http://www.erikbuellracing.com/store/parts-accesso ries/fuel-injection/cmi-lite-diagnostic-tool.html Anyone use this and have any thoughts on them... Got a 2009 xb12 and still having problems, No check engine lights at all Still not Right.... This is the other Tread going on this ( http://www.badweatherbikers.com/buell/messages/32777/741911.html?1404653414 ) ,Just wanted to see IF any had bought this tool and used it for resetting the Air / Fuel ratio back to stock...for 2009 as I have no other means to do so at this time....

I saw it a while back. It is made by IDS (the DDFI-3 guys). I thought it was a neat idea and actually similar to one I had been working on. However, I do see it as special-purpose tool, for convenience. A good Data Link (diags) cable allows you to do everything the CMI Lite does and more. If you want a quicker way to do only those few but common service items and can justify the cost, I'm sure it does that well. | ||

I recall Ratbuell posted something about his experiences using this. Don't remember the details. Hopefully he'll chime in, 1313 | ||

Thanks I just messaged him....If he would comment on this link.. | ||

I've used it but you can reset an 09 without a tool. Mines an 06 and I need the tool...and it works great. Read your owners manual, the reset procedure is in there. | ||

ratbuell for the TPS reset yes..But not the Air / fuel ratios ??? | ||
| Hogs |
I know the 2009 can reset the TPS no programs needed..But to reset the Air / Fuel ratio back to stock or to the 100 percent VAlue whatever that is I believe I need a program for that, just like you would need for a 2006 ...Unless you know different ?? Or are you saying in the Sevice manual as well there is a way to reset the A/Fuel values without any programs at all? Thanks (Message edited by hogs on July 07, 2014) | ||

The AFV cannot be reset without a program (Tunerpro, ECMSpy) or specialty tool like CMI Lite. Tunerpro allows you to reset the AFV and also change any other parameter, for free (donation suggested). You are probably aware of this already, but the AFV can and will change multiple times as you ride, especially when you have deviated from a stock configuration. It doesn't take x number of miles or 20+ minutes, as some believe. The ECM can adjust the AFV in as little as 21 counts of difference between EGO correction (from the O2 sensor) and the current AFV, which can happen in seconds. With some time buffer, your AFV can change every ~60 seconds, if needed! Lets say you set AFV to 100% and go for a ride. If the ECM sees that the EGO correction has consistently been 95% while you are driving in the closed loop learn ("calibration") area, it will immediately change AFV to 95%, undoing the AFV reset you just made! Hope that helps with your decision! | ||

Readyxb - Unless you set the AFV "range" very small. That way, it won't vary a whole lot, or you can widen the range, so it will vary as much as you like. At least on the older (ecmSPY) versions. Mike | ||

95% was an example and is also the default "decrease" factor. The point I was trying to share is that AFV will do its job and change when needed, despite being reset to 100%! Trying to help the OP make an educated purchase. | ||

Thanks Readyxb I just made a educated purchase from you Thanks (Message edited by Dick on July 25, 2014) | ||

Thank YOU! I really appreciate it! | ||

OK, have not seen where in Tunerpro you can reset AFV, clue me in. And have noticed in the last year all the Buells I have had on dyno--- if you shut off bike with kill switch and count to five and turn it on--- watching with ECM-Spy, the AFV will reset to 100! I was doing this to give the bikes a chance to cool down a bit while I was making tuning changes and saw this happening ,so started to try it on all the bikes. | ||

The CMI lite tool is a quick way to check idle parameters, reset TPS, clear and "view" trouble codes, and reset AFV to base specifications. The "readout" is a series of blinking led's. While it is an effective and PORTABLE way to perform limited functions, I prefer to view what's happening via an analog or bar graph system whenever I am checking for any "serious" potential difficulties. That being said, the $140.00 for a "quick" and portable system is worth the money so long as you realize the limitations. (my .02 cents) | ||

>>OK, have not seen where in Tunerpro you can reset AFV, clue me in. >> It is under Scalars -> AFV Rear in the Parameter Tree. There is also "AFV Front" for the 1125 models, but not all XDFs have that scalar added (you can just add it yourself). Download Bin From Emulator to Tunerpro -> modify AFV -> Upload Current Bin to Emulator >> And have noticed in the last year all the Buells I have had on dyno--- if you shut off bike with kill switch and count to five and turn it on--- watching with ECM-Spy, the AFV will reset to 100! >> I have only seen this once on my 2008 XB. I had just recorded a datalog session and, before turning the bike off, I viewed the AFV live data parameter (it was 97 if I recall). I shut the bike off, downloaded the EEPROM, and saw that AFV was 100! It's a slightly different scenario than yours, but the results were the same. This of course puzzled me, but I came up with a theory: - There are two "AFV" storage values: one that lives in the EEPROM, and one reported/used during runtime. - There is a minimum time delay that must elapse, 60 seconds, before the ECM can update AFV in the EEPROM (possibly due to limited write cycles of the part used) - The runtime AFV, however, can be updated on the fly by the ECM as needed - only around 21 O2 cross counts supposedly needed where EGO Corr. differs from AFV. FYI, I have seen AFV change in much less voltage transitions after entering CLL, but that is only what the ECM reported; the actual cross counts could have been higher due to datalog sample rates. | ||

So the theory is: the last AFV written to the EEPROM was 100, and the "current" runtime AFV was different than 100 but had not yet been written to the EEPROM when the bike was turned off. Correlation with a complete datalog should help confirm or bust this theory! | ||
