calc.vet without wide band o2 please help

[nick123]

ok so new to tuning
trying to do calc vet
when transfering selbens over to tune file dosent work

17143 paste and multiply by 50% seemed to work but why???

[joecar]

Are you following post #1 in this thread: Cacl.VET thread (https://forum.efilive.com/showthread.php?15236-Calc-VET-correcting-MAF-and-calculating-VE-(in-single-log))...?

If you have no wideband, you have to edit the CALC.SELBEN pid in calc_pids.txt to always use CALC.LTFTBEN.

In your maps, you forgot to include the units on the axis (in map properties, on Col and Row tabs, checkmark Show Units).

[nick123]

yes calc.vet thread
ok got maps changed !
how do i know what lines of code refer to selben.... maf vs. sae.rpm??
or do i just delete the wbo2 parts ???1714617145
can i rename it?? dumb question ...probably not...

[nick123]

can somebody help?? what exactly should my calc_pids.txt look like??
would it really matter since i have no wbo2 there is no input from that...
do i just delete clc 00 220 ???!!
im a tradesperson not much programming background.
thanks in advance!!

Joecar has already told you what to do.


If you have no wideband, you have to edit the CALC.SELBEN pid in calc_pids.txt to always use CALC.LTFTBEN.

[joecar]

i.e. in calc_pids.txt change this:



*CLC-00-220
factor 0.5 1.5 .4 "iff({CALC.CL}, {CALC.LTFTBEN}, {CALC.WO2BEN})"



to this:



*CLC-00-220
factor 0.5 1.5 .4 "iff(1, {CALC.LTFTBEN}, {CALC.WO2BEN})"



using a non-formatting editor (e.g. like Notepad, and not like Word).

[joecar]

And of course, you will have to filter out all data for which CL is not 1 (i.e. with LTFTBEN only, then only the frames for which CL is 1 are valid).

[nick123]

thanks for your paitence joecar17172

[nick123]

17173 should i add displacement per cylinder here ??? there was a drop down list selection at one point but i forget where it was... and if it had changed any thing. 5.3 LM7

[nick123]

thanks buddy real helpful don't comment again please keep it to yourself
Joecar has already told you what to do.

[joecar]

Where you have "iff({1}, ...)" remove the br aces from the 1 so it is simply "iff(1, ...)".

[joecar]

No worries.

He's ok, he assumed you knew how to edit CLC's (which is a fair assumption).

[nick123]

ok i think i got it 17174
sorry if i offended any body...
so the displacement issue... i have 2 trucks one is a 5.3 and one is a 6.0...
do i just change displacement per cylinder in the brackets in the calc_pids.txt every time ??
or do i use whole displacement of all 8 cylinders in litres or cubic centimeters ???
where can i find in depth info on editing clc's ???
also when i updated there was a dropdown list that let me select displacement cant remember how to get back there or if it was a perminant change

so like the pic above???
sorry so many questions...

No... use VE units g*K/kPa... using these means you don't need displacement.

[nick123]

No... use VE units g*K/kPa... using these means you don't need displacement.

great! now its starting to make more sense looking at the math on calc_pids.txt
this is quite the learning curve...
now to do some logging...will report back soon.
thanks agian for your help joecar

ok so heres a few pics of my maf adjustments171961719717198the first pic is after i pasted and multiply
second pic add average % of LTFTs 9000hz - 12000
ok so the last pic is it all smothed the paste and multiply dosent work ???
is this because the rpm in scan tool and rpm in tune tool???
now to mess with idol cuz it wants to stall...
and reset fuel trims...
does this look ok?

[joecar]

The drop down of the MAF table from 9000 Hz to 12000 Hz has to be manually applied to below 9000 Hz, which the third pic looks like you have done... if the MAF continues to be a smooth monotonically increasing 4th order polynomial curve, then it is correct.

When you get that error, it means you copied without labels.

[QUOTE=joecar;208722]The drop down of the MAF table from 9000 Hz to 12000 Hz has to be manually applied to below 9000 Hz, which the third pic looks like you have done...

When performing a Closed-Loop MAF Calibration, normally only those MAF frequencies below 7000-8000 Hertz are adjusted. This leaves the MAF Frequencies above 7000-8000 Hertz totally 'uncalibrated'. A technique to estimate the upper portion of the MAF Curve is to add the Average of the LTFT1 and LTFT2 Banks (LTFTAVR), and apply that percentage to the upper portion of the MAF Curve. If done correctly the entire MAF Curve will have the same slope from 150

do you mean above??? the upper portion right from 9k to 12k??? or apply the LTFT average to the lower portion???

copied with labels then paste and multiply with labels...
allways get this dono why??

[joecar]

Are you using both LTFT and wideband or only LTFT...?

[nick123]

172071720817209here are my map properties. only LTFT edited calc_pids.txt like you said earlier...

[nick123]

aaaha now i get it 17210

[joecar]

I can't view your attachment ("invalid attachment").

[nick123]

ok so now... can i run calc maft with no wb??
when i run calc maft i use my calc vet corrected VE map??

[nick123]

17232
pids for maft
cant find pe mode pid for some reason??
found it calc.cl replaces it...
the maf corrected map on narrowband??? col row should be what exactly

[joecar]

Yes, using CALC.LTFTBEN, but first you have to do this:
- edit the transient filter to exclude all data for which CALC.CL is not 1,
- edit CLC-00-220 in calc_pids.tzt to use only CALC.LTFTBEN;

edit this:


*CLC-00-220
factor 0.5 1.5 .4 "iff({CALC.CL}, {CALC.LTFTBEN}, {CALC.WO2BEN})"


to read like this:


*CLC-00-220
factor 0.5 1.5 .4 "iff(1, {CALC.LTFTBEN}, {CALC.WO2BEN})"

pids for maft
cant find pe mode pid for some reason??
found it calc.cl replaces it...
the maf corrected map on narrowband??? col row should be what exactlyYes, the newer Calc.VET replaces CALC.PE with CALC.CL... make sure you use the newer calc_pids.txt file.

Post #1 in the Calc.VET thread shows you how to make a MAF map (goto B5001, do copy-with-labels, go back to map properties and for row and col do Paste labels).

pids for maft
cant find pe mode pid for some reason??
