problems with CALC.VET

[Tinbender59]

I am curently trying to get my truck tuned, but. the "data" for calculated VE, not corrected, - Calc.ven is reading "0" what am I doing wrong,
here are the pids that I am using, should be everything that the tutorial said to use??? 22729

However, LTFT's are running -1.8 to -4.3 TP and Load are running 26% to 45% pretty much neck and neck. Timing was 26 degrees on up hill to 36 degrees on the flat. Around 70 mph @ 2100 rpm the faster the better.

is calc.DAT putting out data? Some OSs don't support that PID and you have to create a CALC.B4901 too for CALC.DAT to give valid data....which in turn is required for CALC.VEN.

post the datalog and calc_pids.txt

[Tinbender59]

Ok will do

[Tinbender59]

here is my current tune and a 30-ish mile scan. On the previous iteration, I did open up the timing, Was limited to 16 degrees, and added 5% to VE across the board. this round, opened VE another 3%. However it does look like O2 2-1 is laying down on me, I have one ordered it will be here Monday. I also have the trans shifting way early, for MPG assistance, she has the torque to handle it. when I go into "tow haul" everything is as stock tow haul for pulling.

she does run real "clean" smooth and strong, I'd just like to get it correct.

Edit: I just looked at my pids, they were all Imperial, switched them to metric??? maybe the problem??

Can you post your calc_pids.txt ?

Located at C:\Users\YourUser\Documents\EFILive\V7.5\User Configuration

[Tinbender59]

yes sir, here you are. thank you

it should be the one from the calc thread

[aaronc7]

Looks like it's working fine for me, so long as you choose VEN in g*K/kPa units (NOT percentage). As the guide talks about, using the default units is preferred and makes it a lot less likely to screw something up as well. Just change the tune software to display default units in the settings.

See screenshot below, you can see it's working using default units, but showing zero for percentage units. I think you need to set your engine displacement in the Scan software if you want to use percentage units.. never done it myself personally.

Cool, i say that everything was in imperial and wondered about it. Thank you again

[aaronc7]

Units wont matter-- the program can convert easily between all of them and will use whatever units are defined in calc_pids.txt. Glad it was easy fix

[joecar]

In the log file in post #5 the pid CALC.TRIMMING was not selected.


Otherwise looks to be working good.

[joecar]

Log shows knock, find out what is causing it.

[joecar]

I use kPa for MAP, g/s for MAF, g for cylair, g*K/kPa for VE, EQR for fueling, and everything else is Imperial.

Well I cant find this??

[aaronc7]

I'm assuming he means calc.trimming = calc.cl

[joecar]

I'm assuming he means calc.trimming = calc.clYes correct, I stand corrected

( CALC.TRIMMING is in a newer calc_pids.txt that I'm working on )

[Tinbender59]

Thank you

[Tinbender59]

ok I just checked my PID's and its there "calc.cl"

Joecar have you gotten your new calc_pids figured out, I would like to give them a try on this stubborn beach!!

[Tinbender59]

ok I think that I am narrowing in on this issue. there are two different tables (or threads on Calc.vet)

first is here https://forum.efilive.com/showthread.php?16413-Calc-MAFT-correcting-VE-and-calculating-MAF-(in-single-log)-gt-reverse-of-Calc-VET

second one is here https://forum.efilive.com/showthread.php?15236-A-New-Twist-on-CALC.-VE-Table..Computing-the-Entire-VE-Table.

understand that I have troubles dealing with something that I do not completely understand (at least understand the basic mechanisms of the issue) so as such, I searched out everything to do with calc.vet and built a hard file (printed everything out, and put in a binder) then I study and incorporate it all into a cohesive document, and start from there. could someone explain the differences in these two threads? please? I have! figured out that I should have used one or the other, but I do not understand which one to use.

P.S. I wish That I understood "basic" language programming!

Post #1 in the Calc.VET thread contains almost everything you need (follow the links you see in that post).

Doing Calc.VET is easier than doing Calc.MAFT... Calc.VET is very much like doing AutoMAF (except it addtionally calculates a VE table) (and using EQR and Lambda instead of AFR).

This is a whole new can of wax that you may regret... :)

Cool thank you, noisy lifters are back, SMH

Will do thanks
