Thanks Fresno, I emailed them asking about running the race ecm with stock exhaust and they said the benefits wouldn't be great. I might give it a try anyway knowing they will reflash it for $25 if I decided to buy an exhaust in the future. | ||

Thanks Fresno thank Ponti1. He posted that originally, I just copied so people knew what the hell I was referring to. Thank you for the info from EBR. We should try to post EBR email responses here so we don't inundate them. | ||

Order placed Monday for the race ecm, just got UPS delivery conformation. Its waiting for me at home! That was quick!  | ||
| Fresnobuell |
CHEVY--you still have the stock exhaust in your profile pic? You ordered the race gas ECM...did you get that straightened out? | ||
| Justa4banger |
Well i got the pump gas version and my BAS is still functional, the shifter interrupt is wired to the kick stand switch we don;t have.. i'm sure this will be the standard... SO Monday baseline, Tues installation begins, Maybe wed or Thurs for dyno results.. of course this is all ending a date with the dyno, but i have several to choose from so it shouldn't be difficult.. Time see what this bad boy can do!! | ||

Hey so what are your guys's AFV's after the race ECM? Jake | ||
| Mountainstorm |
100 100  | ||
| Mikezx9r |
WHen you guys say the kickstand switch, is that the one that would shut the bike off if its in gear, the kickstand is down and the clutch lever is released? | ||
| Blazin_buell |
Hey Mountain, I didn't recall you saying that you reset your afv. Did it do it automatically once you plugged it in? | ||
| Dirty_john |
I am in the process of ordering my pump gas race ecu for use here in the UK, we do have kickstand switches so I have e:maiiled EBR so get an idea of what I need to do to counteract any problems - summer will soon be here - safe riding | ||

Fresno, I ordered the 08AZ, I was billed for the 08AZ but the number on the ecm is the 10AZ. So ????? I guess? Never got a response back from my email. Put the ecm on last night and it still runs so that's good, could not get the bike through all the snow to the road to ride it. Exhaust is still stock except for the single 2.5 inch tip. Buell race pipe is next! | ||

Stuff like Error Codes (Historical) or AFV are in the ECM. When I plugged the OEM unit back in the AFV was back to 105F 94.5R. Stuff like mileage, time, tripmeter are all in the cluster and do not change. I've ridden a couple of hundred miles now and the AFV has not changed. Either it is locked or it's perfect for the bike. | ||

Does anyone know (or have tried) if you can access the EBR Race ECM via ECM spy? | ||
| Fresnobuell |
When is the last time someone rec'd an email back from EBR? It's been a 2-3 days without a response from EBR. | ||

Yesterday , from Michael Richter | ||
| Toysgarage |
yeah not easy to get though to them im in australia , trying to order mine ...with no luck | ||
| Thurstonbuell |
Im sure they're busy , but Im sure they'll get to all of us as soon as they can , what a GREAT problem to have huh ? First you find out the doors are closing , thing are being shut down ..... Weeks later your up and running a new venture and the phones ringing off the hook ...  | ||
| Spyder12s |
I phoned them on tues and got right through no issues.. said a batch was going out that day.. | ||
| Hdwrenchtx |
had a chance to put a few miles on mine now. runs strong no pop on decel fmf slipon K&N pump gas ecm w 02 on | ||

So is there an option that we can request for O2 sensors on or off? Pros and cons? | ||
| Two_buells |
O2 sensors on, so the ECM can adapt to the individual riding and the engine characteristics | ||
| Duggram |
There was a discussion here in the last couple of weeks about the need for O2 sensors. It came down to how you use your bike. For street it's best to keep the sensors on, for track you don't need them. The O2 sensors can not react fast enough on a race track to be of any value. When you see O2 sensors on the AMA race bikes, they are not the same sensors. I forget the name, but it may be wide band, or something like that. Their purpose is for data gathering to be used later. When I got my Torque Hammer Dris was adament about removing the sensors. My bike stays on the track. Hope that helps. | ||
| Mountainstorm |
EBR told me that if I leave the O2 sensors disconnected the ECM reverts to the base map so as long as the base map works for you all's well. Not sure which sensors report on or are effected by altitude changes or temperature changes but both drastically change the amount of air in each "breath" the Helicon takes, so I chose to run with all of them on. In short: It's optional. | ||
| Fresnobuell |
Cool, so I am now understanding that EBR doesn't turn them on or off at the ECM, it's up to us to leave them connected or disconnect on the bike. Gotcha. | ||

So, if the ecm tells the machine to run at 14.7:1 by default (stock ecm) then what does the race one tell it to run at? 13:1 or some other ratio? Since it's not EPA mandated to run lean and can be set at whatever they choose, theoretically, it could be set for max power almost anywhere, or even to run at 15:1 (or higher) on cruise. Correct? I'm trying to understand why you'd have to disable the O2 sensor on a stock ecm and not on the race if it were mapped the same. I would think that the stock ecm could be forced to run 15% more fuel and not deviate just by changing 2 variables. The first would be the actual percentage change for more fuel and the 2nd would be the base ratio to run at. I'm guessing its a bit more complicated than this though. It would still use the O2 sensors for feedback and attempt to keep it running at the ratio you set, ie; 13:1 instead of 14.7:1 or whatever it is stock. Does this make any sense? It seems kinda obvious that EBR is tuning it for more fuel, simply because of the drop in fuel mileage. I guess I need to get a tuner's handbook for electronic fuel/spark control. I really want to understand it a lot better. I knew what I was doing on older setups just by reading plugs and if I had a 4 gas analyzer available. I don't have the ega machine at my disposal any longer, so my options are a little bit more limited than before. It's been a long time since I've done any serious tuning on a bike.

Mountain, now I'm confused. In my race ECM I have one map. It's the map Dris developed for the Torque Hammer at the time I bought my TH, ~a year ago. Like I said before, Dris was adamant about taking the O2 sensors off. So, because I have my O2 sensors off, which base map does it revert to? How many maps can be in an ECM? | ||
| Chevycummins |
Probably 2 maps, the original programmed map and the ecm corrected map that is calculated using the feedback from the O2 sensors. If no correction is needed then 1 map. That is how I understood it. Although corrections are also done using the Baro sensor feedback, so how many "maps" are there for different elevations? | ||
| Mountainstorm |
Only Buell would know I am thinking. And don't assume that just because my particular "Race Use Only" ECM has the 02 sensors active means that all Race ECMs sold in the past or even today are the same. Be sure to clarify these points when ordering yours from EBR. As far as the whys or wherefores of non-Buell mapping you'd be better served asking the guy that did it. Make sense? My guess is that the guys that figured out how to hack and reprogram the ECMs don't really know everything about them or exactly how to program them fully because they learned what they learned from trial and error (also called reverse engineering if you get it right). This is just my take on it, I am not a tuner, but if you have to cripple the ECM to get the results you want then you probably have a bit more "reverse engineering" to do. | ||
| Chevycummins |
This might be a better way to think of it, 1 map then if needed as determined by feedback from sensors a correction table is applied. It has many calculated correction tables for different ambient temps, barometric pressures, etc. | ||
| Easyrider |
Mountainstorm, If the people who made the maps in the ECM, (Buell started doing this themself from 2008,before external company did it), did what they where paid for we didn't need to do the reprogramming. That sayed, there is NO ECM in the world I know of right now, that is able to keep up with swapping a exhaust. You need to get the fuel right depending on the exhaust caracteristics. |
