vac advance or not for FE Cobra

[lippy]

John,

I think it's easy but I'm pretty good with computers. You just need a PC and cable.

It does have some advantages over a standard vacuum dizzy. It is infinitely programmable and you don't need to rely on springs and a mech advance, it is more stable at high rpm, and you get multiple sparks.

PM me if you want more details.

I have been learning on tuning EFI. Most people focus on the fuel, which is important, but the timing map is where most of the power is at. When you look at the timing maps from Ford, they are more sophisticated than duplicating the old mechanical and vacuum advance. A lot has been learned over the last 50 years.

I think Lippy is giving you great advice. I would expect significant power and fuel mileage could be delivered with the unit his is talking about. Think of it this way. You would be gaining the better half of an EFI system.

Great info.

Olddog - can you expand on your comments related to the current Ford timing maps? I haven't seen them.

I worked at GMC Truck in the early 90's when they started using crank triggers. It was a dramatic change in performance and mileage over the distributors. I assume the automakers have made many more leaps since then.

-I am planning the next build and it will have the MSD 6530. It isn't much more to get the added flexibility.

Just proves you CAN teach an old dog new tricks.

Old dogs do learn faster than pups sometimes.
