MSD E-curve Distributor Set Up???

BrianT said

Tom built my exhaust and we are gonna take a swing at playing around with the different advance curves built into the MSD distributor.

It's going on a chassis dyno next week and I'd like to get the timing sorted out before I start paying someone $100/hr to tune it and they just scratch their heads because they've "never tuned one with that distributor before".

Good idea.

One of the problems I found (noted in post above) that I had to remove 2-3 plug wires and rotate the distributor to get the cap off. This meant I had to loose my baseline timing just to change the dials for a curve change.

I have a 3 speed wiper motor that got in the way.

If you run into this same problem, I'd take the wiper motor off before you pay someone $100/hr to fiddle with that. It will really slow them down. Is the dyno guy familiar with that distributor?

I think there are some advantages to tuning it driving around town in the type of drive cycle you will be typically using the car. I don't know a dyno is going to catch an off idle light acceleration stumble. That's a typical stoplight to spotlight situation. And that may be more important to you than getting an extra 3 hp at 4800-5000 rpm.

Take great detailed notes of Tom's tuning. So if you want to go back to his tune, you can 100% replicate it. He's more accomplished than that machine with two spinning drums on it.
