I like a lot of base timing, and I use 28 at idle conditions. I'd be curious if your engine combo would like a simulated "manifold" vacuum advance condition. Right now it simulates a "ported" advance.

I see your "mechanical" is all-in by 3000. I usually liked that a little earlier on my engine when I ran a standard HEI. My normal around town cruise rpm is 2500-2600, so I like to have cruise timing in at that point - 42 degrees max for me. But my rpm breakpoint is 3000 rpm, so I have to do a little blending to get more high vacuum cruise timing. If I had more granularity in my system, I would go for more cruise timing like you have, somewhere close to 50.

I would be curious how your setup would respond by pulling in your wot timing from 3000 to 2500.

Isn't this fun? You can play around without spring changes or vacuum advance cams and tension screws!

That's all that the handheld lets you access Get your ProCal software running and you can control the cells between that are interpolated.

The PI distributor software is still has more resolution than the FiTech tables, but not nearly as much as the handheld imputs would have you believe.

From the table provided above, it looks like a good safe starting point. You may find it wants a bit more timing up top, for the timing to come in a bit sooner and it may tolerate more low load timing.
