I need some tweeks for sure I have roll on pinging.
I need to do some data collection and see if I can figure this out I am going to end calling fuel moto before to long.
First, I noticed that the gear ratios differ between the FM and the stock tunes. 1st and 2nd are the same in both. 3rd and 4th are both .00098 smaller numerically on the stock tune, and 5th and 6th are .00294 and .00297 smaller, respectively, on the stock tune. If the gear ratio is actually a reflection of the mechanical gear ratios of the motorcycle (an assumption, on my part), then they shoud be the same, right? The fact that they're not makes me wonder if perhaps the values in the FM tune apply to a different year, or different engine family (my bike is a 2011 Dyna SG). The differences are small, to be sure, but there's no point in me correcting the speedo calibration values later if these numbers are wrong to begin with. Obviously, my question is, should these numbers match?
Second, I notice that my stock tune has a value of 1 in the active compression release parameter. I DO have a 103 SE big bore kit, but that kit doesn't include a compression release. The FM tune has a value of 0 for this parameter, which I feel is correct. So, I'm assuming that the dealer download that I got when I bought my bike (with the big bore kit and cams installed) is in error. I guess I just wanted to confirm that there wasn't any other reason for this parameter to be toggled on...
Thanks in advance

Wow!!!! I mentioned auto timing a few months ago as a cool feature. Glad to see it finally...watching now very closely...Thanks...
I have my speedometer set with the GPS, which I assume is correct, and VSS shows 2-3% slower than the speedometer. This is a problem because the way DJ is programming the MPG-gauge accuracy in the latest beta FW is to use a new parameter called "MPG calibration." This adjusts not MPG directly as it suggests but rather the fuel-used parameter. The beta-FW now has this new calibration available from the PV only (i.e. not WinPV), and when you tweak this and the Speedometer Calibration you will have a correct MPG reading.
The problem is that on my bike if I adjust Speedometer Calibration for MPG the speedometer will not be correct. VSS (changeable with Speedometer Calibration) is 2-3% slower than my bike's speedometer and both are changed with the Speedometer Calibration.
Y'all please check yours and let me know, as I'm trying to convince DJ that doing it this way is a bad idea. If everyone's bike is like mine you will have to choose two out of three gauges to be accurate, as you can't have all three.
The Power Vision Log Tuner application allows users to fine tune their calibration with or without a dyno. It utilizes the Power Vision unit as a powerful data logging device along with an easy to use software application to create your tune. The PV Log Tuner software uses your logs and PV value files to create corrected VE and Spark tables based on O2 sensor and knock retard events. The Power Vision log tuner software is free and incorporates two powerful tuning platforms:
Power Vision Log Tuner Basic - uses the factory O2 sensors
Power Vision Log Tuner Pro - uses the Dynojet Dual channel Auto Tune module with Bosch Wideband sensors
We will be putting together a video tutorial as well as some additional tips and pointers for using this excellent tuning tool next week. We have been using the Basic and Pro applications extensively and can assist users with any questions that come up along the way.
You can download the Power Vision Log tuner software and user guide from our website at www.fuelmotousa.com/powervision.htm

I can not seem to save the Power Vision Log Tuner user guide. Not to worried at the moment. I am pretty excited about this.
