Ok im seeing more and more of them lately....i know that with a v-tec controller you can control the points when the v-tec switches over...but who can tell me more about this. Are they any bad results on the engine and what are the best (or only) brands for this product. Im also just a little confused how this product would be good unless you have internal mods.

 

do a search first. this topic has been covered many many times and will answer alot of your questions.

 

I have the Jackson Racing version. What i didn't know when i bought it was that you can not engage vtec any lower then about 3900-4000. So i got screwed there cause i didn't understand it. So then i got the thing hooked up and was running it at about 3900 rpm and i was told by a respectable person that i wasn't getting any power down there. So then i was like WTF was the point of buying this thing if the stock engagement is at 4400??? so now i just got it at about 4100. If i were you save your 350 bucks and buy something else. I know i would if i could. And if someone could let me know if i really am losing power by having vtec engage at 3900 it'd be nice to here it from more then one person just to be positive that thats true.

 

well there has got to be some reason that in vtec cars they have two small rocker arms (or whatever controls that) and two big ones for creating all-around power, and mainly still getting power in the high end. otherwise they'd just have the big arms, right? i dont know much, but i was just thinking about that....

 

ok now i'm glad i got the vtec controller. Because now i'm getting a Skunk2 intake manifold which by doing this now gets rid of the butterflys that engage at 4400 from the stock manifold so i would just have vtec engaging at 6000rpm. Well since i have a vtec controller i can turn vtec to engage whenever i want. So i can have it engage at the point where the butterflys engaged. Ok i'm happy now. Oh and by getting rid of the butterflys i will have a deeper exhaust tone so i'm told. Which i'm glad . Just letting you know that there is a good reason for it. But if you don't plan on getting a new intake manifold then i wouldnt waste ur money on getting a vtec controller. Just my opinion though.

 

no...you shouldnt plan on getting a vtec controller if you dont plan on getting cams. they are more important than the intake manifold.

 

Type R cams are in the near future. Those or the Skunk2's. Can you gimme any info on them or neone??

 

Vtec-Controller by itself isn't worth the $$$...get the Apexi-VAFC (controls vtec engagement and fuel-curve). You won't be able to use any of these devices effectively until you spend some time and $$$ on some dyno tuning, and obviously you won't be able to tell if you've made any concrete power gains unless you mess with the settings on a dyno.

Type-R cams are supposed to be the best for pure street driving; although I know Skunk Stage 2's, JUN, and some of the less aggressive crower cams are also very streetable. I personally was considering a CTR intake cam + ITR exhaust cam but judging from some of the dynoplots I've seen I don't think it's aggressive enough (unless I plan to do forced induction later on). Regardless, I'm keeping my engine stock for now until I get more experience in auto-x/track.

Vtec kick in at 5800 rms stock on Gsr not 4400. Vtec also kick at 6000 for S2k and 5200 for 5th gen preludes

 

Anyone know for sure about this? I too always thought it was 4400 for the GSR and a higher, 5800 for the Type R. (?) Just curious, what about the Civic Si?
