Thanks Abe. If I try an EFI system, I’ll certainly need some assistance. It sounds like you’ve been working with the electronic systems for a while. I know that the EFI’s have fewer mechanical parts than a carburetor, but it’s NOT the mechanical parts that are hard for me to understand

Tell me, how do you “tune” with a computer? Do you plug a wiring harness into the EFI’s computer module and then into a USB port on your PC computer? Do you buy software that is specific for a particular manufacturer’s engine, like a small block Chevy? And how do you program the different setups between a radical 383 and a stock 327? Are you optimizing the fuel mixture based upon the exhaust sensor’s readings? I’m assuming you’d need to put the car on a dyno to tune for power.

If you’ve done all of this, give me a brief lesson in what the process is (real world).

And what about all of the wires for the sensors (like Streets complained about)? Are they two wire (pair) connections, or does the setup require a large wiring harness?

If I go with an EFI setup, it would probably be something like this Hilborn setup... and even if I figure the operational stuff out, I’ll still have to convince my wallet that the expense is worth it
