They are a business though which requires making money to fund other projects which might not pay off as well. The VVEL project is a high cost (R&D) with probably little pay off in the end for them.

Also, you can easily call up some machine shops and send them the specs on your exhaust cams and have custom ones made.

Heres the answer
 
I've been doing some search lately to solve our VVEL issue, I found this company online that offers complete CAN BUS software’s and Interfaces.
They also offer Engineering services maybe we can start a Group Buy and contract them to offer us new software for our cars I’m not good at negotiating so I will leave it to someone with a better idea of what we need to do the negotiations. Here is a link to their web page they look super LEGIT.

if i had something that could take the accelerator pedal position(0-5v) x rpm (square wave), and generate a pwm for servo control based on a 3d map, (preferably something that could also do cvtc cam adjustment stepper signal as well as run the ignition and fuel as a standalone for cheaps) i could make it work. hell i'm sure a motec calibrated correctly could do it but last time i priced one out that could do it, it was ~11k$ after the options required.

basically all that is needed is 2 hbridge dc motor controllers that can handle the amp draw from the vvel motors, i have two in mind, they have to have an analog position feedback control circuit integrated into them and they are about 200 for the pair after heat sinks, enclosures, wiring and POT feedback sensors maybe $400<----all that would let you move and control the motors then it all comes down to mapping the pwm signal and running the motor with a stand alone/wiring it all in to the car. I talked to sam before about it and he thought an fconvpro could do it, but it wouldn't be cheap AT ALL.

we have expensive ways to do it what we need is a cheap way i say we blind fold, tie up and beat the guys from uprev till they code out cvtc and vvel for us, the Mother F*ckers

Edit: also if anyone out there has mad bank and they want it now i'll send you some part numbers to take to a shop that could drop in a motec and for round abouts $15k plus labor you could have TOTAL control over every aspect of this engine.

Ya.. would be nice. So the initial thought is there are gains to be made through vvel? I talked to Christian
@ Cobb and he did mention there probably is power to be made through tuning vvel . Time will tell I guess

1slow370 10-22-2011 09:10 AM

my thoughts would be is there gains in cams+timing on an hr(our baby brother)? you bet your ***

Any progress on this one? would love to see this done
