From what I understand from reading ClubRSX and Hondata tuning notes about the K20a/a2/z1/z3, power is made by adjusting the cam angles, not by lowering the vtec crossover point alone. SO, getting a vtec (or i-vtec) controller alone won't do you much good.Originally Posted by dumbwit3k1d
Also, if you have a K20a3, an i-vtec controller definately wont do you any good.
Hondata K-pro is the way to go if you want to adjust the crossover point AND adjust the cam angles to make power. Or Hondata reflash.
