Multipler Method: The Decel Enleanment Multiplier is normally set to 1.00. The help description in WinPV says increase this will value will increase fuel. I think that is backwards but will check with DynoJet to be sure. Normally I change values by 10%, then try 15%, up to about 30%. If what DJ says is true (increasing the value = richer), I would start with 1.10, then 1.15, etc. I use the Table method below - I know it works.
I changed the DE Table from this - to this (reduced by 20%)
1.00 - 0.80
0.98 - 0.78
0.95 - 0.76
0.90 - 0.71
0.76 - 0.59
0.60 - 0.46
0.53 - 0.41
0.49 - 0.37
0.46 - 0.34
0.46 - 0.34
0.46 - 0.34
0.46 - 0.34
1.00 - 0.80
0.98 - 0.78
0.95 - 0.76
0.90 - 0.71
0.76 - 0.59
0.60 - 0.46
0.53 - 0.41
0.49 - 0.37
0.46 - 0.34
0.46 - 0.34
0.46 - 0.34
0.46 - 0.34

I always use the Table Change method described in the previous post not the DE Multiplier.

I was referencing the Decel Enleament Multiplier not the Decel Enleanment table itself. They corrected the manual and the description is correct for the Decel Enlenament Table in WinPV but I believe the Decel Enleanment Multiplier is backwards in WinPV. I sent a note to DJ to verify that it is incorrect and plan to revise the post once they respond. see attached

Can anyone provide insight as to how the MPG adjustment actually functions? There is a fuel consumption output from the ECM. Obviously, there is a built in odometer. Does anyone have a sense as to the accuarcy of either of these outputs? Or does the PV do the math to one or two inaccurate outputs and the MPG adjustment applies a fudge factor just to get the MPG closer. Just asking...

I would like to know what MPG adjustment numbers (values) everyone is ending-up with. My original value was 1989, as I'm sure many of you had the same original value. I made the change to 1790 (10%), but I haven't yet calculated whether I need to go further at this point. I'll be making a full fuel run this weekend, but in the meantime, I was just wondering what numbers you guys were coming up with. -Steevo-

Decel Enleanment Multiplier
I contacted DynoJet and they confirmed that the description of the Decel Enleanment Multiplier field is incorrect in WinPV. I updated post #900 in this thread to reflect this. They will correct the description.
In the meantime, if you want to richen the mixture during the decel event using the Multiplier you should decrease the DE Multiplier. If it is currently 1.00, changing to .90 will richen the mixture 10% during the decel event. I still prefer using the DE table as described in post 900 because it gives you the flexibility to change by temp.

This window exists mostly to correct these three MPG-related values, and the old gauges will still be available. No longer will there be the MPG Calibration and VSS will no longer calibrate distance. Viola! Keep your fingers crossed, as I'll be testing this today on an 80-mile ride I'm planning.
You can make corrections by touching a value, like Fuel Used, and then enter the real
fuel-used that you just got at the pump. It will then calculate a correction without making you use a calculator, which is very slick if it works. I.e., if the PV Fuel Used shows 4.0 and you fill with 4.2 gal., the correction will move from 1.0 to .95, or at least I presume that's the way it works.
