I have a 1991 CRX si with a B16a. I have a PW0 ECU, not chiped. Everything was good till 2 days ago, I was driving then I gave it gas hit 5000 But vtec didn't work, so I keept giving it gas then it redlined at around 7200 rpm, when it should be redlining at 8300. so now I don't have Vtec & redlines at 7200. Now when I drive the car it feels like a LS motor.

Can any1 help me?

Ps I did try on searching & didn't find any threads on this.

Thanks
