hey guys, here is my question..

lets say im driving my car right? and i step on it ..

when the car hits 5k rpm and the v-tec kicks in ,it only pulls hard after 6500 rpm

like the front end goes up and everything,but only after 6.5k..

its running good,but hard ,only after 6.5k

is that normal? please let me know what guys think....

im running a p72 ecu
a blox intake manifold
2.5 inch header back w/ mandrel bent (for future turbo)
fuel pressure reg( w/ no gauge) i know i need to get one ...

oh, and sorry for my spelling..

Check the specifics for your motor, it may only make power to that RPM.

 

I wish my car would rev to 65k

 

it redlines at 8200 ,but it only pulls hard after 6500 ..

i dont know the specs because is a b18c5 with a b18c1 head...???

 

get your car tuned cus that ecu isn't designed for your specs

 

thanks

how do i tune a stock ecu?

 

how do i upload pics here??

 

stock ecu
blox manifold

there's your problem

 

what do you mean?

 

the stock ecu is designed to make vtec and the dual stage intake manifold work together. by going to a single runner manifold like the blox vtec comes on too early and you basically have a dip in power and torque untill ~5700. which is exactly what you described.

 

ohhh,so i need to tune my ecu or chip it ?

man i sorry for the stupid questions
but i realy dont know

thanks a lot

 

you need to tune it

Sick

 

thanks man ...

im trying to add some pics of it..

 

ok im gonna ask y do you have a gsr head on a type r???? wtf??

downgrade??

 

thats the way i got it ....

it was a good deal...

dont know y they put in a gsr head..

 

Stock GSR ECU activates Vtec at 4,800. Too early as already stated. You can't tune a "stock" ECU. You need to either chip it or convert to OBD-1 and then tune or get it tuned.
