Just letting everyone l'm starting on a system using servo motors or solonoids to electronically actuate the VDI and 6 ports. I have the sleeves removed right now, simply becuase it's better than wiring them open- I have no air pump. I don't want the air pump, because I don't want the parasitic drag- I actually noticed a difference when I removed it.
I want a functioning 2 stage system- the way it was designed. I don't have bad torque- but it could be better- the bottom of gears after a shift kindof sucks- so does exiting a corner at the bottom of second.
I will definatlely be making some sleeve inserts (Like pinapple racing) too.

I will let eveyone know of my progress- I am looking at the most cost effective way- You shouldn't need any RPM activated switches or anything like that- The ECU supplies eveything that's really needed.
Hope to have some results and intructions up soon.

 

Are you gonna sell the system? If so, I am down to buy one! If not, just hook us up with a how to.

 

I don't have enough free time to fabricate a system to sell, I will however, tell you how to do it if you pay me!!
Just kidding. I will post my plans once I have debugged everything.

 

Word of advice, Pinapple racing sleeves are VERY inexpensive...they may cost you less $$$ after adding & subtracting all expenses. Concerning the air pump, I don't think there's a drag at all but if you felt an improvement after taking it off, more power to you. Have you thought of using a electric air pump?

As you said the ecu supplies all signals needed

 

The ECU only supplies the info needed on Series 5 engines though, right? 86-88, don't have solenoids for the 6-ports, or do they?

 

nope, 88 and below uses backpressure from teh exhuast to accuate the ports, though i have heard of people using the EGR soleniod (or some other worthless one your rip out) with an RPM switch to activate them
