EFI Ignition

After all the discussion on after market ignition systems in the post on "mileage sucks" you got me curious. On my 86 302EFI, all my ignition is just stock Motorcraft. What are your recommendations? What is a PIP? I either pull my boat to the coast for speckled trour or redfish or pull a small trailer and go hunting off road. What is a good street setup?

Re: EFI Ignition

Geez my mistake

I was thinking of a high performance ECM, not PIP. The PIP is basically the pick up coil inside the distributor that reads the position of the 8 pointed rotor and tells everything else when to fire to which cylinder. The ECM is a little brain unit bolted to the side of your dist that acts in concert with your EEC-IV brain under the dash.

I had all kinds of grief this past year and replaced just about everything until I found out it was a nearly corroded through fusible link that quit whenever I hit a big bump.

Having replaced just about everything ignition related this year on my 86 I'm in a fairly good position to recommend what made a difference and what didn't.

Go with somebodies better coil. I went with an MSD Ford style TFI coil #8227. That perked it up and added noticably to the mileage. Like I said the actual MSD-6 unit didn't add as much to this truck as it had to previous vehicles I've had them on.

Once you get a bigger coil and better wires (8mm minimum) open up the gap some. I ran .052 with just the coil and now I'm running .060 with all the other mods. Of course the cap and rotor better be up to handling the new bigger spark. Like I said JET and Holley make hotter ECMs, but I've never used one so I can't say if they work.

K&N air filter, like was recommended to me by these guys, helps breathing. So does a free-er flowing exhaust.

That's all I can think of right now.

Re: EFI Ignition

I appreciate the input and the clarification. I have the K&N and the 3" freeflow exhaust and that makes a big difference. I'll look into the coil, wires, dist cap and rotor.

Re: EFI Ignition

He`s referring to the ignition control module,or TFI(thick film integrated)if you have the module on your distributor. I was considering getting a holley TFI but are the only benefits on the upper(above 6K RPM)range? or will they help out at lower RPMs?
Anyone Know?
