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.

-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.

-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).

Temp related shift in VE tables
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.

Getting a tune into WinPV
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?
