Well I did try and reply last night but seems you people have me on a moderation q.. even though I've not done anything wrong.
however I have taken note to your suggestions and tried a different ecu (p28 on crome) today.... still absolutely no difference to the revvs... but as vtec engagement was lower on this ecu.. vtec change over happened.
Not exactly. I would just take it to a tuner shop and have them look at it. It needs to be diagnosed. Good luck, very sorry I couldn't help out any more.
