How does this map look? http://silenceisdefeat.org/~greenamp/images/UlyLog gedTuned.jpg This was the result of a datalogged 2007 Race EEPROM *provided to me by Xopti, processed through MegaLogViewer. Rear fuel map was copied to the front and +2 added to the cell values, and front timing map copied to rear as per instructions on BuellitinBoard http://www.buelletinboard.com/forums/showthread.ph p?t=5176 Those of you who have gone through this process, can you give me insight into how my maps compare to yours? (Still working on the square idle btw. ) *Make a donation to Mike if you can. http://xoptiinside.com/downloads (scroll down) (Message edited by greenamp on July 31, 2008) (Message edited by greenamp on July 31, 2008) | ||

Thats a pretty good looking map. How is the idle? If you encounter a stumble just off idle under slow acceleration, consider changes to your timing. I found that ramping up the timing off idle eliminated my stumble. I used a value of 3 in the 20/1000 block and a value of 10 in the 20/1350 block. | ||

What pipe and intake are you running? | ||

Naw, I meant Greenamp's setup. I'm already jealous of yours, TM... | ||

TM, It idles ok but could be smoother. Pretty much just a tad better than a stock idle. I tried your square idle method but couldn't get the idle to stay in only four cells. That was before the tune though, so maybe with mirrored spark maps it will be easier to accomplish. I may try to adjust the rpm/tps axis but that's a bit more intimidating. Chilli, I've got an 06 with a drilled out airbox, with race ecm and race exhaust. | ||

Very interesting. I have a friend who is struggling with his paid-for Direct Link dyno-tuned fuel mapping, who has exactly the same setup. We might just start with your map. Here's a tip, take the cell at 15/1000 and make it 73 front, 71 rear, and see how that works for you. If you are at sea level or so. I have mine set at 68F/66R IIRC, and it is dead-on in the 15/1000 cell and steady (I am at 5280 ft.). Stock ECM, race ECM timing maps, modified race ECM fuel maps, '07 airbox, K&N, home-made pipe. | ||

Hey Greenamp, where did you get the timing maps? Quite a bit different (more advance) than the stock race maps I got from Xopti's website. Also curious how it runs for you, how you like it, issues you may be chasing etc. (Message edited by Red_Chili on July 31, 2008) | ||

The ecm map that I used for datalogging was provided to me by Xopti actually. For some reason I was thinking it was the stock 07 race map. I edited them out of the original picture. Too much Booker's last night I think.  At any rate, I was only able to ride it about 15 miles on the interstate last night before it started pouring. Ran great. The hp/torque curve seems to be a lot smoother. I'll do some more riding here in a bit and letcha know a more detailed report. (Message edited by greenamp on July 31, 2008) | ||

Very cool. I might just have to try your maps myself, as a starting place. These motors do seem to respond to advance well (as long as the base timing is correct, and you don't get carried away!). Mike is a super helpful guy. Gonna hafta donate to his site. | ||

Really love the sound of the Drummer...but my patience is wearing thin for the decel popping and the off idle stumble. Really hope someone creates a solution for the '08 ECM's. Tipsy | ||

Greenamp, Did you set your idle EGO yet? | ||
| Greenamp |
I haven't set it yet on this iteration TM, no. I attempted it before, but the bike was really hard to start when cold. Also had a really hard time keeping the idle within any four fuel cells before, as it would bounce around quite a bit. | ||

Greenamp, If you like, try this: Forget about the square idle for now. Concentrate on one idle cell...lets say 1000 rpm. Adjust your fuel so ego is dead on for that cell, then +2 for the front. Engine must be to temp and cold start enrichment must be at 0%. Don't let the engine get too hot or the cold start enrichment will use a (-) value which will skew the values and cause hot start difficulties. Use fans to keep the engine between the 160-180 range. Once your 1000 rpm cell value is set and ego is stable, then set the 800 rpm cell +5 over and set the 1350 rpm cell value -5 under your 1000 rpm value (front and rear). What this does is when the rpm drops below 1000 fuel is added to bring it back up. When the rpm rises above 1000 fuel is cut to bring the idle back down. As usual, save your maps before you start just in case what works for me doesn't work for you then you can go back. Make sure your tps reset is solid and static timing is straight up. The square idle was a workable solution in the early ecm spy days with the original version. Now that it has evolved and has more precision we have the ability to concentrate on only one cell. Don't forget to do an AFV reset after every change. Good luck, let us know how it works. | ||

Thanks TM, I will definitely try that. |
