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

[devlmaycry]

Okay, I've been slowly getting this set up to tune my car. However, once I select all of my PID's I have one that isn't valid.

BEN selected from WB or LTFT {CALC.SELBEN}

Expression:
factor = iff({CALC.PE}, {CALC.WO2BEN}, {CALC.LTFTBEN})
is NOT valid because:
Unknown parameter {CALC.PE}, at position 14.

PID value cannot be determined because
the following error would occur:
Expression not valid: Unknown parameter {CALC.PE}, at position 14.

Any idea on how to fix this?

Hi devlmaycry,

In post #1, the calc_pids.txt file has been updated (CALC.PE has been renamed CALC.CL), so download it and copy to the User Configuration folder.

Then, when a pid is not valid and it lists other pids as being unknown, then those pids also need to be selected, and so on for those pids;
for example, you show CALC.SELBEN being invalid because CALC.PE is invalid; so goto CALC.PE and select it; if CALC.PE fails to be valid, then repeat the process on it (see which dependendt pids it sees as invalid and select those also).


(note that in the updated calc_pids.txt file, CALC.PE has now been renamed to CALC.CL)

Ok, changed the one PE reference in that txt file and it fixed the issue. I had been in that file before changing the wideband formula since I have a V1, but didn't think to reference back to that file for that PE issue. Thanks again for all the help!

Cool you're welcome.

Ok, I'm sure I am just missing something small but when I log it just shows 0.0 in the chart for the blocks it's hitting. On my tune I see in the top right that the VE units are % so I chose % when setting my map up. I also have one set up as kpa, and it shows the log values in the chart as 1.1 etc. So, like I said I'm sure it's something small that I have overlooked, but I can't seem to figure it out.

When VE % shows up as zero, then the displacement has not been entered...

A. Set Displacement: open a Log File, go Edit->Log File Information->Vehicle Options, and next to Engine enter the displacement in cc, click Ok, and save the log file. This matters only if you're planning to use [%] units for VE.

I had a few other things selected in there. I cleared all the fields and selected only the 6.0 in there and it populated correctly.

Here is an alternate calc_pids.txt file that separates DAT out as a separate pid: calc_pids.txt

This file has pids for both the Calc.VET and Calc.MAFT tutorials.

Hey guys, currently i'm still using the old Auto.x because I get stuck in my ways sometimes I'm working on prepping to do Calc.x tune and I just want to clear some things up.

From what i gleaned it appears that the Calc.ve method, correct me if i'm wrong:
1. you run an all maf tune
2. the ben corrects maf
3. the method calculates the ve table
4. if 2&3 above are correct then why is there a Calc.maf?

[joecar]

The Calc.MAF procedure is the opposite/reverse of the Calc.VET...

Calc.VET = corrects MAF and calculates VE
Calc.MAFT = corrects VE and calculates MAF

[ the hint is in the name of the procedure, Calc.VET or Calc.MAFT ]

Also, either procedure can be tailored to use wideband only (i.e. becoming like AutoVE and AutoMAF, but with the bonus of calculating the other table).
