I am new to s300 and cannot tell if my vtec is working? I get a spool error if its not disabled could it be the pressure switch?
Thanks

According to the datalog, the ECU is sending a signal to activate VTEC. Beyond that I cannot tell anything from the datalog.

Hmm thanks for looking. I have right dizzy on now, drove and its still not cracking. Can't I hook up a test light to a wire that goes to the ECU C15 I think??

Try the ECU in a known working vehicle.

it shows that your vtec pressure is not on...
