I decided to go all in at a low RPM mostly to see if I could get good MPG while cruising, not ideal for WOT.
The ignition control is a lot of fun! But once you get things dialed in it's hardly worth messing with.
Still running well!

I currently set mine to
22 initial, 36 Total, Start at 1000 and all in 2000. Vacuum at 10. Cruise is at 14.8 and WOT is at 12.8 a/f ratio. Runs really well and I may up the initial up to 25 degrees. I have tried 37 and 38 degrees WOT and it responds well but I decided to leave it at 36 for safety and to continue using 87 octane.
I also noticed that max timing stops at 42. And idle timing does not go higher than 26-29 even though its set to 22 with 10 vacuum. (run about 19-20 Hg of vacuum) It seems that the setting of 10 for vacuum only produces about 7 degrees max of timing advance. It reflects this also when cruising. Should be higher than 42.
My settings revolve around the way my gearing is set up. My transmission (200-4R) hits 70 mph at 1940 rpms (3.08 rear). So "all in" reflects that. The 1000 start reflects when driving around streets and overdrive hits, rpms drop to around 900 rpms and I can actually drive around 40 mph at 1000 rpms.
When I had my original distributor, my idle timing was at 36 with initial being at 18. This means I had 18 degrees of max vacuum advance. I miss that with this setup. I wish that they allowed more timing for vacuum. I will bring it up in my next phone session with Edelbrock.
Another thing I'm dealing with is my ECU does not respond to AC kickup. Edelbrock stated that it seems that all ECU's they have tested has the same issue. They sent me a new ECU and they are going to have me update the firmware to see if it fixes the problem. (Supposedly I will be the very first to have this Firmware even before it hits the Playstore. I connect with my Smartphone and Tablet.)
Do you use AC kickup (Pin out #7) feature?
