So I got back into Buell about 2 months ago due to the inability to shake the memory of my 99M2 that I sold (like a fool) from my mind. I picked up a stock 02 S3T with 6500ish miles (now 8100 or so). I hemmed & hawed about leaving it stock & predictably ended up with a Supertrapp & American Sport Bike race intake. I messed around with EcmSpy a bit & managed to load the race map in & figured it would be fairly well tuned. It felt fair but like a slingshot with not too much power until upwards of 4000 RPM. Back in 2000 or so, I rode a friends race kitted X1(intake, headers, exhaust, ecm) & I remember the slingshot feeling & that my M2 was a much better ride. Needless to say, I wanted a bit more out of my S3. After reading about the tuning process on here & different sites, I decided to do some datalogging (which took a while to get figured out due to Windows 7/EcmSpy conflicts) & make myself some custom fuel maps. Over the past 3 days, I've done some work & have a completely dialed in bike. This is the bike I wanted! It pulls quite well from just below 3 grand straight through to redline (which will be reached quite infrequently). It is hard to believe just how much different the bike feels over stock or modified with race ecm maps. I just wanted to share my experience as someone who was a bit hesitant about FI vs carb. As of today, this thing is running exactly the way I want it to -seemless power, efficient & smooth. And the best part is, I tuned it myself despite my relative lack of computer skills. To anyone out there thinking of converting from FI to a carb -don't. Give the FI a chance, you will not be disappointed! Kris | ||

Kris, Hey Cool. Awesome to see solid use of the tools for FI. I not new to FI, but to ECMSpy. I program in C and have tons of system setup experience (Unix/linux/mac) but not so much windows. Would you elaborate on the win7/Ecmspy issue? Also would you describe you data logging setup? I'm looking to do the same for my 2001 X1 (Stage 2 heads, Whites brothers pipe, Race intake). I have the Race ECM but always wanted to take a better look at the map. Thanks matt | ||

Hey Matt -The issue had something to do with where EcmSpy was installed by default. It was in C:/blah.blah.x86 It seemed to work fine until I wanted to record logs. EcmSpy would record them but I could not access them for analysis in the "Megalog" folder under x86/ecmspy for some reason. I found someone on another message board who had the same problem & he told me to install the program to my desktop & all has been well since. Here is a brief description of the process. Essentially, all you need to do is hook your laptop up to the bike, get the program started up, hit the floppy disk button to start recording and go for a ride. I was told to use the entire rpm range as much as possible for that first session so the maps could be adjusted throughout the entire throttle position/rpm range. Next, you have to use Megalogviewer to analyze the data. I'm not sure exactly what it uses but I *think* primarily it looks at exhaust gas oxygen content to determine the correct injector pulse width to achieve a 14.7 to 1 air fuel ratio across the entire fuel map. From there, you record your new map for the rear cylinder, load it into EcmSpy at which point you copy & paste to the front cylinder map, add 2 or 3 to each cell & burn to the ecm & save the maps. MY description might sound funky but once you do it a couple of times, the workflow makes sense. There are a couple places for error if you're not careful but it's well worth the effort & won't be a problem if you pay attention to what you're doing. I'm sending you a few links via PM. For some reason, I can't seem to find my PM's on here but you can email me at kn_wyman at hotmail dot com if you have questions or would like to continue the conversation off board. LaFayette: Thanks for the compliment! I've read many of your posts & find you to be an excellent attribute to Badweb & the Buell community. Thanks for the informative posts -keep 'em coming! I'm interested in your timing plug crankcase ventilation setup, by the way. Can you explain a bit more about what you did? Kris |
