    80s Lean Burn distributor and Fitech EFI

    I have heard the twisting tip for the two wires to the distributor pickup. Those will only be used when I hook up timing control. Initial setup will be just the single RPM feed wire, and that will be shielded and grounded on one end. I have heard of people adding noise filters to tach wires...

    80s Lean Burn distributor and Fitech EFI

    Yeah, it is ultimately a janky solution to accomplish timing changes with "spark slop" between the rotor and the cap terminal. Mechanical advance physically moves stuff to change advance, and keeps that timing between the rotor and cap terminal consistent. There's no real way around that...

    80s Lean Burn distributor and Fitech EFI

    They do take a MSD phaseable rotor and have lockout? That's pretty rad. I will keep that bookmarked. I'm not necessarily married to timing control. The current plan is to at least see if I can get it running on the existing ignition to rule out fuel side problems before moving on to ignition...

    80s Lean Burn distributor and Fitech EFI

    Why does a billet distributor emit less EM noise than OE distributors? Seemed like people who had new MSD billet distributors were also running into the RFI challenges. With timing control enabled and the ECU using the distributor pickup instead of reading an RPM signal off the negative side of...

    80s Lean Burn distributor and Fitech EFI

    The e-core benefits are definitely there, but my understanding was that the controller (ECU, MSD box, whatever) had to have the necessary dwell control capability. Fitech sells their own CDI ignition box and e-core coil pairing. So it had me scratching my head why that product exists if the...

    80s Lean Burn distributor and Fitech EFI

    This was a misunderstanding I also had until I dug further into it. The Fitech ECU has the ability to trigger the coil and control spark. It can directly take the place of an ignition box. That black wire can ALSO be run to the "points input wire" on a MSD or similar CDI box to command it to...

    80s Lean Burn distributor and Fitech EFI

    I've got a box somewhere with a stock distributor out of an '87 Fifth Ave with a roller 318. I haven't dug it out yet, but should be single pickup and not the goofy dual pickup distributors from the earlier Lean Burns. That was what I had in mind.

    80s Lean Burn distributor and Fitech EFI

    Anyone ever done it? Seems like it should work, since there's no advance mechanism to the distributor at all, and you can skip any lockout plates, welding, disassembly, or having to buy an MSD distributor. Just the two pickup wires to the ECU and set base timing to spec with the computer. Seems...
