Hey Mike any possibility while you are blowing barriers to the wayside and dropping untold amounts of cash that you could have GTM throwi in a motec M800 series ecu With the advanced functions for traction control and boost over run(wasted spark), Electronic throttle support with the multi throttle box, dual wideband support, an external knock box, Downshift blipping, variable cam timing, and the servo motor control?

Long story short hook up two servo brains to sensors on the back of the vvel sub-assemblies, and run their positive and negative motor wires to the standard DC motors on the sub assemblies. Then wire the motec servo out to the 2 servo brains and you have full vvel control as well as a standalone ecu that could easily handle all engine functions on your motor reliably.

After having talked to uprev i feel they don't ever really want to bring vvel out so the motec with a servo conversion on each head is going to be the way to go. You would need to have the throttles do all the air metering and then have the servo drive on the motec referenced to the rpm for the angle of the vvel system. I'm gonna go make a post in the tuning section this week to give a better explanation or just shoot me a pm but i figured out how to do it.

Edit: so long as you can control the throttle, cam timing, fuel and spark, you could use any kind of box that can create the reference signal for the servo boxes running the vvel motors, the motec just does all of it in one package.
