Ladies & Gents, TracyG, et all, would you please, give me your advice or point me in the right direction as to the following: (a bit of background info first:)
I have read and re-read "ignition secrets" and I have installed the Gadgetman grooved throttle body on my 3.5L V6 FI Mitsubishi Montero Endeavor, along with a MAPster between ECU and MAP. I am working on solving an O2 sensor as I am writing this and will put a resistor on the post CAT sensor, then tweak the MAPster, again.
My next step is to install a plasma ignition IAW Aaron's "ignition secrets." I have ordered a set of Granatelli zero-resistor spark plug wires (might be a couple of months before I get them) and 6 custom-made double tungsten plugs (might be a while, too).
I found out the Mitsubishi has a distributor less ignition system or "waste spark system" using three coils, each firing simultaneously in cylinder pairs, one in compression while the other one is in exhaust phase. My understanding with such is that one plug arcs positive to ground and the other one arcs ground to positive, causing opposite pitting of the electrodes unless minimized through use of denser precious alloys but most of all, it seems to prevent plasma from working on half the cylinders as the diodes blow on those cylinders receiving reversed polarity. (Please, correct me if this is wrong as I am not a mechanic and this is all new to me!)
Hence my questions:
1 is there a way around it? What is it?
2 can this system be converted to "coil on plug" system? If so, how?
3 I see
has an MSD DIS-4 Plus Ignition (PN 62152) unit that seems approved for 6 cylinder distributor less systems, BUT is specifically says it will not work with straight core plugs and zero resistor wires due to EMI. Of course Granatelli claims the doughnut on their wire addresses EFI and EMI both. What do you all think/know?
4 does this MSD change anything to the opposite polarities of the paired cylinder plugs?
5 Assuming I get the plasma going, either with the current distributor less setup or with a coil on plug or (fill-in with your suggestion), will the MAPster I am using in series between the ECU(PCM) and MAP be sufficient to tweak the fuel flow for the new hopefully more complete burn resulting from the plasma ignition or will I need a quad-band EFIE, further complicating things?
Thank you all in advance for your time and input/suggestions.

Please, forgive my sometime basic and naive questions as I am not a mechanic but I am willing to learn ...
PS: If one coil sends HV+ to one cylinder plug and HV- to the paired cylinder plug, is it possible to put a string of 25 diodes on each wire and have them in one direction on the HV+ and opposite on the HV- or not? say 1-4, 2-5, 3-6.
Is it correct to say 12V battery is connected to MSD and MSD connected to the three coils. If coil 1 does 1 and 4, coil 2 does 2 and 5, coil 3 does 3-6. Could we say have 1, 2 and 3 setup for + diodes and 4,5 and 6 setup for - diodes?
In his book Aaron Murakami talks about some MSD boxes not connecting the caps directly to the coil and using a "chopper" system instead, which defeats plasma. What might he be talking about and how do I find out whether the MSD-Dis 4 box is such?
