Can anyone help me on making a VE table??

I have a base tune that was given to me but I need to work the VE tables a little and I don't know how to work the math to figure out the VE tables.

The car is a 93 Camaro, 383, AFR 195's, 58mm TB, SVO 42lb Injectors with a 242/248 @ .050 .582/579 w/ 113LSA and 10.7:1 comp.

This is a different car than what is in my Sig.

Thanks

 

Have you Googled "magical equation"?

 

Why be a jerk?

Is there a site or anything that can help me create a VE table?

The Camaro also has LT's, no CAT, EGR or AIR system

 

He is about right. I have looked the world over attempting to find a mathematical way to calculate VE. I have not found it yet.

I have taken the equations that I have found and attempted to back calculate the VE of the stock tables but have come up with the incorrect answers.

 

Then how the heck do tuners do it??

They just don't whip # out of their ***!
There has to be an equation or something to tell you how to do it based on your upgrades?

 

not sure if it works on 93s but VE master will do all the work for you. do a search on here and you'll find the link. Basically you just import your log it reads it and cpits out a new tune with the ve table re worked. Doing it by hand is a pita. You have to look at your log for RPM MAP and the fuel trims. Then you get an average of the trims for the MAP RPM combo then use that to modif the corresponding cell. For example if the avereage if 5 on the you would multiply that cell by .95. The monodax website has a good write up on it. Your best bet would be to see if you can use VE master.

Thanks for the help.

I'll check it out.

 

Have you tried VE Master?

Use VE Master only if you trust what your 02 sensors are reading. Otherwise you will be chasing your tail. I run a open-loop tune only, because all I got is rubbish from my 02 sensors.

For idle:

Set to about 50% VE around 700-1100 cells @ the Kpa you idle at. Monitor this with a scanner. You should me making at least 10 inches vaccumm at your idle rpm. Kpa will rise by 5-10 when in drive. Raise VE about 2-4% around those new cells.

Cruise/Part Throttle:
Anything between say 1200-1700 rpm I lowered about 5% from factory settings. I left cruise alone, I only phased the numbers to where cruise Kpa is versus factory. The table should shift to the right with a bigger cam. You will have to play with this one if you have cam surge.

WOT:
You should max out your VE table around 3500 rpm under 95-100Kpa. Any adjustments after that should be made in the PE Table. I have as much as 28% increase adjustment with a XE230/236 cam (351 RWHP), I get a max injectory duty cycle of around 82 percent with SVO 30#'s. These adjustments should be monitored at the dyno.

In Open Loop, I lowered the Open Loop % per KPA tables between 7-10 points below 85 kpa, and zeroed out above it. I did this to insure it would not affect dyno tuning using PE Table. I wanted a linear PE Curve when tuning.
