123 Ignition Distributor Timing Curve, Curve for carbureted 2056 Options

[SteveNMaine]

I am looking for the basic timing curve settings for a 123 TUNE+ 4-R-V-P distributor for a dual 40 IDF carbureted 2056.

I have been all over the different forums and really looking for more specific information for my build.

Thanks.

Here are some of the standard Bosch curves. I'm running 2056 with IDF 40s and I've programmed in the 050 curve; I find that it makes excellent power.

To the OP, I'll add my current and total advance amounts we are running on our 2056, if you think it's relevant, because it's got a Mallory Unilite distributor and not a 123 distributor.

Very interesting on the 050 advance curve (which is a distributor I ran on a VW years ago). IIRC it worked and ran well.

Questions:

1. If you've programmed in 30 degrees of total advance, where is your initial advance set at? What's your CR?

2. Are you getting any pre-ignition (pinging) with all this advance on your 2056?
