I'm currently running an HMF exhaust with a K&N drop in (on a 09 1125CR) and now I'm looking to match the computer with the set up. I'm in Phoenix so running temps are high and elevation is about 1500 ft. kinda looking for which route might be better for my bike. | ||

Welcome to the site. I think you will find the overwhelming majority here pointing you towards the Erik Buell Racing ECM. Since they can specifically tune for your pipe I say go with them. | ||
| Roughian98tj |
yes, but Power commander has a map on their site for the HMF pipe and K&N as does Erik Buell Racing. | ||
| Mikellyjo |
Good point...but can you get it for 250 bucks? And when you decide to change pipes can you get it updated for 35 bucks? Granted it doesn't have the same "bling" power commander, but it is a race ecm from the man who designed the machine in the first place. | ||
| Roughian98tj |
well I'm not trying to make a case for either one, just throwing what I've found out there so I can get opinions. | ||
| Firemanjim |
Interested seeing one of the PC's on an 1125,given the ease of tuning them on other bikes. Too bad you are not closer--we can get deals on the PC's and would cut a good deal on tuning it to see one. | ||

Erik Buell Racing ECM all the way. The power commander only alters fueling and isn't even a dual wideband. The Erik Buell Racing ECM has a different timing map among other changes. Having had a Motty dual wideband afr tuner and now the Erik Buell Racing ECM I prefer, significantly, the Erik Buell Racing ECM. | ||

WHAT TYPE OF RIDING YOU DOING? | ||
| Bueller4ever |
You'll want a dyno tune with power commander. If you don't intend to do that, then get the race ecm. PCV won't cause charging issues, apparently race ecm will. Power commanders maps are always to rich. | ||
| Trbulnt |
I have zero charging issues with my Erik Buell Racing ECM! I will say it again...this ECM completely changed the way the bike runs. It is a much smoother running machine now. | ||
| Bueller4ever |
Charging issues is not really a correct statement. Battery draining issues due to fans running more often would be a more correct statement. It may not be a problem for you, just like the wiring harness isn't a problem for me (no long idling or constant stop/start), but others have reported a problem. | ||
| Roughian98tj |
ok Erik got some more of my money today, hope its worth it. | ||

I'm running as PCV I tune bikes with them all the time. And yes you can alter more than just fuel you can alter spark too. PCV is a great tuner. Even better if you have access to a dyno. PCV is tried and true. I am in no way putting the Erik Buell Racing ecm down I love ERB! But in my case I have been running a PCV with no problems. | ||
| Avalaugh |
Dsmitty25, what numbers are you getting from the PCv ? | ||
| Mrbuell |
I am using the PCV with dual o2 sensors and it works great | ||
| Ratsmc |
Dsmitty, I have never seen or heard anywhere that the PVC can adjust spark. In fact, everyone I have ever spoken with has said it doesn't. I also can't find anything on their site about it adjusting spark. | ||
| Firemanjim |
All PC3 and PC 5 have timing table adjust as well. | ||
| Ratsmc |
Okay, with a little more searching, I have been able to track down that they do offer spark adjustment "in some cases". Can anyone confirm that the 1125 is one of those cases? | ||
| Mikellyjo |
I guess I just don't get it (no surprise here). I understand that before the Erik Buell Racing ECM was available (before the fall) that a plug and play fuel management system was a viable option as long as it was accompanied by a dyno tune to make it right. However, now that Erik Buell Racing is offering an ECM tuned for specific exhausts what is the advantage? Outside of changing exhausts and being able to adapt to that, but Erik Buell Racing will re-flash your ecm cheaper than a dyno run for sure. | ||
| Raceautobody |
It would be interesting to see if anyone had success with the Auto Tune function for the PC5. Al | ||

However, now that Erik Buell Racing is offering an ECM tuned for specific exhausts what is the advantage? One advantage would be that you could make other modifications and get YOUR bike tuned for YOUR mods, especially with Auto-Tune (if it works, as has been asked). For example, I would like to add Dris' 1125 aftermarket velocity stacks but there is currently no tune for that with any exhaust combination from E_B_R. Yes, it is certainly more expensive if you have to get a dyno-tuning session for each change with a PC V (assuming the Auto-Tune isn't supported), but you are guaranteed a tune specific for you. Do you believe that all motors are exactly the same in performance and specification, even if put together with the same parts on an assembly line? | ||

If you are going through the expense of dyno tuning then skip the pcv and get a cable/tunerpro. Save the pcv money for the dyno session. | ||
| Bueller4ever |
PCV is much simpler to use than tunepro. Unless you have your own dyno or really know what you are doing, then tunepro isn't a viable option. pcv offers no timing adjustment with the 1125, this I know. | ||
| Xoptimizedrsx |
no way the Tunerpro is more simple if you use it correctly. It has a data log section which tells you what the exact fuel values need to be based from all sensors on the bike Not just the O2 sensors. No dyno needed. you guys need to get out of the dyno world. its not accurate for real world use on the street. take any map on the bike made on the dyno and adjust to you riding it in the real world on real roads and the map from the data logs will be different. plus you will see in the AFR gauges that the dyno map may be great on the dyno but when put on the road its varies a lot. some never learn.... lol the dyno cannot adjust for weight wind and payload like real world logging does. a dyno cant adjust for up hill and down hill. we have many things a dyno cant do. If dyno's were the key to perfect maps why does so many race teams (all engine types) use the data from logs to see exactly whats going on and adjust to that from the real world use and not the dyno? Dynos may get you in the correct field but not in the game as exact fuel needed. | ||
| Bueller4ever |
You can't use data from the stock 02's, in the stock header location, for WOT tuning. If you could, then the bike wouldn't run in open loop under those conditions. Even wideband sensors may not work well in the stock location. Do you tune your 1125 using tunepro? Do you own a 1125? Have you tuned a bike on the dyno using a power commander? | ||
| Mrbuell |
My auto tune with dual o2 is working great so far. Both cylinders are mapped differently. | ||
| Xoptimizedrsx |
yep had a dyno for a few years. Yep have done 1125's on the dyno. yep before you guess. look at whom did the tunerpro stuff before questioning what data I have and ect. someone may have more data than you expect. in order to link to the bike with tunerpro you need the adx files... who do you get them from? that is me or someone who got it from me. did you know that? I have the full tuning system from multiple places. PMC tuner (ebr tuning) ecmspy mono full version Tunerpro with all files and files not posted to the public for security reasons in the ecm data. he question is apparent you dont know how to use Tunerpro correctly yourself. did you get the adx. I wrote those lol. did you get the correct xdf. I started them but Ecmspy passed me up when they saw it was working so I stopped working on my versions in xml format to make into the xdf needed in Tunerpro. Ecmspy did the current xdf's and currently have them for public download . I own 2X 1125 ecms and can run them on the bench as a simulated bike. can you do that? you are correct stock locations are not best for wideband or NB but keep digging you will see how and why O2 alone is not the real way to tune. Thats putting all your apples in one barrel. Not a good practice. I have the daul widebands as well with XD16 gauges to see live data on the road in compared to what it was on the dyno. Mounted with bungs in correct locations. I even have egt readings. you are wrong on NB for wot as well you can use the data if you know what the values are. which should be .76 for a good base. but where do people get there info I dont know. memorize the scale for NB0.00 conversions to afr and your good. its not thwe sensor that sets the afr its the adjustment of the ecm. that does the settings based on the report data the O2 does. NB reads fine for general usage. Bewaree of internet training they are all stuck on Nb rabge as locked to 14.7 the sensor is not locked ts measurement device that uses .01 to 1.0 voltage. again the ecm applies the data and tells the afv what to do with it not the sensor. fyi you can reprogram the ecu (ecm) to use widebands directly br rescaling that data area and adjusting the tables to match. then feed your wb directly to the ecm. you can also dasy chain the data and do it on ecm's with only one data line and give it front and rear data. newer ecms have two lines with two sensors. scale both to fit the WB data needs. end answers' yes I have ecu's every type ,yes I have data more than You know. I even have the entire ecm dfi1,2,3 on access based database formats for every byte applied to the eeprom chip outside of what is show in and burning with the programs. we just chose to only do certain sections in the final release to the public. Mrbuell glad you like the V cause i have not tried that version. since I use the ecu's directly when needed. | ||

OWNED!  | ||
| Bueller4ever |
So you don't own the bike in question, got it. | ||

Installed ebb ECM today... Noticea nigh difference right away al low rpm. I can actually drive in stop and go traffic comfortably now. It does seem much cooler also... Worth the money just for those 2 things. I did see my battery light come on for the first time, I had started and stopped the bike lie,3 times so it could be that. Went away after the ride. If you want a surethimgget the ebr, if you plan to playground with the setting get the pc or full ebb kit. |
