I'm wanting to get some information on which ECM I should go with or if I should go with ECM spy. I've got a jardine exhaust I'd like to run. I've heard some things about the ebr ECM that they raise idle rpms and reduce engine braking. Both of these parameters I'd like to leave the same. Id just like some extra HP and TQ. What about the jardine tuner that's on eBay? Has anybody used that yet? ECM spy. How does it work? Will it void a warranty? Can you program it back to stock? What does the whole ECM spy cost? Cable and software? | ||

Do you know how to tune an engine? If yes, do you have the right equipment to do it correctly? Just guessing here, but I'd bet not since most guys don't have access to a shop. You need either a 4 (or 5) gas analyzer or wideband O2 sensors to do it right. Neither option is cheap, although wideband isn't too bad. Mine was about $550-600 for the pair with controllers and a display. After that, you need to spend a lot of time actually tuning it. How many hours depends on your equipment and how good _you_ are at doing it. I know for sure that Erik Buell Racing spent numerous hours on the dyno to just do ONE pipe and they know what they're doing. Raised idle really isn't that big of a deal, you're looking at maybe 100-200 rpm. Reduced engine braking is part of the package as well, learn to use your brakes more effectively, not rely on the engine to diesel and slow you down. The jardine unit is just a piggyback patch, I don't think it works all that well. It certainly doesn't compare to the results you'd get from Erik Buell Racing's ecm. ECMspy, it's software. It allows you to mess with EPA mandated fueling & timing. There's a manual available on their site I think that explains most of it. Have fun reading it, it's a lot of info. Warranty, dunno, just depends on what you do to it and if it gets damaged in the process. Yes, it can revert back to stock, assuming you don't brick the ecm somewhere along the line. Same as loading a race map into it. Get one bit of data wrong, you might end up with a bricked ecm. The cable can be had for $40 or so off of ebay. No idea on the software cost, although tunerpro is free and does pretty much the same thing. No instructions though. Good luck either way, although I'd recommend going to Erik Buell Racing. They've already done all the leg work for you, so it's cheaper in the long run. I guess the real question to ask is, what's your time worth? Mine usually goes at about $60-70/hr at a minimum. Figure it would take me longer to tune than they did, maybe 6 hours on a dyno. At that rate, plus the cost of the dyno, hardware and whatnot, I'd be well over $1500 by the time it was all done. | ||

The free version of ECMspy does not work on the 1125, the paid version does. Any type of modification to your motorcycle can affect your ability to have work covered under warranty.
Yes if you make backups.
A cable will run you around $50, they are for sale on American Sport Bike and Ebay among other places. ECMspy itself requires you make a donation, I do not know the details, you will have to go to ECMspy.com for that. An alternative is to use TunerPro, it is free and compatible with all Buells.
Skip it, there are better solutions out there.
They lower the idle, change the IAC settings, change fuel maps, fan operation, cluster COLD display, and many other things. It is well worth the cost, and it is a lot easier than messing around with the stock ECM and potentially causing your bike not to run. | ||

I used a program similar to the ECMSpy on my 1125. Very happy with the outcome. BUT...as Dean says, you NEED to fully understand the tuning of an engine. The why's AND the werefores...so to speak. I did mine by the butt dyno method. It took a long time to get it even close to right. But the final outcome...the engine runs cool, the milage is reasonable, the power is great....and...I still have engine braking (it's "not" dieseling...!). I'd probably agree that the Buell ECM is the easiest way to go, but they need ALL of your parameters (info) for them to be even sorta close. One does not fit all...! Have fun. Mike | ||

I suppose dieseling isn't the correct term, but I equate the engine braking to a jake brake on an 18 wheeler, so I guess thats why that stuck in my head. | ||

I have the Jardine Pro-Tune 3 that I'm not using (I now run the Erik Buell Racing ecm). It works well enough. I'd sell mine for $200 shipped (I paid over $300, but they now go a little cheaper). Let me know if you decide to go that way. I'd also be happy to answer any questions you have about it. | ||

yeah i can def recommend an existing solution. unless you are an expert tuner. otherwise EEBBBRRR has out of the box tunes for several exhausts. although i don't believe they do custom work ont he ecm's anymore from what i've read here as delivered solutions pretty much rock. i recently found out the hard way about the ecmspy issue, thanks froggy for the assist. in the end i had to go to the dealer to unfix what i 'fixed' as a result of a 'theft error' being set while i was fooling around with mine a few weeks ago.... | ||

On engine braking - IMHO it's not about braking. That's what the brakes are for. It's about downshifting at speed. It's critical that you don't upset the bike and affect rear tire traction under hard braking and turn entry. That's why there are slipper clutches. Reducing "engine braking" makes it much easier to downshift smoothly at speed during braking and turn entry, so you can be in the correct gear for turn exit. | ||

Hopefully not too much of a hijack... I'm looking to get the E.B.R. ECM when i pick my pipe. I know they sell the software to adjust the ECM as well. How easy is it do use - anyone have the E.B.R. software for their ECM? If i start w/ the map they provide from E.B.R. and then just adjust i figure i'm starting at a good spot and a few dyno's later should be pretty dialed in. BUT i'm not sure what the interface is like or how easy to do it. Thanks!! rob |
