Vtec activated at 3.5rpms, Can it hurt anything? Cause i have a rpm activated switch for vtec and right now thats the only pill i have for the switch? and i want to know if its safe to run it that low right now

 

I dont think so?! I have my VAFC sometimes set to engage vtec at 3800 on my gsr. The check engine light turns on, but the honda mechanics say it doesnt mean anything bad.

 

Oh koo

 

I've heard that you're not supposed to activate VTEC lower than 4k because it causes some problems with oil starvation or something.

 

Activating VTEC at an rpm below 3500 is not a good idea. 1st off you will actually lose low end power and the oil pressure is not high enough to fully lock the rocker arms into vtec position. if you are using an activation box you can change the setiing on the box from 4cyl to 6 cyl and the vtec will activate at 5000rpms, if you have a 3000 rpm pill then it will activate at 4500rpms on the 6cyl setting

 

Oh hell yeah, My rpm pill is actually 3.4k, so if i put it at 6cyl what will that be at

Never heard of a DOHC ZC with VTEC.

 

Oh you the man!!! I've got the Autometer shift module that came with a crappy 3000 pill and was saving up for the 5000 to 6000 set but I didn't even think of changing the setting to 6 cyl. YOU THE MAN, THANX.

 

i hope our friend here didn't pay a shop for a B16 swap. sounds like they may have pulled the old ZC switcheroo. haha

 

Suppose you can activate VTEC whereever you damn want with a ZC

 

what a bunch of dicks, damn. he sold his hatchback about 2 months ago and bought a 90 CRX HF with a D16Z6.

 

First off im talking about a sohc vtec engine

And second of all i think i can tell the differnce between a zc and a b16a ******** to many people here have turned into *********

 

im a ******** ask around, its true

 

dicks? *********????

atleast I check out his profile hoping he listed a newer combo. Maybe he could change his sig line to reflect the new combo.

If you want help, it helps to list what motor/car your working on.

BTW I'm a *******, get it right!

Yeah you shouldnt have your vtec turn on so soon, you will run out of vtec fluid, and that cost a pretty penny. =x hahha.....^5 *********.

 

gas milage will be suck-o even if it does activate properly at low rpms

 

Well we fixed it today, we got it kicking in at 5000.

 

Honda engineered it to come on at 5400 RPM for a reason. To high and you waste time and hard cam switch over. too low and you dont have oil press and it makes your car bog.

Think of it why wouldnt they just put it lower and have better HP curves

 

Ok, my friend is a certified Honda-Tech at one of the local dealers here, and here's what he told me. Your vtech kicking in that low won't mechanically hurt your engine. It will hurt your low end performance though. The reason they make vtech controllers is mainly for forced induction. Having a lower vtech setting on a turbo or supercharged car will give you more power and a smother power band because the turbo is spooling under vtech.

 

WELL I AM ALSO A HONDA TECH and vtec at too low of an rpm robs the bottom end of oil because there is not enough oil pressure untill above 4000 rpms. the forced induction bit is true. as for the guy that has the 3.4 rpm pill your vtec will activate at 5100rpms. http://www.hookupsimporttek.com

 

Wow my sig isnt updated but does it matter? I asked about vtec kicking in to low it should be the same for any vtec engine that why i didnt say sohc vtec. Im not even gonna argue back anymore

Hey mods could u lock the thread please
