Edit: is not being able to sue the most efficient form of supercharger made good enough reason for uprev to release this or not? who in there right mind is going to make a kit that is impossible to rune without having the software to back it up?

Why can't you have a positive displacement blower? Is the problem constant pressure? Couldn't you just use a bypass or clutch type engagement?

Anway, the stock VVEL settings are probably more forgiving for any blower than a turbine anyway -- blowers aren't built in exhaust restrictions.

God I hate how this VVEL is a black box that we just have to live with

I have read this elsewhere.

For the electronics savvy, the simplest way is probably to figure out what voltages various VVEL sensors are looking for to vary lift and valve timing and then just condition those signals by splicing into the ECU wires. Thus, no tuning code would be needed, and in theory, the ECU would "think" it's operating as normal. That's essentially how piggyback VVTi and VVTLi controllers like the Camcon and V-manage work.

So... the million dollar question is: Does anyone have the VVEL ECU wiring diagram, the schematics for the VVEL sensors, or know anything about their operation, voltages, resistance, etc?
