Racing's offerings.
Nope, never heard of it. Blk09r, can you post more details on your LED setup? It is something I want to do to mine just out of curiosity. | ||
| Dannybuell |
The S1 race module worked fine on the street for almost 10 years B4 it gave up. Froggy the movie Hollywood Knights? | ||

Froggy - I got a 12v LED from Radio Shack. I don't have the part# handy, but they have a few to choose from. The relay that interrupts the third leg of the stator is controlled by the ECM by switching the ground side of the relay (black wire). I connected the negative side of the LED to the black wire feeding the relay and the positive side of the LED to the gray wire (+12v from solenoid) feeding the relay. Now if the ECM breaks ground the LED will go out indicating the stator has one leg disconnected. | ||

Well I confirmed it today. With the Erik Buell Racing ecm I do run lower voltages. Whew. Now I can go back to not caring. All worried for nothing. It always starts and runs. If I wouldnt have ever looked at the volts I wouldnt have even known. I got wound up in the whirlwind of stator panic on here that I assumed that mine was failing. Seems to me, the Erik Buell Racing ecm is probably easier on the stator, with the cooler engine temps, and the third leg being turned off more often. | ||

Rpm4x4 - Do you ever have to ride into downtown Minneapolis-St Paul on a hot day in traffic? I can't ride 7 miles to downtown portland in stop and go without problems on a warm day. | ||
| Daggar |
I can ride in Modesto during summer with no problems. Way hotter than Portland.  | ||

Rpm4x4 - Do you ever have to ride into downtown Minneapolis-St Paul on a hot day in traffic? I do but I try desprately to stay out of there. The only time I ride the 1125R into the city is if there is a threat of poor weather. I have a second Buell that I ride if Im heading into the city and the weather is suppose to be nice. The XB9 is a little cooler to ride since it is a naked bike and with the heavier flywheel its easier to ride stoplight to stoplight. The 1125 is my main daily driver though. One of my days off each week also I ride the 1125R 200 miles round trip to work on my dads farm. Ive also taken it on 2 trips this year. One from Tenn down to the Florida keys and back, 2800 miles in 8 days. My second was out through Sd and back home at just over 2000 miles in 5 days. I saw 108 degrees on the cluster riding through Wall SD. I felt like I put all my gear on and started riding into the oven. LOL! 1125 handled it great though. I have just shy of 9000 miles on my 1125r this year. 100% problem free. Im loving this thing. | ||
| Dannybuell |
It sounds like the best of world's Xb for city and 1125 for the road. That will be my eventual strategy, S1 for the city and 1125 for the road. My current strategy is to run up as many 1125 miles as I can. I want to 'sort it out' before the warranty expires. | ||

I removed the harness yesterday and installed my new MOSFET regulator, I installed it where the old one was ,it is a tite fit going in but has plenty of air gap after i mounted it also used weather pack connectors so it mount and plug in and go...I used 10 gauge wiring from the stator to the regulator and from regulator to the battery.. | ||

Keef, pictures and links please. This needs to be sorted once and for all. | ||

Try riding in phoenix.... | ||

Riding in Phoenix? UGH, NO THANKS. | ||

I wish they would get the stock ECM and Charging system right...This just pisses me off. I keep the bike well over 5k most of my ride and I have major problems. So let me ask is the stock ECM and Charging system set up for the street? So much input on how the E B R ECM is for racing but yet the stock ECM and charging system isn't meant for the street whether you ride hard or not...Just fill like im ridding 10 pounds of hammered dog shit every time the the bike batt., engine and sys voltage light comes on and my bike won't start... I have had to push start my bike 2x now in public...I ride really hard there is no reason for this crap to be happening, and for you who have the E B R ECM your problem is the same as mine don't let anyone fool you! | ||
| Rpm4x4 |
1125rcya, If your having that kind of problems, you have an issue that needs to fixed. I never ride at any certain rpm, ever. My average voltages with the Erik Buell Racing ecm are lower but so is my engine temp. | ||
| Froggy |
I don't have those issues on either of my bikes, with both stock and race ECMs. Get your bike fixed. | ||

On my ride today I was seeing a high of 14.4 and it stayed around 14.2 the whole ride.This is with an early Erik Buell Racing ECM and the harness done.Maybe I've just been fortunate so far. | ||
| Keef |
I have a butt load of tandems today and tommorrow but will take some pics in the next couple days stay tuned and please be patient more to come |
