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

[joecar]

Why would you not just use CALC.W02BEN instead of CALC.SELBEN?

That is another way of doing it... you would replace every use of CALC.SELBEN with CALC.WO2BEN...

i.e. the Data for the MAF map would be CALC.WO2BEN, and in CALC.VET the use of CALC.SELBEN would be replaced by CALC.WO2BEN.

OK great, my NB O2s are crapping out on me.

Help I cant find the tunning pids???

[Tinbender59]

joecar i am getting an error message, could you point me in the right direction? EFI won't come up now??

Error code: ERR_CONFIG/92

C:\Users\Lloyd\Documents\EFILive\V7.5\User Configuration\calc_pids.txt(47): Units /(5.669()*{SAE.RPM}*{SAE.MAP.kPa})*{CALC.LTFTBEN}" not found. .

Post your calc_pids.txt file here so I can look at it.

thanks Joecar, I did go ahead and download the pid file from this thread post #1, and reloaded EFILive, seems to have fixed the issue. I do not know what the heck I did, I was able to get one VET data log then the next day problems problems problems. here is the bad calc pid

[joecar]

Ok, yes, use the calc_pids.txt file form Calc_VET thread post #1.


(the file you attached above has some extraneous text in it which will cause the scantool to complain as you posted further above).

I've read all pages of this thread and I've also had an issue with the calc.ve table values being all 0.0 and the pid for the engine disp says nothing. I've tried to manually change it under the edit tab and no luck. I'm also messing with a supercharged engine using the efi custom os for 2 bar map sensor does this calc.vet table work for both individual maps >105kpa and <105kpa or could I make a custom map from 5-160 and combine them? Also does the calcvet table control afr at the instances or just reads how much air it sucks in at those values. I'm looking to set up diff af ratios for diff boost levels. I've posted a log in a diff thread and having serious ping issues with this truck. Under wot SAE.KR never sees more then 6 degrees and yet still pings and broke a piston

Use g*K/kPa for VE units (in V7 tunetool, go Edit->Properties and set VE units to g*K/kPa)(i.e. avoid using % units, because % units requires displacement).

Yes, it works for both VE tables (<105 kPa, >105kPa).

Calc.VET procedure corrects MAF table and calculates a new VE table... neither of these control AFR (or more specifically, neither controls commanded EQR).

MAF and VE tables determine the calculated airmass... then commanded EQR (AFR) is looked up (either stoich for CL, or from PE table if enabled)... i.e. airmass and commanded EQR are separate.

Also, avoid AFR for fueling units (it does not consider what fuel you run)... instead use EQR (in V7 tunetool, go Edit->Properties and set fueling units to EQR)(in V7 scantool, log the pid GM.EQIVRATIO... and discard the pid GM.AFR).

Only post #1 is the "tutorial" (follow all of the links it contains)... the rest of the thread is merely discussion.
