    Two hours of tuning time this morning, she's really coming around. Apparently, have one flaky injector though. They are early '90s Ford 19 lb/hr off the same 4.6L donor engine that I stripped the throttle body & elbow off of for this flathead build; I'm surprised only one had issues. Buying a new set of Holley 19 lb/hr injectors this week. Happy camper though, that old flattie sounds evil.

    You need to run resistor spark plugs & resistor (non-solid core) plug wires. Be sure to properly gap your plugs. You also need to properly phase the rotor. Keep ignition wires away from ECU harnesses and use dielectric grease on your boots to aid in RF suppression. If you have RF and or EMI issues you need to correct them. They will result in driveability issues, including idle control problems, and could possibly damage the ECU. Have you ever watched a post nuclear apocalypse movie? EMI is what wipes out all the electronics. Magnetic pickup distributors are especially susceptible to vehicles with uncorrected RF & EMI issues."

I've got a clean functional connection to the laptop with the engine running now. That Gauge Panel display is pretty cool! Can't thank everyone enough for all the good suggestions. I've been using Holley EFI systems for almost two decades now, and the support is a big reason why.
    Thanks for the update. I'm glad you resolved that problem.
    May God's grace bless you in the Lord Jesus Christ.
