My vtec i was told was suppose to engage at 5500 rpm. I have a 92 civic eg with a 2000 si motor swapped into it. so why does it engage around 4700? about to go to the track this weekend and just wanted to make sure everything was ok.

 

What ECU are you running?

 

and who basemapped it? idk of any vtec that engages that early. even the gsr first engangement.

if your supposed to be 5500 is stock its supposed to be 5800.

 

vtec only engages once on a gsr.. the manifold flaps open at a diff point to give more power

 

type r ecu. it has a crome tune so idk who did it really cause i didnt install it. its got a 3k 2step and redlines at 7k which is annoying.

 

For your setup you had your ecu chipped so whoever did it chipped it at 4700 rpm. It's no big deal if your going to the track or if you don't mind it kicking in that low

 

If its redlining at 7k your not getting full power out your car get it checked
