Billy Boats - that's how they all work. It's physics.

Better words.
With a distributor, once your pick up is triggeredm you can only delay time (or send close to real time) to send electricity to the spark plug.

You can't really send electricity to the plug before the pick up is triggered.

So again, any electronic box with a timing curve only does so by retard degrees.

Works out the same way, so no biggie really. Just helps to understand how it really works....as you have found out.

He did a good job in my eyes. Put the timing at idle to 45* smooth's things out very good. Just pull it out fast as RPM comes up.

Running a MAP sensor with this ignition is the way to go with a blower. While dyno tuning my new engines I found that at WOT (6500 rpm) my engines make best power and lowest EGT with 34 degrees of timing. But at Peak torque and high load situations 34 degrees was detonating. Now with the MAP sensor the Daytona box reads boost and rpm and adjusts timing accordingly.
Example. Idle in canal, under 1200 rpm , in vacuum 38 degrees
Rolling onto plane, 3000 rpm , 4 lbs boost , high engine load, 26 degrees
Cruising up on plane, 4000-5000 rpm 0 boost. 36 degrees
At this point as the load on the engine increases the timing retards
These are not actual statistics of my timing table , there are 128 data points to fill in to program this table and the ignition box fills in the rest

Does it have knock sensor?
We found on my 598 41* made best power on dyno I run it at 39* in the boat. I cranked the timing up to 45* at idle turns it in to a ***** cat and lowers cylinder pressure makes the exhaust much quieter.

Was this with 93 pump gas?

Yes 93 pump gas. 10to1

Schweet.

And there is one of many benefits of programmable ignition.

I'm sure he did. My first response was confusing to read. You posted while I deleted it and typed a more clear post. What he figured out was what I was saying to others..so they would understanbd how electronic boxes give you advance or retard. Not many would know this off the bat until they sat down to figure it out. So my response to me quoing him wasn't all directed to him. Tough typing vs talking in person.

Was just looking at the EFI there is 961 cells for timing and fuel management.
THAT WAS ON A HOLLEY DOMINATOR ECM. The fast ECM has about half.

I too am thinking about purchasing these to replace my current setup. Which is a locked MSD pro billet dist, with crane boxes. The crane boxes have been great, and I have had no issues with the engines as far as detonation or anything. However, the start retard, additional timing at idle, and being able to customize the curve esp with the map sensor, is a total win all the way around.

Billy Boats, I'll give you a shout this week to catch up on things and talk more about your setup.

That programmable timing control/adjustment sounds very interesting...especially the idle control part of it.
