    One more time on ECM

    Yes you are correct. Once AFR deviates much from 14.7 the narrow band sensor won’t read very accurately. Hence the use of wide band.

    Does the earlier bikes have a spare analog too? Say 2004?

    One more time on ECM

    Yes thats how I understand them to work too. On mine looks like O2 target voltage is set to 0.493V and can be adjusted. Not 100% sure what you mean by "signal is too easily running away abruptly from 0.45 V ". Up and down AFR could be a symptom of fluctuating idle, however I doubt narrow band...

    One more time on ECM

    If I understood osvaldo correctly, he would like to data log with all the original settings and sensors in place/functional, plus add wide band too.

    One more time on ECM

    One slight correction, those numbers are injector pulse widths. Each point equals to 58 microseconds. Say table calls for 56 points then injector will be open for 3248 microseconds or 3.248 milliseconds.

    One more time on ECM

    Thats an excellent question and I was wondering that my self. Maybe some one with 2009 can chime in and tell us if there is an unused analog input.

    One more time on ECM

    Osvaldo welcome to the forum. I love Italy, very beautiful place. Excellent food, wine and very warm people. First question. Computer extrapolates data in between the cells. Just depends on exact rpm and load. ECM is used to calculate through math equation interpolated value. Not 100% sure...

    Any last ideas before I dive into the world of custom tunes?

    That was me. Your timing map in idle region doesn't look all that different from mine.

    Any last ideas before I dive into the world of custom tunes?

    I dont think thats it man, here are few shots of TPD below 80-85 degrees and no enrichment. This is a good one, RPM go from ~2658 to ~4972 and acceleration enrichment cuts out at 3136 RPM. Wonder whats going on here?TPD around 71 to ~65.

    Any last ideas before I dive into the world of custom tunes?

    Did a log on a ride home from work. I think I might have found a reason for crappy low throttle jerking in my bike. It looks like deceleration fuel cut off kicks in if load is less then 19 and speed below certain rmp. Here is a screen grab of deceleration region and percentage of fuel cut. (If...

    Any last ideas before I dive into the world of custom tunes?

    edit the third LOL, with some better data. (I hope you take this as me being curios and not trying to challenge or undermine anyone) I'm simply talking about acceleration correction and how I think it applies here. lowkey perhaps you can explain those screen grabs with engine accelerating and...

    Any last ideas before I dive into the world of custom tunes?

    Acceleration enrichment only last one revolution of the engine, once the average throttle position is equal to current throttle position acceleration enrichment is zero, but the engine can still be speeding up/revving up even thought accel enrichment is zero. If you agree with that then I miss...

    Any last ideas before I dive into the world of custom tunes?

    lowkey, the reason AFR is at 11.38 instead of 13.0 is because the cell in which you want 13.0 is at steady state throttle application. If you held throttle at 175 and RPM at 2350 for throttle position to average 175 then your afr will be at 13.0. However, in the screen grab above, looks like...

    ZTL2 worth it over ZTL1 ?

    Great answer Niklos, thanks.

    ZTL2 worth it over ZTL1 ?

    If you had to redo, would you stick with the same set up or try a different master cylinder instead? Something like Brembo RCS15 to improve the feel and control?

    Any last ideas before I dive into the world of custom tunes?

    I think you guys confusing acceleration enrichment and how it works. Its not acceleration of the bike but rather the difference between average throttle position and current position. Its only active when throttle is outside the TPS average. I had to reread the tuning guide (5.1.4 Acceleration...

    I haven't had a chance to look through your logs yugo. I did see them up on the google drive.

    Do you care to post a screen grab of your timing table? Curious to see how it looks.

    No problem. I found I have better luck uploading to image hosting site first before posting on a board.
