ive been greatly debating on what exactly i want to do with my car's ECU situation. i have an H22 in my 92 accord. and i havent made up my mind as to what will be the best (performance wise). all i have done are basic bolt ons ( i/h/e) and thats about it. i currently dont have an ecu but i was thinking about geting a either a chipped p28 with everything programmed to run my H22 or i was going to a virgin P28 anf get a VAFC to controll everythign else. but, HOW exactly does a VAFC work. does it take the place of a programmed chip? can i controll my VTEC crossover and redline?? am i able to adjust my fuel maps to gain more HP?? what would be the better choice in the long run: vafc or chipped?????
