I let log tuner do it for me, it seems to work really well.

 

If I don't hear any ping/knock I don't remove any timing. The ECM is set up to remove 8*. I try to make a mental note of my rpm and map if I hear any knock then let the tuner make the change. I might adjust the changes a bit.

 

Thanks Dennis,

I'm in the process (last 3 weeks) of retiring from my job.. so what little time I have had to ride I am just riding, but as I wind down, or right after I retire, I'll be all over this.

Thanks again for the support!

 

I've been lurking around this forum for a few weeks now, having recently purchased a 2011 FLHTCU and installing the FuelMoto 2-1-2 Header, FuelMoto Pro-Billet Air Cleaner, Supertrapp Stout mufflers and a Power Vision with FuelMoto custom tune.

I'm trying to understand how to set-up and run a datalog, since my bike has some deceleration popping and the fuel mileage has gone down the toilet (dropped from 43MPG @ 70MPH to 36MPG @ same speed.

Please keep in mind that while I'm an old Guy and sometimes struggle with technology or simple instructions, so keep comments or suggestions REAL simple.

Setting the Power Vision to Data Log appears to be straight-forward, either by selecting the appropriate signals or using the Settings function and entering the 6 digit code.

My problems seem to be on the computer side, working with WinPV and/or Log Tuner. Despite my efforts over the past 2 1/2 days, I haven't been able to view any of my data logs I'm running Windows Vista Home Premium - 64 bit Operating system.

When I installed the PV Log Tuner it was stored in C:\Program Files (x86)\Power Vision Log Tuner and there are two files: PV Log Tuner and PV Log Tuner 32bit. I installed the one marked PV Log Tuner (not the 32 bit).

When I installed WinPV, it was stored in C:\Program Files (x86)\Power Vision, along with 7 other files (WinPV-ENU.dbx, PVUpdateClient, etc.)

For some reason, the Drivers were stored in C:\Program Files\Power Vision, not C:\Program Files (x86)\Power Vision.

I set-up additional files on my computer in C:\Program Files (x86)\Power Vision for Stock Files, Tune Files, Log Files and Value Files. I went into WinPV, went to Setup, then to Options and entered the same values (file locations for the Stock Files Folder, Log Files Folder, etc. I also changed the value from Basic to Pro.

In order to keep from having to go back to the program files, I created shortcuts for the Log, Tune, Stock and Value Files to my Desktop.

Okay - I connect the Power Vision to the UBS on my computer, then start WinPV, then load the tune from my Power Vision into the computer via WinPV. I check VE (Front & Rear), Air Fuel Ratio (Lambda) and Spark Advance (Front & Rear). I then select File, Save Selected Values, Save in: Value Files (C:\Program Files (x86)\Power Vision\Value Files and I name the file 2011-96-JP212-001.pvv (because I have a 2011 bike with the 96" motor and am running the JackPot 2-1-2 header).

Then I open PV Log Tune, select Options (14.6, 60,185,288, Use H-D OEM O2 sensors for corrections and Use Cell Coloring) and press OK

I press the Open PVV button, which opens C:\Program Files (x86)\Power Vision\Value Files) and my file IS NOT there!?!?!? I then go to the Shortcut that I created for the Value Files, open it and once again, my file IS NOT there!?!?!? But what is this: I see a new message on the tool bar (Organize, Views & Burn) that says Compatibility Files, so I press it and Presto, my value file appears.

I then copy and past the file to C:\Program Files (x86)\Power Vision\Value Files but when go back into WinPV and attempt to Open PVV, the file is not there, so once again I copy it from the Value Files Shortcut and Open the file.

I can now Open Log(s) in WinPV, so I select and open one of the log files created on my Power Vision while running the motorcycle. In fact, I try all 6 of them. The Table show all ZEROS! I hit the Calc Tune button and still, nothing but ZEROS!

Can someone please tell an old Geezer like me what I'm doing wrong????

 

Pick one of the maps to start with and go from there. Comparing VE tables alone between two different maps doesn't really mean anything. VE Tables are just one of the things that make up a map strategy. Load the map, tune the VEs to your bike and see how it works. As a matter-of-fact, then you could load the other one, tune the VEs on it and see which you like better.

 

Ranger,
I'm not quite sure of your problem but for me I created a new Power Vision folder with subsequent related folders under My Documents. In WinPV, Setup, and Options I defined these folders to save my files to, I have had no issues doing it this way. The reason I did it this way was if I had issues with the WinPV software I could uninstall it without risking deleting my Tune and Log files. Hope this helps....

 

I can relate.

You'll need to have Excel installed or some other program that can read .XLS files. If you don't have Excel (included with Office) M$ has a free Excel reader and Google Docs is another way to read these files. You don't need to view the spreadsheet files in the tuning process, but I like to look at them since they show the parameter relationships in real time.

I have two PVV files I use when tuning: Start.PVV and End.PVV, both in the \Power Vision\Values folder. The first is the one you create before using PV Tune and the last is the PVV written by PV Tune that updates your PVT (tune) file in the next step. I overwrite these for every tuning session, as IMO there's no need to retain them.

I'm not sure, but the first thing I would suggest is to download and read Dennis' tutorial on tuning, which may help. If you want to email me your original PVT (tune) file, the PVV (value) file you created from the original tune, and the CSV (datalog) files I'll take a look at them.

 

Hey thanks Brother! (I mean that on a higher level, assuming from your icon you're born again.) You ever consider joining CMA? The fellowship is awesome and encouraging!

ANYWAYS! I appreciate someone taking the time to answer my concerns! I just started learning about "tuning" a combustion engine. Looks exciting! I program PLCs and industrial automation equipment for a living, so I hope to catch on pretty quick.

I found an article on the net that explained VE tables a little better. Before I understood, I figured VE was part of the "user tune" I'll call it. But come to find it's an actual measure variable that takes place in real time according to the engine's characteristics. So VE tables are more measured than calculated.

Am I correct in my thinking now? lol

On a side note, MAN do I look forward to the release of the new AutoTune software!!!

Thank you gentlemen!

 

Your assumption would be correct. Glad you found the forum and like the PV. Stick around, there is a lot of good information here.

Where did you find the article on VEs. May be worth sharing.

 

It's been quiet on the beta updates. I see the docs that were linked have been removed. Has anyone been in touch with the powers that be? When I get back home I'll be doing one more VE tuning run then begin with the timing. For those that have done it, did you set the max spark to 10 and how did it work for you?
