HI Jay,
You should buy one and put it in one of your cars and then write a review for us. I bet it would work great in your '63.

I was discussing this with 101 Alfa Mike last night, and he pointed out that 123 now offers one of the features I was wishing for: a distributor that can be connected to a PC so that you can load a custom advance curve. See:

123ignition electronic ignition systems for classic cars

The write-up even implies that they offer a version for an Alfa. Hmmm

Yes, as was previously pointed out in post #12.

What seemed more interesting than user-defined advance is the ability to switch between two user-defined profiles on the fly. Didn't dive into the details but it appears to have a dedicated signal wire (guessing here) that can be wired to a dashboard switch, or maybe triggered automatically off of another sensor/switch. Seems pretty powerful and opens up some possibilities.

I always that sooner or alter someone would do this. MSD has a programmable MDS6II box which will drive a distributor but 123 has turned things around. With Megaspark's public domain software, this is a cheap way to get a thoroughly mapped ignition. The only drawback with the 123 is that it's an inductive discharge ign. Wonder if it will work with an MSD6?

I have a 123ignition distributor firing an MSD6AL. It has been working well for several years. I don't need the programmable feature. The "006 tuning" (Jim Karamarlakis) curve works very well with my motor.

Whoops, yes you did. Sorry, I read your post, but didn't understand what you were telling me.

Yea, that's how I interpreted the text on the 123 site too.

I downloaded the software, and played with it a bit. It appears to make it very simple to create and store advance curves.

I wonder how it is priced?

Apologies. Tried to be terse (and spare everyone unnecessary chatter) but apparently too much so.

The link in post #12 is to Classic Alfa's offering listed at ~$445 USD.

Yea, I see it now. Classic Alfa sells the programmable 123 for $444 USD, and the older version for $363 - a difference of $81. Gee, when you consider all the entertainment you'll get out of playing with different advance curves, that extra $81 works out to only pennies per hour!

A custom advance curve that doesn't advance or hang up at idle. Just the right amount of advance through the mid-range. And, if you get the programable vaccum advance unit, an opportunity to get improved drivability and fuel mileage. Definitely pennies per hour!
