    AFV Questions

    A) Changing the AFV will not alter the fuel or timing maps. B) Unless you prevent the ECM from changing AFV, you can reset it to 100 but the ECM will adjust it back to whatever value is needed. And it can happen quickly. For the section highlighted in purple, AFV dropped from 89.7 to 76.8 in...

    2008 XB12R with no oil pressure, black plastic pieces in pump area

    A few days ago, I had started the engine and it was idling for about 30 seconds. Then I heard a crunch sound and then the oil pressure light started to flicker. I turned it off, removed the oil pump cover, and saw a few pieces of black plastic in one of the oil galleys and behind the scavenge...

    Flags 0 to 6 in MLV

    That particular ADX file uses Linux end-of-line markers. Windows and Linux use different markers to indicate new lines (EOL). Windows = CR/LF, Linux = LF. Windows notepad doesn't properly interpret Linux EOL markers, so it just shows the text in one long string. Look for Notepad++; the...

    A different way for you to learn about the various config settings and live data is to look at the Tunerpro RT v5 .xdf and .adx files for Buell: http://tunerpro.net/downloadBinDefs.htm#Buell Just open with a text editor. Within a short time you can become familiar with the file format and...

    osvaldo, much of what you ask is already conveniently documented: http://ecmspy.com/cgi-bin/runtime.cgi Also, if you haven't already, you should look over the Buell Tuning Guide and other info from Gunter Baumann/Nick Pashley.

    MLV question

    Live data stream shows you total fuel length in ms - what is driven to the injectors after all overrides are factored in. Look at the fuel cell for a given load/rpm. The values are uS/58 or uS/50, depending on the firmware level. When the change occurred I don't know (maybe DDFI-3). As an...

    02 Sensor

    The Rapid Bike module most likely utilizes the O2 sensor, so disabling/bypassing the sensor while having the module still connected would probably compound the issue. If the previous owner can't provide any history, best bet is to remove the Rapid Bike module and confirm that the CEL stays off...

    Richer fuel map for a standard XB

    A stock bike with a stock map should not run like this. Best to try and sort out what the cause may be before tuning it, or else you may end up more frustrated chasing a moving target.

    tuning / race map help

    The service manual recommends propane for intake leak detection. But reading what you said about the AFV with the "race" map (I missed that part earlier), then it doesn't add up. Can't hurt to rule that out, though. Unfortunately, "race map" doesn't mean anything useful to me :( One question...

    tuning / race map help

    The ECM is adding ~10-15% fuel in just about all areas that you logged. Even idle, which is closed loop, was quite lean. I wouldn't expect stock vs aftermarket exhaust or air filter to affect the idle fueling that much. If I were in your position, I would check for any intake leaks, and load...

    Oil circulation after swingarm replacement...

    Unless there is blockage, pump priming would have occurred when you cranked the engine with no plugs. Have you checked the oil pressure sensor wire/connector? I believe a grounded sensor wire would cause the light to stay On. I can't recall if an unplugged pressure sensor wire would give a...
