I have a Power Vision datalog question I could use an explanation .
Under
- Datalog
-Datalog Settings
-Signals
There are Four options
-Manual
-Auto General logging
-Auto Narrowband logging
-Auto Wideband logging
I can't find anything that explains what the differences are or why you might use Manual instead of Auto General or Auto General instead of Wideband.

Anyone able to shed some light I'd appreciate the insight.

Thanks

I can't help you with the other types of data logs other than to say you wouldn't use wide band unless you had wide band O2's. The following was from his how to.

http://api.viglink.com/api/click?for...13703059094148

• MAP (Manifold Absolute Pressure)*

• ET (Engine Temp)*

• Warm-up AFR or Lambda*

• TP (Throttle Position)*

• Engine Speed (RPM)*

• VE New Front*

• VE New Rear*

• Accel Enrich*

• Spark Knock Front*

• Spark Knock Rear*

• Desired Air/Fuel (Ratio)* or

DesiredAir/Fuel (Lambda)*

Later versions of Log Tuner may also require:

• VE Front*

• VE Rear*

Add these if using autotune for both AFR and Lambdabikes/calibrations

• Lambda 1**

• Lambda 2 **

* From H-D data bus

** From Auto Tune (when equipped)

Still trying to figure out how to set the AFR table to something higher than 13.3 in the 80KPa column in WinPV. Anyone? Could it be because I don't have wideband O2 sensors?

when you click on a cell with your mouse it turns blue ( highlighted, just like the one in your picture) at that point you should be able to type in whatever afr you want.

if you press and hold your control button when you start clicking on cells you should be able to highlight multiple cells, then whatever afr value you type in will be entered into all the highlighted cells.

AFR target values shouldn't have any dependancy on Wide/Narrow band sensors. I did a quick check with WinPV and I was able to edit the 5000/80 cell and had no problem putting in a bigger number. Of course I didn't try and write the file, and my PV wasn't connected. Can you elaborate any more on what fails and when it fails?

Thanks.. there is a link to Justdennis instructions in post 3844 of this thread, page 385. I've read it a few times and set up a log using the Manual option. I can't find anything on what auto general, auto NB or auto WB are used for. I do have the WB module and sensors, so if I was going to use one of them I guess it would be either Auto general or Auto WB. So far I've only been tuning with PV autotune, still working on getting my VE's 2% and under. I've still got some 4-5-6% in high RPM low load cells. Once I get VE's done I want to set my Lambda's to all open loop. I know how to do it but not what values to use in various load/RPM ranges. I want to use 14.2 in the cruise range and then I'm iffy. Once I set Lambda's (AFR's) then I want to work on timing tables. I think Datalogger might be better than autotune for timing tables but can't wrap my head around how to use it. Unfortuneately I'm a walk me thru it side by side a couple times learner. Reading it, interpretting what I've read and implementing it does'nt play well with me. My learning style doesn't work well with the internet a lot of times.

When you do an AT with narrow band sensors it sets the entire Air fuel table to 14.6 to 1 on a temporary basis. When you are done with your AT run and you flash the AT to your ecm the air fuel table is back to where it was.

Actually I am the one that was confused. From what I was reading on this forum, I thought AT set all values to 14.6 and left them at 14.6 (full closed loop). Thanks for clearing that up. I couldn't imagine why anyone would want to do that.

Generating that kind of heat is a bit of a strain on your motor for extended periods of time. jamie also recomends 20 to 30 min tuning runs. i was doing the first 2 like that but then i started running an hour. so.....i almost had to take stock out in blue gone.

With the wide band you deffenetly have a less stressful situation on your motor while tuning. I think it is done at 13.1 to 1 or something like that. Kinda funny though how i have seen many people post and in articles that the bike will run as lean as 14.8 or even 15 to 1. Different stroke for different folks but i would not be comfortable running that lean at all.

i assume (there is that word again) that for the new versions selecting the auto narrow band logging setting will work just fine for those of us wanting to experiment with log tuner

I think you mean Log Tuner. If so, then it's actually pretty easy to use, and it will correct timing. it does timing corrections in small increments (~2deg) so you may have to make several runs to trim your timing. Just monitor the Deltas in WinPV until you see very little change.

There are step by step directions for Log Tuner on the Fuel Moto web site at:
http://www.fuelmotousa.com/site/pvlogtuner.html
Follow the directions one step at a time until you are comfortable with the process. It's not difficult.
