Good idea. Did it and it still reads WBF:L.
Also have a red light flashing on auto tune unit.

OK... I was expecting WBR:L if the sensor was bad. Did you swap the sensors or the cables? If you swapped the sensors and the fault stayed on the front cylinder, then you may have a bad cable. If that is the case then try swapping the cables (either end) and see if the fault moves to the rear cylinder. That would indicate a bad cable.

 

Guys I have ran some autotune runs and have flashed the latest. Where do I find and decipher the results and what is the numbers I need? Thanks guys

 

Download your last 2 tunes to your PC using WinPV. Open your most current tune in WinPV. Open the previous tune using Load Compare.

-You want to view VE's (under Airflow).
-Click on the Delta tab in WinPV. This will give you the absolute difference between the last two tune files.
-Observe both front and rear VE's
-When you get that number less than 3-5% you're good.
-Move on to look at timing if you like.

 

I've been using power vision with my fat bob - I have a stock bike with VH Big shots and an after market air filter. I've run Basic AT a couple of times - what does this table show? Any thoughts?

 

With the bike running and cable cut loose from bike, I went along cable bending it and sure enough, started working on front. Cut back covering and wire was broke. Soldered up and all is well. Thanks for walking me through it.

That's a typical VE table.

-Load the previous map using Load Compare
-Click on the Delta tab in WinPV. This will give you the absolute difference between the last two tune files.
-Observe both front and rear VE's
-When you get that number less than 3-5% you're good.
-If greater than 5-6% you need to run more autotunes until the deltas come into range. Always compare your final run to the run immediately prior (last 2 runs).

 

Anyone else done more than a little AT spread across a wide temp range? Say 35F - 90F?

Have noticed here that _peak_ VE (highest 3 - 5 cells) tends to be 5 - 8% lower at < 40F than it is above 80%,

and that (centered on around 65F) the pattern stays the same, but the main hump tend to shift a cell or 2 up/left on the cold side and down/right on the hot side.

 

So, I've searched and played with WinPV for an hour or so and can't seem to figure out how to get my PV tunes into WinPV.

In WinPV, I go to...

PowerVision, get tune from PV..

Pick the tune I want and hit OK...

Get a message "Tune is ready for editing"

So, I go to Open, navigate to the "tune files" folder I created and nothing is there?

Feeling stupid here...what am I missing? Where is the tune being downloaded to?

 

I see it's already in WinPV under tune items...lol

sorry...

I did an hour or so auto tune today and am wondering what the data is telling me. If I post a pic of the air/fuel ratio, can you folks tell me anything about it?
