Reply to "Ultraflow EFI Intake Manifold"

Guess work? Maybe.

OK Kelly, save me the guesswork. What CPU do I need?

I am guessing that what I need for my happiness with the system is my existing distributor, already curved for the Webers and a processor like the Haltec (can't remember the mofel) to control a TPS system.

I wouldn't even know how to approach a speed density system with a IR EFI.

With a TPS system the fuel maps can't be any worse then the Webers mechanical system are.
Presumably a lot better because they are much more detailed.

Incidentally, Webers are easier because you tune mechanically to individual points in the rpm curve. Call them road markers if you like.

With a CPU you have greater control, but you have to fill in all the empty boxes in the graph that you physically can't do with the Webers and therefore don't.

Changing chokes on Webers isn't tuning per say. You don't tuch any of the jetting at all. The size of the chokes change the torque/hp curve.
It's like changing the size of the tubes on the exhaust system.
