First off I searched about the spy but it just soon much info so maybe somebody will have link to a good thread or maybe just answer a few questions. I don't have it on my bike yet but would like to get cracking once my pipe gets here. I have lots of Dyno time with power commanders and rate tuners but non for the spy. But I want to know if i can. Turn off the o2 map the bike and then just leave it unplugged so the bike won't change my map. If a fuel table cell says 100 for example what does the 100 stand for? Like if i add 10 to how will it effect the a/f if its lets just say 14.0? Does it also work on tubers? The version my buddy has was the free down load from a few years back. I'll be tuning a 03 and possible 05 and a 01 x1. Thanks. Lemme any information would be a help. | ||

Maybe this thread will help you out. http://www.buellxb.com/Buell-XB-Forum/Do-It-Yourse lf-Buell-Mods/ECMspy-megalog-tunning Instead of disabling the O2, you can lock the AFV at 100 and the ECM will not make changes to the maps. You will need to lock the afv at 100 when you do your logging anyhow. The numbers in the fuel cell are basically the amount of time for the injector pulse. Adding fuel to a cell would lower the a/f ratio. Yes ECMSpy works on the X1 ECM's. | ||

Once you have the tuning set, why wouldn't you want the ECM to adjust the AFV for different conditions? If you are trying to set a richer than 14.7 then it seems like it would be best to get a wide band o2 and controller that can be programmed so that a reading of say 12 sends the 14.7 signal to the ECM. That way the AFV could still change for different conditions and you would still have your rich performance mixture. | ||

Just tune the learned fuel areas to 14.7 and tune the rest to what you want with 02 sensor left on.That is what we do. | ||

Thanks for the info...haven't been in here much been out riding the whit outa the buell 1,000 miles in a week, not bad. Firemanjim have you ever ever turned off the o2s and mapped the bike or do you always leave them on? I do mostly power commanders at work some super tuners if the customer already has it. We disable the o2s when tuning the bikes and then we just leave them off once we finish the map. I just want to get the best result possible. its not like I have to pay to tune it so I dont care if it takes all day. | ||

So I just finished the first datalog session and created the new map... It's still pretty "spikey" in some areas so that brings up a question... Should I manually smooth the curves or just let the datalogging try to do the work for me? Probably going out after dinner to do another ride and see what it looks like. Before starting I already had an AFV of 105 so before the first logging I multiplied all the cells in both maps by 10% to make sure it would be safe, then locked min and max AFV at 100 so megalog wouldn't need to chase it. Megalog did remove fuel in several areas and added in several others which is what I expected. And if you don't have to pay for dyno time, can I come over? It's hard to try and hit all the points when you are worried about getting a ticket for speeding, so far I've had to stick to full rpm runs in second gear and I know I really should be doing them in 3rd or 4th gear.

Yeah free Dyno time haha. I work at a shop ( www.Dyno-Power.com) so i can tune my heart out. I didn't plan to use the data log but just make runs at every listed throttle position then tune the rpm cells. Ill use win pep to do that. | ||

Well my first map wouldn't idle when cold, blasted the pre-tune map back in and went for a ride and made another log. Manually adjusted an idle cell that I though was much too low and it was OK, went for another ride and log. Idle area stayed pretty close to my manual adjustment so it must have been closer, need to wait until tomorrow to see how it acts when the motor is cold. | ||

OK, here is the first tune that seems to have worked, front cylinder is 3 higher than rear so I only show front to make it easier   And here is the tune created using the above as a base map and doing more logging   I still have an off idle hesitation that I'd like to fix, any suggestions? I can zip the logs and maps if that helps. | ||

Mike, we always leave the 02 on unless it is a racebike with alot of work when we dyno. Just need a dyno with brake so you can run learned fuel areas. Hold at 2400 at 16%,20%, 24% throttle etc. Need to hold at each cell and see if AFV skews from 100,if it does you tune that cell to 14.7 until it holds. All other areas you can tune as you wish except idle is closed loop as well. |
