You can adjust it. DO NOT adjust it while your car is running, or yes, it will f@#! things up. Verify when you are done that your vetec in point is where you want it. I have found that 4,400 rpm is best on a stock/mild lood. If you have tried to adjust your v-tec in point while your car is running it will most likely default to around 3300 rmp jacking your car up and setting a check engine light. I strongly recommend only adjusting your fuel level at higher rpm so you can maintain fuel economy and still get your power. Let me know if you need help figuring out actually what buttons to press to change your a/f ratio.

whatever imo it is crap already cost me one tps sensor and blew my o2 sensor as well as fouled my plugs out when the wiring grounded out --- it does nothing more than fool the map sensor into adding or lowering a/f ratios as rpm increase.....
Hondata is real fuel management tuning

I don't know how you wired yours in, but I have never heard that happening before. I do agree with you in getting hondata though.

if you are rebuilding the motor bottom to top then get hondata...vafc will not do your motor justice. The basic program starts at like $200, look into it

get hondata now, not later.
or my favorite, aem ems.

if you're cheap, get uberdata... it's free and still better than a vafc.
