I was wondering when the vtec is supposed to engage on a stock d16z6. I just bought a chipped ecu and I want to have the engagement a little bit lower then stock, so I was wondering when I should have it kick in. Right now I have an automatic ecu so I bought the chipped one and I get to decide when the rev limiter is, the vtec engagement, and the fuel and timing maps. Thanks for any help.

if i were you i would try it right below 5000 like 4800. that way youll always stay in vtec

Stock engagement is between 5200 at partial throttle and around 4800 at full throttle.... also there is no point in moving vtec down if you dont have alot of motor work.. Im guessing you have some boltons, therefore the stock point is where u should set it. Honda set vetc at the point where it would be most benefecial for performance etc.

I agree, honda paid alot of people alot of money to tune their car's. Leave it where it's at unless you have extensive mods and a pro tuner.

I thought stock Vtec was 4800

yea i'm gonna have to go ahead and agree with that... unless you have say... top end internals springs, retainers, valves.... and so on then i would stay at least close to the stock engagement

Nope its higher when not WOT but with having the pedal completely floored its about 4800

Buy yourself some dyno time and let them mess with it. Butt dyno tuning is not only detrementel to your performance but can also lead to serious problems with your motor if run end up with it too rich or too lean.

Correct me if wrong but it seems the later the vtec kicks in the harder it kicks in so naturally the earlier you activate vtec the softer it kicks in..... something to do with the higher up on the revs the more oil pressure and vtec is controlled by oil pressure????? does that sound right? example: my p72 (obd1gsr) ecu kicked in around 5k (give or take a little) ive got a p30 (obd1b16) and it kicks in a 5600 (give or take a little) and i know its not my imagination...... but when the vtec pops (with the p30) it pulls much harder!

no u idiot it just means that your ppower has dropped so much because ur still on the non vtec cam lobes that when it does kick in it feels like your going alot faster even tho a car with stock vtec engagement just ripped your ******* open while u were crusing at 8000 waiting for the cams to cross over!!!

I'm pretty sure stock d16z6 Vtec engaged at 4800rpms. Not like I would know, I just own one.

Your post probably would have been a lot more informing if you left that out! I asked if anyone knew the right answer. This is a forum to find the right answers so that you dont walk around with the wrong ones right? Do you beat your kids?

Full throttle 4800.
Partial throttle 5200 from what I know.

R Thizzel

That is correct sir. I would put it at 5000

tommyboy

5200 rpms, thats my final answer.

who cares i have a d16z6 and u cant feel it kick in anyways no matter what so its pointless...u only feel it with a B series. Friend has a LS/VTEC swap and it screams like no other. Its all about the oil...

Kyles ej1

i thought it was like 5600, maybe thats y my intake is so loud at like 4-5000
