Is there A big Differance in the old VAFC, compared to the new one? I just got my 04, and really diddnt want to change much on it, except lower the Rpm were The V-tec goes on, And maybe higher the redline. I see this as my only Viable option.

I dont doubt this topics been beaten to death, but if someone could just give a sumbed up response, id appreciate it. PLEASE DONT FLAME ME FOR BRINGING UP THE PAST!

 

Let me see if I sumb it up for you.

There are a few minor differences between the VAFC and VAFC II but none that effect your requirements.

Either can lower VTEC goes on point but I'm not sure you'll get the results you want without some extra tuning. Neither will higher the redline.

 

To higher the redline, Id have to get the ECU modified right?

 

Yeah, ECU mod!
