VVC is variable rather than on/off like VTEC. It's a very clever system that gives up to 75 degrees adjustment in duration, though no change in lift.
Hmmm, in that case, you'd need to figure out how it's adjusted. You can quite easily drive a PWM or similar system from MS. Depending on how much work you want to put into it, you could rig up a 'scope to the MEMS ECU and observe what the standard ECU does to drive it and at what revs/load. Alternatively, I believe the Emerald ECU can control VVC.
Yeah it is different to the vtec as it doesnt just go on and off. Might be possible to measure the output from the ecu at different rpms. Do you think it would be possible to run it like a vtec so when it comes on it offers maximum duration and when it goes off it gives the normal duration? or would this give poor running
