main VE table

[1sikmax]

okay iam new to this forum, ive done a lot of reading just never posted.
i have a 2007 NNBS gms sierra 6.0 L
i want to make a new VE table and get started on really dialing in my tune. i have a wideband o2 sensor already installed but i cant seem to find my main VE table {B0101}
under my "airflow" tab its a red folder :confused:
attached is my tune as of now
if someone can help me out that will be appriciated :)

EDIT: just realized i posted this in the wrong section.... someone please move it to either the gen IV or E38 section, whichever it belongs in
thanks

It should set you on the right path.
BTW welcome to the forum.
ps The red folders mean you can only view/edit these tables while flashcan is connected.

Welcome to the EFI Live Forum....
Glad to have another truck guy with a 6.0ltr V-MAX
Post up your stock tune and I'll help you-out
Also what Octane fuel are you using?

Have you made any tweaks to your Transmission?

Ya I've removed all TM, bumped pressure in the line up, engadged my tcc in second gear, reduced shift times, I can't remember what else iam not by my lap top iam on my phone in class haha
I can post it up when I get home if you guys want to critique it

[1sikmax]

okay i fallowed everything step by step untill page 7 where i had to go to
B8101
i searched it and it came up i dont have it :confused:
can someone help me out??
thanks

[5.7ute]

Do you have flashcan connected to the computer? If not you need to be to access this table.
If you use search with a higher number table open it will not search backwards & will just go to the end of the list. Hit search again & it should show up. Unfortunately I dont have my flashcan here at work so I cannot check your tunefile for myself.

I had it connected and searched again when it went to the bottom of the list
I don't know why it didn't show it doesn't make sence for me not to have it
And I tried connecting my wb02 but it cantfind it.. Are auto meter wb02's compatable?
Thanks

It's VVE table {B8101} not {B0101}
Here's a screen shot of your stock VVE table, I found it...:)
Make sure Flashscan V2 is plugged in before you open up the tune tool.

Okay cool thank you! I was in a hurry when I was trying to figure it out haha maybe I entered it in wrong on the tune just like I did on this thread haha I'll take a look at in in the morning
Thanks again

okay i was able to find it haha it doesnt come up for some reason on the tune i based off my edge evo but it comes up with my stock tune so i donno
oh well at least i found it!
thanks for all your guys help! i am sure ill have a lot more ?s in the next day or two

You're not going to be able to pull your Edge tune, ever. Since its not a tune, its a tricker box, the ECM/TCM are still 100% stock just their signals are manipulated by the box. You're starting from scratch here man.

When I pulled my level 4 ( only one I've pulled) it has a different high octane spark table and stuff I can't remember what else but it is different than stock

[ScarabEpic22]

Really, is the Edge officially a piggyback or a module that flashes the ECM? I thought they were just piggybacks...

I went through the same process of flashing the ECM when i would change tunes like I do with efi live so I don't know if that means anything in answering your question iam not familliar with the term "piggyback" but I think I know what you mean. The diesel might be a piggyback becuse you never have to "flash" the ECM like you do with a gasser with edge

[ScarabEpic22]

Piggyback= module piggybacks the stock ECM/TCM/PCM modules and modifies the signal that is inputted from the engine sensors before they reach the ECM/TCM/PCM. It tricks the stock stuff.

[1sikmax]

okay i fallowed step by step, did a run and loged some data, when it would idle to about 1500-2000 rpm the wb02 would be tacked out at 18:1 but once i got going it entered PE iam guessing and would stay around 12:1. so i did a quick log and figured i would try and adjust the ve table a little just to smooth out the lean-ness and then do some longer better runs so iam not surging as much on take off. i copied with labels and pasted and multiplied with lables and it was REALLY spiky! like it maxed out some cells at 10000!!!

[GAMEOVER]

Wow, all I see is WBO2 @ 25:1 AFR....
Command is 14.68:1 and then drops to 12:1

ya i have no clue whats going on.....:help2:
can someone look at my tune and see if i did something wrong???
thanks in advance

EDIT: EVERYTHING UP TO B2405 ISNT IN MY HISTORY FOR SOME REASON BUT ITS ALL BEEN CHANGED IN THE TUNE IF YOU GO TO EACH TABLE INDAVIDUALLY.

[1sikmax]

Anybody????

I KEEP GETTING THIS ZONE #12 TOO SMALL ERROR
WHATS THAT?

[GAMEOVER]

Your WBO2 data isn't right. What WBO2 sensor are you using? It shows 25:1 thru the whole log. Can you verify it's even working...Your data log's show a Ben Factor of 2.0:shock:
I looked thru your tune and you changed everything you needed to, per the VVE tutorial.

iam still trying to figure out how to hook up my autometer wb02 i have the tutorial (link afew posts above this) and ive copied/pasted the calc_pids into the user configration like said but its not working... i gotta keep messing with it. iam still in the learning process of this whole thing. whats the ben factor?
and do you know how i can get my error of "zone 12 too small" ive changed my rpm boundrys and it keeps popping up. and when i would paste with lables and multiply into the vve table in some cells it would max the efi limit at 10000
thanks

Ben Factor is the difference between Command AFR and Actual AFR(using a WBO2)

Okay cool looks like once I get my wb02 up and running I'll get that fixed .. Do you know anything about that error I keep getting about the ve table?

[Blacky]

The zone too small error is caused by a zone having less than three rows or less than three columns. Make sure all zones have at least 3x3 cells.

I have an Auto Meter WB in my car, too. Check your Auto Meter documentation, you can program the output voltage to reflect any AFR you want, it's called "BGD Range Setting Mode" within the gauge menu. Here's the info from Auto Meter, it's on the bottom of page 4:

http://www.autometer.com/download_instruction/1143A.pdf

You can scale the output, meaning you can have the gauge output 0v for 10:1 AFR and 4v for 16:1, 20:1... whatever.

So if the gauge isn't outputing the the 0-4v range to the scale that the calc_pid is expecting, it's going to be way off.

What is your calc_pids.txt expression that you're using?

The calf_pids.txt iam using is the one in the link on page 2 of this thread.. I'll mess with it some more right now I just got out of class and see what happens
Thanks! I'll keep you posted

[XcYZ]

"2.5 * {EXT.AD1} + 10.0" assumes the 0-4v output of the Auto Meter wideband BGD LO is 10 and BGD HI is 20. You need to verify that using the documentation that I linked to.

[GAMEOVER]

I think your MAP boundaries is what's causing your problems. {B8021}
try setting the MAP1 values to something like 28KPa
The values you're using is kinda low or better yet use your stock MAP values.....

[GAMEOVER]

Post up a screen shot of the VVE table your currently using....
Don't see these changes in your tune history,
I think you missed a step per swingtan's tutorial:

1. Go to B8101, press <F4>, select all cells and “copy with labels”
2. Save the current tune (after adjusting the previous 2 parameters) as a new tune file.
3. “Re-open” the same file, and go to B8101. It should look somewhat different to
previously if you have changed the previous parameters. Select all cells and “Paste
with labels” to return the VVE to a stock like map. Click on “Generate Coeffs” and
“Generate VVE” to complete the process.

This part of editing the VVE table is important:eek:

[Blacky]

Ya so how do I fix that?
See images.

after i would adjust the 2 parameters B8020 and B8021 and apply the stock vve map into it thats when it comes up like the picture #3
ill try adjusting the boundrys u pointed out and see what happens
thanks for all the help so far
ill keep you posted

[Blacky]

Note: After adjusting the map boundaries, make sure you save the file and then close and re-open it. That way the VE tables will pick up the new MAP boundaries.

okay just tried it and the x's are still there... ive coppied the calc_pids for the autometer into the user configuration i think iam missing a step somewhere???
thanks

[Blacky]

Do you mean the red x's are through all (or most) of the PIDs that you would normally want to log, or just through the wide band PIDs that you want to log?

If its just the wide band PIDs that are giving you trouble, then send me your calc_pids.txt file and I'll try and get it working for you.

its just the wb ones. i right clicked on them and clicked more info and it explained what other pids i need to select to validate that one so i did but i got to CALC.BEN_WB2 and it tells me:

BEN Wideband 2 {CALC.BEN_WB2}

Expression:
factor = {CALC.AFR_WB2} / {GM.AFR}
is NOT valid because:
Required parameter {CALC.AFR_WB2}, at position 15 is not selected.

PID value cannot be determined because
the following error would occur:
Expression not valid: Required parameter {CALC.AFR_WB2}, at position 15 is not selected.

how can i select the same pid to validate it? you know what i mean? i read that to mean select the same pid to validate it... am i correct?

[Blacky]

It means that the PID CALC.BEN_WB2 is dependent on other PIDs to be able to calculate itself. For the CALC.BEN_WB2 PID to calculate its own value it needs to have two other PIDs: CALC.AFR_WB2 and GM.AFR. You must select those two PIDs as well.

I think you will also find that CALC.AFR_WB2 will be dependant on one of the external AD PIDs: such as EXT.AD1, which you will also need to select.

*okay i went out loaded the tune in and took out my yellow wire on the maf.. I added 15% to the ve table to make sure i dont run extreamly lean.. Now i understand the truck wont like ideling but i couldnt even keep it alive... Im really lean..i killed my battery trying to get this pig started and running
(and i was already at operating temp)

*another question... On swingmans tutorial it says to run pe at a commanded 12.5:1 with a tps of 4% (30%-35% in real life)where as in the efi live auto ve tuning tutorial it says command a 14.68:1 afr
to me it would make more sense to keep pe out of the equation at this time.

*and also sense iam using an autometer wb02 when i go to map propertys editor window, which one will be the correct perameter for my autometer? Do i select calc.afr.wb1 because that is where my afr is reading correct on my data tab (f9)

sorry if this is confussing
thanks
dillon

[1sikmax]

and how do you validate the perameter calc.ben_wb1?
see screen shot

[1sikmax]

okay i got the above perameter working.. i hooked up the scan tool with my tune ive been running just to log data to see if my afr from my wb02 reads the same as what the cells say on the map... my o2 says 1.xxx and the cells are saying its getting .8xx-.9xx ??? so something isnt set up right. i copyed the calc_pids file thing for the autometer into the user confg. calc_pids file
so is something not exactally right in that file??

[joecar]

Which wideband are you using...?

Post your calc_pids.txt file.

Your posted images are very small, I can't see the details.

[1sikmax]

iam using the autometer wb02
attached is my calc_pid
it was the one i was told to use so my autometer would work.
thanks
dillon

[joecar]

Post some log files and some sceenshots showing the differing AFR/EQ/BEN's.

What are the afr:voltage points for your wideband...?
You calc pid file shows:
0V = 10.0 AFR
5V = 22.5 AFR
Does that match what your wideband claims to output...?

[1sikmax]

okay ill try and get on that tomorrow.
can you read over post #48 and maybe you will have some advice for me as well on those topics
thanks again

- Increasing VE 15% is maybe too much unless your mods dictate it;

- Set PE to stoichiometric, but set the last few columns of the OL commanded AFR table sufficiently rich 12.6 to avoid motor damage;

- Yes if your Autometer outputs AFR according to post #53 then select the AFR and BEN pids mentioed in the file in post #52.

okay ill mess around with that and get the pe set.
as far as my autometer calc_pids its the one you gave me joecar..
my autometer volts are set up 0v being 10:1 and 4v being 20:1
now dont quote me on that iam just thinking thats how it would be

That calc pids file above is correct for this afr:v range.

[1sikmax]

That calc pids file above is correct for this afr:v range.

so what do i need to change in the calc_pids file under user configuration to match the above afr:v range??

[joecar]

It already matches...

The AFR pid in your calc_pids.txt defines: afr = 2.5 * v + 10

so, plugging voltages into this equation, you get:
v=0V --> afr=10
v=4V --> afr=20

you said:

...
my autometer volts are set up 0v being 10:1 and 4v being 20:1
...
So your calc_pids.txt is good to go...:cheers:

[1sikmax]

Okay i did a log i had to add 20% to the whole ve table just to keep from running lean. Now that i have my data from the log do i copy that into the ve table i already adjusted 20% or do i copy it into my stock ve??
And also if i select the perameter calc.afr_wb1 in the scan tool i get the cells in regular afr (i.e. 14.6, 15.7 etc) but if i select calc.ben_wb1 i get lambda... Which one do i need to use to copy w/ lables> paste + multiply w/ lables into the ve?? And again which ve... Stock or already adjusted 20%???
Thanks dillon
attached are the tunes w/o the new log copyed and multiplied into them...i tried posting my log too and it told me it was too big

thanks

[joecar]

Hmmm... what mods do you have...?

In the tunetool did you set fueling units to AFR or EQ and not Lambda...?

The scantool ben map should be of CALC.BEN_WB1 which is an EQ multiplier (not a Lamda multiplier).

Hmmm... E67... have you read the VVE tutorial(s)...?


You preload the VE table (you did 20%), you flash this, you log against this, then you apply the correction to this...

i.e. you "accumulate" corrections.

okay ya thats what i thought, just making sure.
As far as mods its just just a volent (sp) cai, shorty headers, and dynomax bullet muffler....
And i switched my fueling units to eq so will that help out? It was in lambda
what does eq mean anyways??

[joecar]

EQR = stoich/AFR = 1/Lambda

Where stoich is the stoichiometric AFR for gasoline (it will be 14.63 or 14.68 depending on your tune file... see B3601).
