Opinions on my test VE table..inside I have been working for hours assembling a VE table based on data that I logged through HPTuners today. There are some manifold pressures that I did not get...I would have to dog the vehicle for along time to get them all, so the parts that didn't pop up (that I doubt pop up frequently at all) have been scaled based on my stock VE table. Can somebody take a look at these and give me some opinions before I just dump it in my cars computer?

Hmm.. your VE table seems ok around the very high RPM/Loads area but all else seems extremely low.
Here is my VE table you can use for comparison. I am a NA stock internals car with no MAF.
Plz note, this table could damage your vehicle. Use at your own risk. I accept no responsibility for anything you do with this table.

I would give you my opinion but the HP Tuner values are much different than the values in LS1Edit. Where you have 90 I have 2247. Is there a conversion formula? MAybe Edit value / 25?

Thats a peculiar stock VE table...of course it looks far more normal than my stock one. What did you smooth out? Anything?
I don't know about that 2247 where my 90 is in the VE table...my HPTuners pulls a VE calculation, in percent, directly from the car. I thought it was rather unusual myself. That is what I calculated my VE table from, based on calculated VE, rpm, and MAP.
Anybody else have any input?

don't use the VE PID to calculate your VE table. I used the LT's for much of mine but ideally you need a WB02 and a load dyno (or lots of street time).
My WOT VE is a little high I believe as I have to pull the PE vs RPM down quite a bit to achieve air/fuel ratio that I am satisfied with. My VE with a 1 PE vs RPM multiplier would run me very rich.

If you wade through the sticky VE thread at the
top of this forum, you will come away with a
hurting head but maybe some better idea about
how Edit uses their number (it is some kind of
absolute air number, while HPTuners is a
percentage of ideal); if you knew the displacement
based ideal absolute number, that times HPTuners
percent should be close to that Edit cell value.

The values in the PCM are the same. The difference is how LS1Edit or HP Tuner chooses to display them.
What does a stock Main VE Table look like when you pull it with HP Tuner?
If you do not mind could you post or email me a copy of it from your 98 Z28?

Magnus,
Just at a glance, your table looks quite high. Our 427 race engine wasn't that high in the mid range.
A VE table calculator and closed loop function was used to determine our table (Gen VII software).
Just my opinion.
