volumetric efficiency tables - speed density metering project

Does anybody have the volumetric efficiency tables for the 12A engine?
I'm planning on converting to fuel injection and I was going to use a speed density metering system.

Yark! there is some misinformation out there...

VE is very close to torque, get a torque curve for your engine and then base the WOT VE on that. There is a program on the MS site that automagically calculates a table for you based on the torque curve.
