Fuel Moto
thanks for the replies and for taking up this problem again
I want all here to know this problem was caused due to dyno jet updated the power vision format and screen but did not put out any new info or instructions for the update
when I contacted them I kept getting referred to the old videos which did not match what my unit was doing
I can understand they deal with these every day and a simple change may not mean that much to them but to some one like myself that is going to follow instructions to the letter it makes a big difference
I want all to know fuel moto has contacted me again about this and they are going above and beyond to try and help me understand how to use and operate my power vision

thanks again to them

Thanks for the follow-up. Buying a PV from FM was a very smart move!

Good on ya' for clearing that up here.

hello again
just to make this clear it was not fuel moto that I had any problem with they are doing the best they can to help
most of the conversations/email was thru dyno jet they kept sending me outdated instructions which was getting me more confused and frustrated
just wanted to make that clear to all

For those interested FM University is now live, there is a University tab in the upper right corner of our website. This is an info & resource portal with tech info on tuning products, engine components and more. You'll find FAQ's and video's and content will be added as we move forward. There is a bunch of Power Vision content. Check it out at https://university.fuelmotousa.com/hc/en-us

 

Good afternoon to all,

I'm new to the tuning world and recently purchased the Dynojet Powervision. After installing the preloaded map for my configuration ('14 FLHTP w/ SE Slipons and Big Sucka), I noticed a significant drop in mpg and the rpm/gear ratio seems to be off as well.

Has anyone else experienced this or something remotely close to it? If so, how do I fix it?

 

Best option is to get it dyno tuned, if not you'll have to run the auto tune.

 

WinPV includes the smoothing function and getting the table smooth is easy and kinda satisfying to do so using it must be intended but after 2 long days of collecting my own AT files I am poring over them in WinPV. The bike is running really sweet with the last version of the AT Tune so I could just close the PC, take out the WBO2s, remove the AT/PV/cabling and just enjoy the bike.

Base tune was a PV Dynojet tune with great results but I had to change the exhaust system so decided to PV/AT PRO myself as target AFRs etc were done by the DJ Dyno Tuner so I would only need VE Table adjustments necessary to achieve the AFR's with the new airflow characteristics. This process went really well and I enjoyed turning cells on the green screen red and targeting different zones of the screen per AT run.

BUT as i can never leave anything alone I looked at the files on WinPV and I see these "odd man out" cells. I am going cross eyed trying to see if the same cell in every tune is like this using the compare tool but in reality, this venture is only worth getting into if the answer to iClicks question is clear:

Big 2Qs: are these cells "odd man out" because:

1. The bike system determined those cells need that VE as a fact so don't mess with it

2. There will always be spurious cell values due to changing conditions, bike system artifacts (fancy words eh?), or control input surprises (snapping throttle open or closed etc). Its fine to smooth these odd values away.

I have tracked back to the thread post quoted from 2011 and a lot has been learned during the life of the thread since then - anyone now able to answer #1 or #2? (please don't say "both", that is the same as a non answer)

Cheers all

 

Are the cells you are looking at ones that did not reach the PV AT "hit count" setting limit? (default is hitting the cell 5 times)

Are they below the minimum VE learn setting?
Are they above the MAX VE learn setting?

 

Hmm - you could be on to something there - can i see a table for Hit count so I can correlate?

I believe is a minimum not maximum number of counts set to 5 right?

They are not above or below the max min VE learning setting

Thanks for your help

 

I don't remember seeing hit counts in the PV files/logfiles.
Yes the min hit count default is set to 5.

You may also be seeing PV data where one of the log items was not retrieved for a record, "missing data".
Maybe the RPM or TP didn't get put into the PV log.

Do you have MegaLogViewer?

You can load a PV log file and display data, RPM vs TP and VE, it will show the cell count from the log. (you would need to make the RPM / TP axis columns match what is in your VE table.)

You can see the hit count (in the data details on the lower left) from the highlighted cell: (the four cells at the bottom right have "missing data")
