I've been reading about the distributorless ignition systems that Ford used on Explorers and other vehicles. I like the idea since I will be going to a MS stand alone computer pretty soon. I want to take advantage of the features the tunable computer can handle. One is discarding the MAF (simplifying). Another capability of the MS is that it supports a DIS/EDIS system. I know I will need a crank trigger and sensor for the signal to the PCM. It does not need a cam signal so the cam position sensor will not be needed but the cam synchronizer (it looks like a distributor without the top) can still be used without the sensor to serve as the oil pump driver. The system also uses an ignition module which fires the coils. I have read this is not needed but I also see that the PCM delivers 5 volts as the output for the ignition so I believe that is something I will need to verify. It's no big deal to use the module. I saw a system a guy on ffcars fabbed that looks much like I want. He used two 4 post coils. I wanted to mount them on each bank very close so it would be almost as good as individual coil on plug setups. The wires would be very short from coil to plugs with the mounting right off the valve cover.
I was wondering if anyone on this forum has done a similar project. One of the limitations on the Explorer system is that it runs at a constant 20 degrees. I belive that those references are with the system using the stock PCM so that is probably not an issue.
So chime in if you have experience this system and what do you think about it?
Thank you,
