Info on FBO ecu unit

Hi Dave , good post . Do you know amplitude of GM pickup at some rpm and mopar stock pickup at some rpm ?
then we know dwell control rate from V/ rpm .
No need to reduce dwell until under ~ 3 k rpm to avoid coil overheat is why , and how they can eliminate ballast R So may do nothing till that area down ?
I thought chip in HEI looked at time between pulses not amplitude but either can work . But if amplitude , you might be screwed up with wring mopar vs GM pickup volts .
By the way HEI is a lot better conceptually than mopar , so those saying “ just a hei “ are leaving 1 k rpm on the table . Nothing wrong with early dual point either from old dodge v8 to 57 . more dwell , i think 55 back fits A block ( shaft length) .
Saw a dyno test where msd died on dyno 56 hemi , guy put dual point and ballast R he had on it exact same HP right to 6000. Nothing electronic to punt , 400 still in pocket too
