What table "xxxxx" is the command afr for what map pressure
Commanded EQR:
- OL: B3605 or B3647 for COS.
- PE: B3618.
Do use EQR rather than AFR (set tunetool fuel units to EQR), you will find it easier...
CL will be EQR 1.00, and PE should be EQR 1.17 for NA, and EQR 1.25 for boost (regardless of the fuel you run)
( you view the tunetool tables in EQR, you log EQR and/or Lambda from wideband )
( you do have to set the stoich AFR in table B3601 )
( for example, stoich AFR's: gasoline 14.7, E10 14.2, E85 9.6 )
The truck in working on doesn't go into PE like it should. It stays in CL under WOT and removes fuel under boost when the whipple ecm is adding fuel. I've got another thread somewhere with the tune posted and data logging file if you would be up for examining it for me ?
Post your tune file/log files.
Point me to your other thread...
using this method, if the car will be open loop, i need to modify the CALC.PIDS as said above. wich one will be the input data to correect the maf? and wich one will be the input data to calculate the VE MAP
If you're running OL (no CL) you'll be using WO2BEN only (no LTFTBEN)...
so you must edit calc_pids.txt as follows:
change CLC-00-200 from this:
to this (see the red zero):Quote:
*CLC-00-220
factor 0.5 1.5 .4 "iff({CALC.CL}, {CALC.LTFTBEN}, {CALC.WO2BEN})"
( This forces CALC.SELBEN to always use CALC.WO2BEN for corrections. )Quote:
*CLC-00-220
factor 0.5 1.5 .4 "iff(0, {CALC.LTFTBEN}, {CALC.WO2BEN})"
Use Notepad to make the edit (when you exit Notepad click Yes to save the changes).
You now proceed as said in post #1 (use CALC.SELBEN map to correct MAF, use CALC.VET map to make a new VE).
When doing this tuning I have followed all procedures and Im getting corrected MAF and VE table as expected. The only thing that is throwing me off is how choppy my AFRs are looking while logging. Im assuming this is because I'm doing CL tuning using this method. The up and down swings correlate perfectly to the switching of the O2 sensors. Would it be better to do this tuning using OL so that fueling isnt so choppy? Or is it a function of the wideband I'm using (AEM analog)? Or does it not matter as it is averaging out over time?
Post some log files.
LTFT's are a filtered from STFT which are filtered from NBO2 swings (i.e. they should not look choppy).
Well that's what I had thought. Maybe it has something to do with the wideband I'm running then. Eitherway, here is the log, my tune file (VE table updated more recent than the log), and my setup file.
I appreciate you taking a look.

In closed loop, the pcm constantly switches the fueling between rich and lean. Your wideband is only seeing what the pcm is doing. If you don't like to see that, then go open loop and tune with the wideband exclusively.
I'm going to be using this method this upcoming weekend and trying to set up all the stuff prior to the weekend its a 2007 L92 with 6L80 and I'm using and E38 with
OS 12614088 the
The B4901 is not in my OS. and this OS is Not listed in the ls1 os's.
does anybody have an idea on how to setup the B4901 table with a os that does not have that map ?
E38 would have a different table id for B4901...
are you trying to do this with E38...? Correcting the MAF will be easy, but calculating the VVE table will require the calc pids to be edited (not sure how yet).
Ive got a l92 with 6l80 inside a jeep and we're trying to make it smog legal and correct the fuel trims. The engine is bone stock as is the exhaust just the cold air intake is a smog legal kit from gm and the LTFTs are positive 22 something isn't right and unsure if just correcting the maf will fix this issues or is there something wrong with the VVE table skewed
Correct maf and vve tables. Or easier. Do a maf only tune with o2s and youre good to go
You will have to correct MAF and VVE separately...
Correcting MAF: disable VE (set dynamic airflow threshold to zero/idle rpm), disable CL/LTFT/STFT, use wideband.
Correcting VE: disable MAF (cause/force immediate MAF DTC), disable CL/LTFT/STFT, use wideband, use VVE documents (see below).

Whenever I apply the filter as listed in page 1 all the data becomes invisible any ideas ?
I think I had it say "include" instead of "exclude"
All thought the second I save the vet datalog and click on it again the map readings go way out of Wack. http://images.tapatalk-cdn.com/15/04...edf54b0877.jpg
Like 100kpa while logging they read accurately then all of a sudden they turn into reading that are wrong so I have to change the data on the map into the ven instead of vet to make any type of accurate change
Post your log file and your calc_pids.txt here...
which V7 software build version do you have (go Help->About)...?

I want to see your filter...
BTW: in the map properties, on the Data/Col/Row tabs checkmark Show Units and click Save.
Post-cat positioning of your wideband should not cause it to read lean under load.
Well I know the sensor was after the cats at the collector and the sensor bung was welded upside down so idk it moisture was giving a fake reading but it never had the issuer before only after the car and it's was only at 85kpa ish and above so under load im guessing cats are getting hot and working and removing hc/fuel from the exhaust stream and making it appear to have a hight O2 content making the sensor read lean. But that's just my guess
So Im totally lost on setting up the PIDs for this. I have a 12593058 OS so they arent setup for me correct? im not sure how to st them up Im lost.Attachment 18293 Thats my tune if someone would like to help me out thanks

For starters read a little closer your OS is one that works with the pid. There shouldn't be any errors with this method unless you didn't set it up as this thread is stating. But make sure you save the calc_pids. In the documents/efilive folder too
Sorry I must have glanced over it that's right where I was looking to. To many numbers in a row and I missed it. Thanks for the help
I problem I have the feb 2015 programs and used the setup as listed in post one and it works just fine with the 8.1 I messed with. Just go to your properties and change the default ve data to the gm/kpa instead of %
I had issues with the calcvet table building the data properly with the % due to the "displacement" area in the actual txt format of the pid
Use g*K/kPa rather than %
(to use % you have to tell the scantool your engine displacement as explained in post#1 of the Calc.VET thread)
Please work thru post #1 of the Calc.VET thread carefully and methodically (print it out, and check it off as you go; also follow/print any links it points you to)... this is not just the Calc.VET procedure, but it shows you how to setup maps, explains about DAT, and gets you to think in Lambda or EQR (rather than AFR).

Thanks Joe I'm still working on setting it up. Iv read through it several times and taking my time.
No worries, take your time :cheers:
