Calc.VET: correcting MAF and calculating VE (in single log)

[ecir45]

First time tuner here. Used calc_pids from first post. All went well except CALC.VEN showed invalid.

More info showed:

Calculated VE, not corrected {CALC.VEN}
Expression:
% = {SAE.MAF.gps}*{CALC.DAT.K}/{SAE.MAP.kPa}/{SAE.RPM}*3445.2/displacement()
is NOT valid because:
Required parameter {CALC.DAT.K}, at position 27 is not selected.
PID value cannot be determined because
the following error would occur:
Expression not valid: Required parameter {CALC.DAT.K}, at position 27 is not selected.
Calculated VE, not corrected {CALC.VEN}
Expression:
g*K/kPa = {SAE.MAF.gps}*{CALC.DAT.K}/{SAE.MAP.kPa}/{SAE.RPM}*15
is NOT valid because:
PID value cannot be determined because
the following error would occur:
Expression not compiled

Added CALC.DAT pid to make the CALC.VEN valid.



My OS is 12212156. Using Innovate LC-2 serial wideband.

Did I use the right calc_pid text file.

You've selected ECT in Metric and IAT in Imperial... they need to be on the same scale. Change IAT to Metric and add CALC.DAT back to the list (it's greyed out on your list). See if that helps. Also select CALC.DAT in Metric

had CALC.DAT not selected to show in pic above that it makes CALC.VEN invalid.

So CALC.DAT is needed but not shown in pid pic in first post?

[statesman]

CALC.DAT is shown in your list but the little icon is greyed out... so it's not selected.

Ok, I added a comment to post #1 to include CALC.DAT.

More Info shows a clue as to what the problem may be.

I now added a comment to post #1 to include CALC.DAT.

hopefully this will help when you get to the pdf. Thanks

I pasted your pic into post #1 to replace the original pic, thanks

Would there be any benefit from running Calc.MAFT after using Calc.VET or is Calc.VET good enough at getting the VE table right. The only advantage possibly I can see is by using Calc.MAFT you could see how far you are off in the VE table in % instead of a calculation.

Thinking out the box since I have only done one Calc.VET so far and think my MAF is spot on but think VE Table probably needs some refining.

You could (and probably should) run all the different airmass estimators at the same time. This way you can track if/when any calibration or parts are starting to diverge from each other. Also, it can drive you insane, because they will never be perfect, and you'll just end chasing your tail forever. Just a warning
