Oh yeah, what is the benefit to having vtec kick in this high? It was tuned that way when I bought the car.
your vtec shouldnt be set that high unless you have aftermarket cams, in which case I hear that the skunk2 stage 2's like to have vtec around 6k. |

I had ITR cams in there before but then I had to swap b16 cams in for a while, but I am getting ITR cams put back in in a few weeks... |

Vtec contoller isn't bad, like the Apexi VAFC or the fields one, but the thing with those is if u have a bunch enigine work done then it makes a difference and they have there limitations, as for your stock set up your vtec kicks in at about 4500 rpms, but u really don't hear till u have the second runners open up @ 6000k. I have a apexi VAFC that i am going to be installing in a couple weeks along with my cam gears, and gettin it dyno tunned.. (01 GSR comptech ice box, comptech headers, skunk2 cams, skunk2 intake, apexi N1 exhuast.)

its actually engaged at 4400 rpms and the secondary butterflies open @ 5700 rpms
the same engine speed for normal single stage VTEC engagement in the ITR |

I thought i read some where that vtec engagement is at 5500 for a stock gsr, right or wrong?

vtec engages at 4400 and the intake secondaries open at 5700-5800. how many times does this have to be posted in this thread alone? :down: |
