My vtec kicks in at 6000rpm is that normal? I thought it was supposed be around 5500 or 5600, I've even read some kick in at 4800.

 

i thought pr3 were obd0

 

# PR3 : 89-91 JDM B16A EF8/9
# PR3 -J00 or J51 : 92 JDM Integra B16A EF8/9

vtec should be around 5250 rpm?

 

with stock ecu's vtec kicks in at 5800 n higher. chipped ecu's kick in lower (normally or on average 4800). on my stock B17 ecu (p61) vtec kicks in around 5500, its been a while since i used it so i dont remember exactly.
