HomeMade VteC ControlleR
 
I started this project 2 days ago and now I'm done. I ran into some trouble like when I hit Vtec the stupid PCM threw a DTC but I fixed that easily. What a difference it makes having Vtec kick in at 4500rpm. Just wanted to post this subject up and tell everybody why spend 100+ for a field or apexi vafc when you can make your own for less than $10. I agree the Field and Apexi controllers look much better but does the same thing as my homemade one.

FYi, its proven that when vtec is set lower than 5000 you will have less useable HP in that range. We did several dyno setups NA and FI, each time we lowered it, there would be a huge dip in the graph. My vtec is set at 5800, I even had it set at 6000 on my crvtec. The only time it really didnt matter was when we were using it on a SOHC vtec, we had it set at 3000rpms, 4500 rpms and 5500 rpms, and the thing really didnt make to much of a difference.

So be advised.. just because you "hear" it sooner, and you think its actually faster, its probably not.

Since the Vtec on Z6's is so weak anyway, if Vtec was disabled, how much difference would that even make?

OnYx 04-23-2004 09:18 PM

Re:HomeMade VteC ControlleR
 
teh Z6 needs VTEC at the top end to make it strong, i have noticed a huge diffrence in vtec when i dident have it and now that i do have it. and Jeff is right, mine is set at 5500 RPM

Re:HomeMade VteC ControlleR
 
Of course jff is right, if you look at it from an mechanical standpoint.. Vtec is mostly about increased breathing via ur camshafts. Vtec Cams are set for top end, If you choose to activate vtec sooner on the b series engines ur most likely gonna lose alot more then u will gain. There is no need to allow extra air flow and long valve openings at low rpm because there is already sufficient flow without vtec. Now Vtec has kicked in and u cant get the right amount of air you need because of the cam situation.

yes, but he said it was at 5800-6000 on his setup. ya, I redline at 2000-10000 rpm, shift in there.

??? fishing + baiting your hook + being the master at it = masturbating

Ravage70 04-25-2004 12:51 AM

Re:HomeMade VteC ControlleR
 
the real question here is when do we activiate masturbating and i think u answered this with one of ur NFSW posts earlier

dragon 04-25-2004 12:59 AM

Re:HomeMade VteC ControlleR
 
what is does masturbating have to do with the vtec activating or what are we really debating?

Ravage70 04-25-2004 01:02 AM

Re:HomeMade VteC ControlleR
 
bah ur too late for explanations

just engage ur masturbating at 6000 rpm

Re:HomeMade VteC ControlleR
 
a z6 without vtec is wack. slow as hell. trust me haha. now that my car is boosted i can feel when my vtec comes on. mine is set at 5800. yeah i know late. but it feels much better. thats how it is on all of my cousins and friends car to. because thats the best point where all the cars feel really good. but then again. everyone else has a fucken h22 while i have a z6. fucken bastids. im gonna own them all. haha. but really though. 5800 is a good point for it to come on. and anything under 5k is redicilous

i think he should posts some pics of the v-tec controller and do a little write up...i think that would be a good point
