The D15b7 throttle body just doesnt have the map sensor

- Tue Aug 24, 2010 11:07 pm #210415 ok heres what you should do
swap the throttle postion sensor from the d15b7 to the d15b
might be a littlt tricky but it can be done
take a dremel tool and cut a slit in the topof the stud that hold the tps on then use a flathead and un screw the stud andswap it in to the d15b throttle body

- Wed Aug 25, 2010 3:36 am #210449 Ok lets see.
Well in the meantime I got my throttle body gasket.
I put the d15b7 throttle body on the d15b.
My stock ecu popped for some reason. It died
Connected my p28
And she fired right up :D

I have a check engine light on of course
I still need to wire vtec but right now she drives :D

- Tue Aug 31, 2010 7:42 pm #211479 Im running a p28 on my D15b vtec
Instead of running a p08

Does this mean Vtec activates at 4800 rpm instead of 5500 rpm?

- Wed Sep 01, 2010 12:00 am #211532 vtec does not activate at any certain rpm it depends on speed what oil you are using and what kind of load then engine is under
vtec activates between 4800 and 5500
but the difrence between the po8 and p28 is very small you wont even notice

You are wrong sir. VTEC is set to activate at a certain RPM it's controlled by an electronic solenoid that activates the switch when a certain RPM is reached. Which is why you can control the engagement point with a VAFC, by chipping the ECU, or you can even put it on a switch (don't believe me about the switch check this out.
