ive noticed that my VTEC crosses at a different rpm when i go threw the gears. it ranges anywhere from 4200 to 5300 going from first threw fourth gear. any suggestions on what i should look for or is this a common variable for the engine

 

depends on what motor and what ecu.

 

B18C1 transitions over to vtec between 4,400 RPM (or is it 4,200 RPM, my memory is failing right now) and 5,000 RPM, depending on throttle position (and possibly load, wish I knew for sure on that one though).

So, its normal.

How are you identifying the transition though? Most people can't hear or feel the transition, just the secondaries opening later.

 

im running a stock GS-R with stock ecu

 

LOL the car has an unruley loud fart can on it. came with the car not my preference im an RSR fan personally because it doesnt have to be loud to go fast

 

RS*R Invidia is what I'm running. Love it.

 

I can audibly hear my vtec crossover on my gsr but i have a skunk2 cams and several other bolt ons. Mine hits around 4500, but my Mugen Cluster seems to read a little bit off. the IABs hit right at 6,000.

 

mine is liek urs too
im guessing it is normal
but now i have a chipped p28 ecu
n i made vtech to come in at 5,000rpm
so everytime at 5,000rpm it kicks right in

 

what ecu are you running?

 

the OP said a stock P72

 

check your oil level mabey
