That GReddy unit only controls fuel, right? Does it do so by manipulating the load (MAP voltage)? If so, then you'll still need to worry about timing. If it doesn't control it by altering the load, then you may need to run a second MAP sensor to that unit to control just the fueling since the stock one will only read to just barely over atmospheric pressure. How it'll alter fuel without playing with the load of the engine, I have no idea...

FCD's are nothing more then voltage clamps, with a resistor built in to cut the voltage by percentages (depending on adjustment). *shrug*
