The MSD's advantage if there is one will be more pronounced at low engine speed under 3000 rpm because that is the range that it multi strikes. Over 3K it goes to single strike.

At idle speed the multi strike hits it several times over 20 crank degrees so if it doesn't light it the first time it gets a few shots at it. This helps get a cleaner idle on engines that have cams with a lot of overlap.

oooooh yes.... believe it! I do, because I have being there!




Aren't you the one who takes them apart and fixes them?



he is indeed! but i think he fixes them because it's too hard to get stuff in his country. it's easier to fix what you have or found. i also believe when he wrote his thread about doing that that he determined heat was the number one issue with the internal components. now why do they get too hot? you'd have to ask the crowd who runs them with no ballast.

Forgot about that crowd.

I've still yet to have a Mopar ECU crap out on me. I'm patiently waiting and it's getting a bit frustrating to be perfectly frank.

I had a mopar ECU go bad in 1976, my car sat broke down for 4 or more months until my uncle helped me figure it out.


Then I don't remember another going out on me since.

I have like 6 or more ECUs from cars I parted out. I found that a OEM one from the early 70s runs better than the chrome one I bought in the 2000s
