4 some resin my vtec seams 2 ingage twice at around 5500 Rpm the light turns on a lil dim then at around 6200 rpm the light turns really brite.... Is this normal ? I think it's ecu problem

What modifications have you done to the car? And what kind of car, motor, ecu etc...

Study that, learn how too make a sentence, and spell a little.


Like teal said... What are the specs of the car.

D15b p28 ecu bone stock and it has a bad 02
1993 dx

If you have a hard time understanding the above quoted sentence, I think it may be a reading problem. Go bust the noob's balls who type in all caps, they're the worst.

Back to the technical issue... Fix your o2 sensor first before trying to diagnose anything on the car. The o2 sensor tells your ecu how much furl to put in your motor. If that's not working right then a lot of things aren't going to be working right.

lol. Agree.

Hey Teal! Learn how to spell! It's FUEL, not FURL!!!

Correct me if I'm wrong, but isn't there a D15B with a two stage or three stage VTEC? I know very little about the D-series engines (I tend to stick with B-series).

yes there is, but the 1st vtec engagement is @ much lower rpm than single stage vtec engagment.
and, unless the (OBD2) ecu is happy, there is NO vtec engagement

No disrespect to you Teal but i agree with Josh, you have to at least try and make sense when you are typing in a forum. I bet he would get a lot more attention and advice to his problem if he didnt spell like a first grader, just saying bro put on the spell check its way less of a headache for us to read.

It's the jdm d15b that has the 3-stage vtec, i believe.

To the OP, what light are you talking about, do you have one of your dash lights that engages when vtec kicks?

yeah but even with the jdm d15b thats 2 high...like d-mon said the vtec engages low....around 3k and then again around 5500
