Power Vision Information Thread
@Fuelmoto,
I'm not dis-satisfied... Just wondering. In the past I have left the HITS screen on so I could see the PV working while in AT. I would see the WHITE BOX info come up and at stop signs etc I could see the RPMS till registering. So I felt that the AT session was working.
BUT when I had issues where the WHITE BOXES quit appearing on the HITS AT screen and the rpms stopped showing up on that same screen I didn't know if the PV AT session was still working. So that particular AT session I deleted.
My comment was not to cause issue or point blame as much as to ask - IF the gauge features quit working per the run of the wire and position of the PV on said bike... would that mean that a given AT session if you are running one would be compromised? My thoughts are if the gauges still show activity the wire is run ok and no problem. BUT if the gauges stop showing data there is a glitch somewhere?
I may do the procedure you outline and refresh my unit. What could it hurt? As said mine appears to work better with the ferrite traps on the cord. AND when I AT, not often, I put the PV in my left side saddle bag in a towel and it's never froze or stopped functioning.
Thanks for the great support and for the replies you make on this board!!!

I have not actually witnessed a gauge freeze when in Auto Tune mode or seen it any any customer logs however if you see gauge freeze when monitoring normal channels on the gauge screen, it is very likely going to do it when you are on the Auto Tune (green) histogram screen as its using the same bus data. When there is data stream loss it will simply not populate hits or generate corrections, this would also not actually compromise the tune session as there would be no hits populated during that time, the PV looks at the data as "all or nothing", when the gauges resume it would simply continue to accumulate corrections.

Good question and i'll explain further

I admit my choice of words...compromised the AT tune...could have been better stated if I had said "short on data". Meaning if you are not watching the PV unit and don't know when it froze or stopped getting data the changes may be minimal during an AT session that it could make if it had been live the whole 30 min session. Plus is it really safe to be watching the screen for constant data stream instead of riding anyway???
If you rode around for 30 mins in AT and the unit stopped working 10 mins into your ride...the changes it could make thru HITS would not reflect the whole ride time.
Thanks for the clarification and reading and replies Jamie!

Actually the term compromised was perfect as there is the potential for abnormal things to happen when the data gets interrupted. One example I have seen is if you are using the Auto Tune Pro kit and the wideband data gets interrupted by either having the CAN cable get disconnected or if the AT unit has a bad connection, i've see crazy things happen in the logs.

A freeze or interruption of the gauge screen is the same phenomenon; an interruption on the data bus for various reasons, most commonly RF interference from another electrical source thru either the cable or the actual PV device. For example, when tuning with the PV on the dyno I have the Power Vision unit mounted on my keyboard stand and in literally thousands of hours and many, many bikes I have never had the screen blank out or freeze. I have however seen a few bikes with the PV mounted that have noted the PV gauge blank out either briefly or until restart. In every application I have seen firsthand I have re-routed the PV cable and/or moved the Power Vision from one side of the handlebars to the other, done a full recovery & firmware update and it resolved it 100%, but truthfully I've only seen this phenomenon in 3 or 4 bikes ever. If anyone ever has this issue try the full recovery and all the updates I noted earlier, then try temporarily as a test put the PV and cable in your saddlebag, in your jacket pocket or whatever just test it completely away from any ignition source and give it a go.
Last question, on a full recovery, does the factory turn originally hidden saved to the device remain on it? I know how to save and recover any of the other 8 slots, like the one I got from you.
In WinPv select Get Tune and save the appropriate tunes from the Tune Manager, these are .pvt files. For the Original stk. file every time you connect your PV to WinPv if it sees there is not an original tune stored to your computer it will prompt "would like to back up your Original Tune" if you select yes it stores the tune in the following directory; Computer>Documents>Power Vision>Original Tunes, you can also manually save the original .stk by going to Get ECM data and save it to the location of your choice. After the recovery is completed to restore your tunes you will select Open then select the tunes and hit Send Tune to send them back to the PV device, to restore your Original Tune .stk you will go to PowerVision>Diagnostic Test Functions>Send Original Tune to PV (if you have backed the tune up on your computer) or choose Send .stk to PV (if you saved it manually)
vehicle speed in log viewer isnt working right
Why is it when I review my log on megalog viewer my vss only goes up to 4.97 now? I locked at some old logs from a few months ago and it was registering the correct speed then. I even changed out the vss for a brand new one and still nothing, but have never had a problem with the speedometer.

So, I have read most of this thread. Lots still to learn.
Has 222 cams, SE air filter, Rush HO header and RCX mufflers.
I have done my AT runs and VE tables look good 2 spots were above 5% but everything else was below 5%. Changed my AFR table for economy in the cruise range. Messing with decel enleanment currently.
It appears that I have some spark knock in front cylinder. Not sure how to fix it. Document is a graph from Powercore software and I attached the last log run.
I hope someone can put me in the right direction. Let me know what you think.

They have a shielded cable, I received a REV 6 cable this did not fix the issue. so I did a full recovery on the powervision, thanks to Fuel Moto's instructions. I will get out on bike in the next couple days to see if this fixs the 6 gauge mode from blanking out

Got the bike out for a 2 hr ride and thought the problem was solved but 3 minutes from the house the gauges went blank. I now think the issue is in the bike but have no way to figure out such an intermittent issue that doesn't throw codes. I give up and PV is no longer mounted on bike.
