Just "test" installed the FiTech on the Charger with the 500" 400 "B" based stroker. Seems like it might work, even though I have very low vacuum.
First step was running in TACH mode with the existing ignition setup and getting the fuel part working.
Part 2 was installing a lean burn dist and trying that out.
Got it to run (on the "start" pickup), but I think the rotor phasing is off.
After re-reading the instructions, it looks like the "run" pickup will work?
The two pickups are phased about 1/2 terminal apart.
Not sure how changing the reluctor position would change the rotor phasing?

I ordered an extra cap, so I can cut it to see the rotor phasing.
