Sorry 0 I just saw the posting about the update client page not allowing anyone to fdownload the firmware - still anyone have it on file before it went down?
I have a 2012 dyna switchback 103 with power vision tuner . I have a Stage one air filter (K&N HD-0808 High Performance Replacement Air Filter) . I am running a D&D fat cat 2 into 1 with louvered baffle . Fuel moto gave me a great tune to start with and after several autotunes and different map configurations , I still like theirs the best . Anyone have a finished map close to this setup, I would like to give it a try in my bike .. Thanks , mark
Here are two questions for you guys. Why does a good tune all of the sudden go bad, as far as no spark knock then a lot? Secondly, Why am I hearing pinging, and my power vision showed none?
Thank you for any reply to this
Bad fuel can certainly cause pinging without any other engine/map changes..... Try a fresh tank of 93 octane gas from a brand name gas station that has high volume traffic. See if that get's your engine running normal with the current map.
I enabled closed loop and leaned out my cruising area just to see if my temps would stay low and if my mpgs would improve without a drop in power.
It worked! I'm getting 39mpg, temps are the same, and my butt dyno hasn't noticed a drop in power when I hit the throttle at 75mph.
Back in the fray.
I keep a "ECO" map and an Open loop map (Performance/cool) map on the PV for this very purpose. On a long trip, with hot ambient temps you'll find the "Performance" map makes for a much more comfortable ride. Sacrifices abit of mpgs for a cooler running engine.

That was my first thought. The pings started right after I filled up with 93 octane Mobil, from a very high volume station. My next fill up was Shell 93 octane from a station I've used many times. The pinging continued.
Could I have gotten two bad tanks? Is there a lasting effect from one bad tank of gas? Also FYI all gas in CT is 10% ethanol
Thanks

I also have an oil cooler, so I run pretty cool anyway. All that extra fuel for cruising seems wasted, but I am keeping both maps on the PV too just in case I venture away from the coast.

I'm guessing, but HD knock detection relies on ion sensing via the spark plug. Old or non HD spark plugs could contribute to the lack of spark knock detection. Its the ECM that reads and retards spark based on spark knock detection...I believe the PV is only reading the info from the ECM.
I've never seen a satisfactory answer as to the suitability/function of non HD spark plugs in the ion sense system, although some claim to use other plugs with no problems...but I've gone back to using HD plugs in my late model HDs just because I know the system was designed to work with them.
I do know that both you and Chris started seeing knock events with new HD plugs that were previously undetectable.

There are 4 "grades" of gas that are blended during the course of the year to accommodate different ambient temps (in the 4 season regions of the country). Summer time has less butane in the blend (avoid evaporation issues). Winter has more butane in the blend (evaporation not as big a concern in cold temps). Spring and Fall are halfway blends. The winter blend has less btu's per lb than the Summer blend due to the % of butane in the blend. The octane remains the same but the power and fuel economy varies from better in the summer to worse in the winter with Spring and Fall blends in-between.
I wonder if what you are experiencing is a summer tuned map that was close to the edge in terms of "knock" that is now displaying knock with the "Fall blend" of gas???
Any one have any experince with the Power Vision Black Visor and quick release? Does it hold up well and secure the PV well?
Thanks
Jeff
46u: I've been using both for over a year. The visor only works in certain sunlight angles; it does tend to move at high speeds (dependent on fairing, unit placing, etc.). I've lost the holding bolt/nut and had to replace with a suitable substitute from the local hardware; now secured with Loctite and nylon locking nut... no more issues with that.
The quick release works great. I've removed it daily, sometimes frequently when tuning, and on some trips not for days. The lower raised point that fits into the lower PV unit slot for holding it is beginning to show some signs of wear and I'm planning to order another one this week just to have on hand when if finally fails to hold securely.
