ive got probably a stupid question. ive got the d16z6 in my car. was told the vtec hits at 4500.. is that right? i really dont feel it. could the sensor be bad?

Stock it should kick at 5300 or 5500 and go until redline. 4500 is low unless it has a chipped ecu. And if you are completely stock no mod's you really won't feel it or hear hit. Put an intake on only and you will hear the change over.

its not very pronounced in sohc motors intakes offer the sound alot better than stock airboxes, but your more apt to feel it on a dohc vtec motor and yes it should kick in around 5200 or so

EDIT : meant vtec not ctec lol

The d16z6 vtec crossover point is 4800 rpm like they said you won't really hear it on a stock setup

keep in mind the the stock tach is far from accurate

a wise man(aka D-mon^) once told me that it kicks in at 4800 at WOT

but 5500 at normal driving

Is there a way you could modify the ecu from 5500-5300 rpm vtec kick into lower rpm?

Yes you have to have your ecu chipped. Or find one that's chipped and make sure its a vtec ecu and unless your good with a soldering iron have it done by a professional and reputable shop

ah so if my car has p28 in it, it needed to be matched or replaced?

I don't know much about the computer and ecu system, lol

Wire in a vetc light and u will c when it pops of it pops
