i didnt know which forum to post this in so i just posted it in the forum i usually post in me and my friends where talking and one asked me "when you install a hondata chip in say a b18c and move vtec to engage at instead of say 5700rpms to 4000rpms how does vtec hit just as hard if you move it to hit earlyer?" i could not explain it to him and i felt like i didnt know about hondas so could you guys help me out and tell me how this is possible

 

ugh
i guess ill take this one
first, a gsr's vtec turns on at 4400. not 5700.
second hondata is a completley programable ecu
meaning you could set vtec to 1000 if you wanted. but it will make the car run like ***.

vtec will not "hit as hard" if you move it earlier in the rpm band unless you move the fuel curve with it. but honda put vtec where its at for a reason. power matched with economy.
i wouldnt reccomend moving it untill you have major headwork and good cams.

yea i was just suggesting any rpm he just didnt understand how you could move when vtec engages and it would work the same

 

oh ok
it dosent work the same when you move the engagment.

 

thanks

 

VTEC is not a 'thing'; it's a system of 'things, and it "turns on" when you start your car. It works for blue-haired grannies and street racers alike. It doesn't matter how fast or slow you are going, if your car is running, VTEC is in action.

Don't mean to flame, bro. At least you had the courtesy to answer the guys question, but I have a hard time getting past these kinds of statements...
