You can only adjust spark advance and air/fuel ratio. Like altering the advance curve in a distributor (something we have been doing for over 50 years) and changing carburetor jets and air bleeds, again something we have been doing for over 50 years. Biggest difference is the air/fuel ratio can be adjusted every 500 RPM or so. That, and no dirty hands. There is no magic there. I've been in business since Feb 1972, other than the incremental fueling adjustments, and incremental timing adjustments (very little-to-zero gains there if everything else is right) there is no power advantage to EFI computers.
The newest stuff is just crazy under-rated.

Ed,
Can the computers on these cars be adjusted cylinder by cylinder for things like retarding timing providing a better launch where a carb/distributor combination cannot?
