Best thing I've done up to this point. Used ecmspy to log and megalog viewer to analyze and create my new fuel map. Logged for about 40 min. trying to hit every cell on the map that I could as many times as I could. Amazed at how far off some of the numbers were. Especially in the high tps midrange area(I have a gp1 jardine pipe). One thing to watch out for is when you load your new fuel map into ecmspy, it will not load cell numbers larger than 255. It will simply keep the original cell number. This is obviously only in the wot area. You just have to manually put in 255(this is as high as you can go). Bike runs incredible. Highly recommended.... | ||

megalog viewer? Like with the megasquirt web site? What all do you need to do this. Also if ur doing a stock ecm can you save it to reload it later like for emissions testing? | ||

Rb, Go to the ECMSPY website and download the tuning guide. It will answer all your questions. Yes you can save the stock map. | ||

Buplaux, whats your method for dealing with the front cyl map? how many logs/remaps have you done? whats your AFV settling at after trying the new maps? thnx! | ||
| Buplaux |
I just made the same map for both. Front cylinder will supposedly get more fuel on its own. What I have heard anyway. Carbed bikes don't have 2 maps so I figured this doesn't either with a common manifold. So far it has not moved past 99.8% so it is working very good. I guess you could make duplicates and then increase the front by a couple percent if ya wanted to. Jeff | ||

Buplaux, what happened to your Xopti tune? I thought that was working well for you? ~SM | ||
| Xl_cheese |
Generally part of the xopti tune requires some custom dataloggin. | ||

You shouldn't use the same map for the front as the rear. | ||
| Mr2shim |
Best thing to do honestly. IMO. If you want to use the rear map for the front. Either, get it dyno'd, and or install a narrowband on the front cyl and data log with it plugged in & the rear unplugged. That'd be the best/cheapest solution I think. what I plan on doing sometime down the road. I'm not using the same maps. I've done several different methods. My personal one seem to work best on my butt dyno. I'll probably see if I can get it dyno'd when I take it to the dealer for the headlight service. Even when I do use the same map on front & rear that were VE analyzed half a dozen times, it runs a lot better than the stock map ever did; no pop, pop on decel, nice idle. AFV stays on 100. Not 112 like the stocker. (Message edited by mr2shim on July 27, 2008) | ||

my method lately has been to log a few rides with ECMSpy, analyze the log with MLV, run it through MLV VE, analyze the cell changes, hand edit the rear map in specific areas in ECMSpy, then apply cell values to the front by using Mesozoic's Excel sheet. i did a variation of the 'square idle' before the work above, bike is running great, got my AFV settled at 100 giving the LCL area a ~5% increase based on my previous map that had my AFV at 105% consistently. last tweak to my current map will be to analyze the WOT area, needs about 5% more in the upper rev range. when the AFV was adding 5% across the whole map the cruise was a little rough but the WOT area was sweet, wheel would loft switching gears when up around ~5-6K. i tried to keep as much of the stock race map in tact, only tweaking where i saw a need for more or less fuel. every time i've tried equal maps, equal timing, etc. my 12 doesn't like it. might get great idle but poor on-road performance. EDIT: i forgot to add that i did some work on the decel region as well, got rid of pretty much all pop, that area was really lean previously. bike sounded badass yesterday gurgling with a mellow pop or two on decel rather than POP, POP, pop...

Either, get it dyno'd, and or install a narrowband on the front cyl and data log with it plugged in & the rear unplugged. This is what I'm going to do, seems like a reasonable solution and should give fairly good results. I'm guessing it can be done for under $100 using ECMspy and MLV. The only thing better would be dual widebands and dyno time, but there goes a good chunk of your paycheck. | ||

See the sweet welding post for an o2 on the front. I did a bunch of datalogging this weekend on each cylinder. Did 3-4 runs then swapped cylinders. Repeated that about 3 times. I'm datalogged out.  I worked on getting the front and rear to settle on an afv of 100. I'm pretty close. My AFV seems to drop a bit when I do a high rev decel. I'm going to ride it normal this week and keep and eye on things. I also tuned the idle almost to perfection. I did a variant of the square idle and dialed eacy cylinder in until the Ego Corr. hovered between 100 and 105. On the idle I took the average of the 15/800 and 15/1000. Then an average of 10/800 and 10/1000. Next I bumped them up until the ego corr was where it needed to be. | ||
| Ferocity02 |
Are you data logging in open or closed loop only? Or are you just doing it like normal? | ||
| Xl_cheese |
I locked the AFV in at 100 while dataloggin as well as disabling the open loop learn enable. Logged in open and closed loop | ||

So what does all this hours and hours of logging, adjusting, etc,etc,etc, ac tually accomplish? How much more HP, or torque, or mileage , or whatever, is being developed with this ecmspy???? I do not understand=== I got rid of my '07 Aprilia Tuono, and bought another xb12scg, to try and keep things simple...seems some folks would rather complicate things. PLease enlighten me.... | ||
| Swordsman |
Packrat, from what I've garnered, XB fuel injection is pretty rough around the edges. Mine, as well as many others, do not cruise well. They may run like a bat-outta-hell just fine, but day-to-day riding needs refinement. It's my personal opinion (no proof whatsoever to back it up) that the stock maps are tuned more for dodging a catalytic converter than for smoothness. I can't think of any other reason why the engineers couldn't come up with better, smoother maps, when it's obviously possible to do so. ~SM (Message edited by Swordsman on July 28, 2008) | ||

I think the same thing, swordsman. Trying to achieve the best MPG & dodge the catalytic. | ||
| Typeone |
+1 to Swordsman's comment. better idle, smoother fuel delivery, no surging during cruise, little to no ping, no popping on decel, more power on tap and still getting the same ~47MPG. i'm not after peak numbers, just a better overall experience on my XB. tried the TFi, Race ECM, VDSTS and just wasnt fully satisfied. | ||
