Ve maps 0.00

I have V2 I'm using OS3 with 411 ECM. I'm trying to tune in SD with MAF disabled. When I set up the VE maps its showing 0.00 I set the table up according to the CALC. VE Tuning by Shawn PID file was updated per direction.
I have units on, for all 3, VE is % to match watch in my tune file. I'm sure this is something dumb I'm doing? I went to the limits tab(not in the tutorial) and raised max to 200 but now I get nothing in any of the cells. The counts are working.


I have also noticed the more I look I've found 3-4 different version of auto VE tuning. Is one better than another for me?

I have 2000 Camaro, 2002 OS upgrades to OS3 in the 411, Autometer WBO2(PID is fixed). I need to complete the SD for my NA engine before I finish my turbo kit.

Post screenshots of what you're doing, and a link to the procedure you're following.

calc_pid file was bad. I couldn't figure it out. I'm currently tuning with LTFT/VE and correcting the VE, when I get it pretty close I'm going to switch over to full OL and use the WBO2 to get it to 95%. I think this is more logical considering I wont be using the MAF at all going forward. I've read many of your post and they have been extremely helpful. There is just so much information its hard wrapping your head around it all. I haven't did much tuning since LS1edit days.

Hey Jay,

Attach/upload your calc_pis.txt file, let me check it.

There's are a lot of ins/outs to know about, I learned a new one the other day.

I cant get it to attach

I would really use GM.EQIVRATIO (EQR) instead of GM.AFR (I've see GM.AFR miss some of the dips/rises in the PE table).

If your fuel is not 100% gasoline (it always has some alcohol in it) the you should get used to EQR and Lambda.

EQR = 1/Lambda

It makes fueling easier to understand, for example:
EQR 1.15 means 15% more fuel than Stoich.

Also, it is easier to member that the BEN is:
commanded EQR x wideband lambda

You can easily add lambda to your CLC-00-041 and 042...
you have to know the default stoich AFR or the lambda equation of your wideband, you would add a lambda units section to the CLC (right under the AFR units).

And then in your CLC-00-061 and 062 you would go like this:

"{CALC.AFR_WB2.lambda} * {GM.EQIVRATIO}"

where the .lambda is your addition to the CLC for lambda.

And you would log GM.EQIVRATIO instead of GM.AFR.

Remember: EQR 1.00 is stoich, EQR 1.17 is PE (NA).

Sub'd, also going to add a couple tidbits to the thread I just started.
