I have been readin through a ton of threads and seeing references to different products and ways people are tuning thier different F/I setups. Seems some people have reprogramed ECUs and fuss with fuel pressure to dial in a setup, and others are screwing around with add-on boost controllers.

What are the different ways being used to tune a F/I 350Z ?

Speed

 

A: Mechanically alter the fuel supply system to change fuel pressure characteristics at various points depending on alterations made.

B: Piggyback ECUs tricking the stock ECU into adding/removing ignition advance and adding/removing fuel injector pulsewidth.

C: Stock ECU reprogramming to require less alteration of A and B

D: A boost controller is a standalone device that has nothing to do with the tuning of the engine... it merely regulates the boost pressure in a turbocharged car.
