I cant hit my vtec. oil is good changed solinoid and pressure switch
ls/vtec on boost and it loses all power past 6500 rpm i also checked every ground any ideas???

 

do u have a vtec controller?what ecu?

 

yes i do have a v-tec controller and its a chipped p-28 but i tried my stock one also and nothing

 

what head are you running?what did you set your rpm at for vtc to pop?do u have stock cams?

 

I have a itr head and cams its wierd it just started happening and i have had this motor for 6 mnths now

 

when you have stock cams you are not suppose to mess with the vtec engagement.screwin with it will cause you to lose power and your car will run like crap,or vtec wont even hit.set the vtec contoller to the original rpm it is suppose to pop and see what happens.

 

but now why would it work for 6 mnths and now nothing

 

did you mess with the engagement?what rpm did u set it to engage?

 

all motor i had it at 4800 but for the past six mnths its been at 6400

 

just set it to stock engagement..i think 5500 rpm,see what happens.

 

have tried it and nothing
i seriously have tried everything i can think of even totally disconected the v-afc and still notta

 

the only thing i can think of is when you got a new selonoid..did you connect the wires correctly and did any wires fall out accidentally?

 

only one wire on it and no codes i have no idea anymore now if i am correct v-tec is controlled by oil temp and speed correct???

 

yea..speed sensor fucked up?

 

still reads mph just fine and the controller says vtec is kickin in but its not

 

my car was reading mph but vtec wasnt working,got a different speed sensor and it worked.im stumped if its not that,good luck

 

there are 3 wires arent there...black,red,blue...

 

did you have a speed sensor code????

 

i dont know,check engine lights been on since i got the swap due to the o2 sensor not connected

 

Might want to check your oil pressure.

 

OK how much oil pressure should my v-tec line have under say 5000 rpms
i am hooking a gauge straight to the feed line

 

i dont know but at about 900rpm my b16 reads 25-28 psi

 

and i changed sensors and that wasnt it either
