No cross over vtec

[Ep3r_]

My friend has an ep3r and he added in a high flow cat, can feel more power but no VTEC CROSS OVER? Is any1 happening like this?

[cbauto]

I miss VTEC CROSS OVER

[charliebrown]

check if it fell off. it happens sometimes

[integraR]

Looks like missing engine oil?

yea should got more oils

[EKVTIR-T]

was it only the cat got changed?

[Ep3r_]

no trolling please serious question and yeh he has fujisubo catback exhaust and he jst changed to high flow cat

[androo]

Sensor not fitted properly causing the car to go into limp mode? Doesn't explain the 'extra power' though?

[viett]

try resetting the ecu

[lilthug]

more flow

more mid range

less kick


assuming everything is working

if srs - are you trying to hit vtec when engine is cold?

from what others have said - check that the O2 sensor has been refitted and plugged in / oil levels etc etc

Are you getting a cell light/code?

i think its just the mid range feels

it wont feel as strong

plus check oil levels, this can effect it

Normally if VTEC is not engaging on a factory tune (car has original ECU, no Hondata etc) it will be an issue with the VTEC solenoid. With age it can build up electrical resistance and seize to function. Also if the oil is dirty/sludgy it can clog the oil screen in the solenoid.

Or maybe you just aren't noticing the crossover sound now with the loud exhaust. The crossover sound comes from the intake mostly, which is why it is more audible with a quiet exhaust.

Does the car continue to build power until close to the redline? Or does it drop off early?

[EKVTIR-T]

Maybe an intake pipe extension would help

Seriously though, if you're on temp and have oil pressure, and the solenoid is working fine etc, chances are you've increased your mid-range torque and don't feel the 'kick' so much because you have a smooth powerband and don't feel the 'kick' of power coming in gradually.

And that is a good thing!
