I've know it's been covered on other threads, but before I throw down $250 for a Erik Buell Racing ecm to solve the engine light code "F-R AF SYS ERR", is this the cure?!? I thought I'd find out if it will indeed solve the code/engine light issue (I know, I know, opinions are like belly buttons and a$$h*les, every bodies got one!! LOL)but this is the best place to get critical info! Fact: 2008 1125R, I've installed a Barkers exhaust system and K & N air filter, I've been running it with stock ecm for 'bout 2K miles with no issues / codes. Suddenly the engine light comes on and stays on. Couple times it's off until the engine warms up to temp but it turns one as soon as it's hot. The question is: will the code be "fixed" by Erik Buell Racing ecm for said set up? Do I need to "de-noid" the thing (whatever that is!)what's the solution? The "dualbuells" may be down to one Buell, a friend rode my CR and crashed it 2 miles from my house, insurance is talking total, but I may have them talked into repairing it. The dealer I got a quote for repairs added the main Frame and swing-arm to be replaced, both with small scratches on them, they told me they are required by "law" to repair to "like new condition" unless other-wise specified by insurance company/customer, we'll see what happens!.....sorry off subject Thxs in advance for help.

Yes the ECM will fix it. The pipe is the cause of your issue, so proper mapping will resolve it. No need to denoid. | ||
| Dannybuell |
I had the same setup and problem. The Erik Buell Racing ECM did the job and took care of that. | ||
| Dualbuells |
Ok, just ordered the Erik Buell Racing ECM, Thx's for the input. | ||
| Rt_performance |
yes it fixes it the front clinder is lean will run like a whole differnt Bike | ||

I ran a Barker with the stock ECM for a couple thousand miles with no codes. The F R AFR error means that the front and rear air fuel ratios are "too far" apart. That would strike me as a fuel problem--maybe an injector not squirting enough fuel into a cylinder. What makes you guys think that the eb r ECM would fix that aside from just ignoring the AFR disparity and therefore not throwing a code? | ||

If you look at the actual AFV when it throws the code, the spread will be at least 25% apart. Put your stock pipe back on, run it for a while and the code will go away. Check the AFV again with the stock exhaust on it. I'd bet even $$ on it being either 100/100 or fairly close to it, depending on where it was originally with the stock pipe. If your pipe went to 105/95 or something like that in stock trim, that's what it will go back to with the stock ecm. Just buy the race ecm. It's well worth the $$. Forgot to add, the AFV is Adaptive Fuel Value, not air fuel ratio. The ecm is either adding or subtracting fuel globally and cannot compensate for that much of a change, thus the error.

It happened to me just last month stock ECM with a Barker and on a warm day running country roads CEL light, P1047.... Everyone told me the same thing. I bought the Erik Buell Racing ECM. Warm days and all and NO more CEL light. | ||

Okay, new ECM installed, I performed the TPS now a few times and the throttle seems to be really quirky. How sensitive to the one second on / off throttle is the tps reset? I am really going to have to get used to the non engine breaking with the new ecm. It seems the idle is really low, I have to give it lots of throttle to start off in 1st gear, I've stalled it way to many times, that is scary trying to pulling into the flow of traffic. Dumb question, I have the quite core in on the Barker is there any negative influence with the new ecm? I hope this things smooths out after a while or I relearn how to ride this beast, it seems way to quirky on the throttle, it seems to like the high rev's. Does this sound like I need to redo the tps zeroing. | ||
| Froggy |
Check in diagnostic mode that you did the TPS reset correctly, the TPS percentage should smoothly go from 2-100% as you twist the wick. It sounds like your setting is way out of wack. | ||
| Dualbuells |
Holy Crap load of error's !!! TPS: P0122 Fuel Pump: P0628 Fuel PR: P0193 IAC: P0511 Tip over: P1152 ACT INT: P----- IAT: P0113 RT FAN: P0691 All these after I did the reset again, the live data on the TPS is as you said 2 - 100%. I ran it for a minute, it was mis-firing, backfiring, all around sounded like shit then shut itself off. What do, try again, this can't be that difficult! | ||

CHECK TO SEE if on the ecm if both plugs are seated in their sockets, I dont have a wiring diagram with me but my gut is that these signals come into a connector on the ecm other possible is perhaps a ground issue | ||
| Froggy |
Ignore the errors, they are historical codes due to the flashing process, they will eventually clear themselves out. Will it idle at all? You should let it idle a few minutes, this will let the bike adjust for your IAC. | ||
| D_adams |
Multiple errors is normal from the flash. I think the historic count is 50 and it will clear out. | ||
| Dualbuells |
I did the reset, it seems to be running a little smoother than before. I'll take her out of a shake down and see how it goes. | ||
| Zac4mac |
Frank, Dean - wasn't it 10 minutes idle to set IAC? 50 CLEAN(no errors) starts and the historics clear. Ignore the historics, as Froggy said, they are from flashing the ECM. Mine was a very early ECM for "open intake/exhaust" and it was pure "plug-n-play", didn't even disconnect the battery. You should acclimate to the reduced engine braking, just downshift 2 gears sooner, you've got 6 to play with. Z | ||
| D_adams |
Yes, it's 10 minutes to average out the IAC. | ||
| Dualbuells |
I think I'll need to reset again, it didn't smooth out much during my ride yesterday afternoon. I did the tps reset before I rode it and did the 10 minute engine at idle for the average IAC. It seems to run cooler but the fans run frequently. So far the throttle response is sluggish at best, nothing even close to the original ecm. I've checked the connections all is buttoned up tight, this really can't be this difficult, I truly thought it was a plug and play. So off I go to reset tps and the 10 min. IAC average. | ||

I have had to switch back to the OEM ecm for urban riding to keep the electrics alive. Using the OEM ecm and a Barker has the CEL running continuously. The P1047 codes show front running 20% rich. I accidentally overfilled my bike today and with the charcoal can in place it still left a puddle. When I started it was running on one cylinder until it cleared itself. That has never happened before! Knowing plugged charcoal cans can cause trouble I decided that this may be the culprit. I took it out and it was really hard to blow into the charcoal can's nipple port for the tank. Also knowing that the front throttle body has the vacuum port for the charcoal can I concluded that it might make be making the front run rich. I needed to test this idea so I took the charcoal can out and extended the tank vent line similar to the OEM drain. I plugged the vacuum port and went for a short ride to lunch. The CEL went on after two minutes. On the ride back same thing, CEL on after a minute or so but this time on the way back it turned off! That was different!!! When I took my second ride this evening same thing CEL on but it eventually went off. Am I training the ECM? Did taking the charcoal can off help? It seems like it might have, the CEL is going off now. I am going to ride it like this for another day or so and see what happens. Any ideas??? edited to rename the part properly, the correct part is the charcoal cannister. (Message edited by dannybuell on July 24, 2011) | ||

You apparently have the only Buell on this planet with an EGR. | ||
| Dannybuell |
OMG! A charcoal cannister, SORRY. My bad. | ||
| Dualbuells |
Well, I must have a problem not previously encountered after countless resets, the live data shows the tps to be operating @ 2 - 100% on throttle and performing the IAC average. The bike runs like crap, firing on one cylinder, bogs down under throttle input etc.. I'm switching back to the OEM ecm until I can get contact with Erik Buell Racing people for help in diagnosing the problem. I sure hope they can solve the problem. | ||
| Froggy |
Dualbuells, I am sorry to hear about your troubles, but what you are experiencing is not normal. Good news though is that Erik and the gang will take care of you and get it straightened out, whatever it is. | ||
| Dirty_john |
gents, when I bought my Erik Buell Racing race ecm when they first came out I was informed that the ECM will reset the AFR to 100/100 every time the ignition is turned on, your problem sounds like a sticking injector, additionally the error codes in the Erik Buell Racing race ECM come from their set up process and can be ignored and will clear to historic after 50 ignition switch cycles (Message edited by Dirty_john on July 25, 2011) | ||
| Dualbuells |
I've contacted Erik Buell Racing and given them the codes from the original ECM and the new unit. They said once they had all the codes they'll be able to determine the problem. I'll keep ya posted on what they determine. Thanks for all the input. | ||
| Thefleshrocket |
Is your bike running better with the stock ECM? | ||
| Dualbuells |
Well it looks as though I may have a faulty fuel pump. The gang @ Erik Buell Racing wants the live data info off the ecm. So after work I'll run it and send them the info they requested. It's great to know the Erik Buell Racing gang has our backs on this stuff. I was reading over the manual to see how difficult it is to replace the fuel pump. Looks like you need a couple special tools for the replacement. I guess that means a trip to HD for service, sucks that none of them care to do the work, at least here above the 45th Parallel in northern Michigan!! | ||
| Dualbuells |
Fleshrocket - I have the OEM ecm reinstalled, it seems to run fine while it sets idling. I'm not sure I want to get stranded on the side of the road if the fuel pump is bad. Once I run the codes in Live Data format I hope the gang at Erik Buell Racing can give me the low down. It's tough when the two 1125"s I own I can't ride....leaves having to roll out the HD Road King Custom, a major let down! | ||
| Froggy |
They are called a pair of flathead screwdrivers.  Service manual calls for removing the swingarm, but if its anything like the XB you can cheat and disconnect the shock and jack it as far as you can, it still is a tight fit but doable. If you are still under warranty I would have them do it. | ||
| Dualbuells |
I do have the extended warranty on it, so I will take it in. Just have to grin and bare the 150 mile round trip to the HD/Buell dealer. Since I'm @ 12000 miles, I hope they can do the valve clearance check when they have it. | ||
| Zac4mac |
I'm going to be doing this very soon. Loretta's fuel pump is dying. Diagnostic Mode shows 75-100 kPa key on - motor off; supposed to be ~ 517 kPa. Start the motor and I see ~ 400 kPa, book says 380-415 is good. Same symptoms as the last time the pump went...  Zack |
