You do not have a B18C1. If it is from Japan and was paired to an auto trans you have a B18C. There were no numbers in JDM engine codes, and no USDM Auto GSRs. (Just a side note)
Have you checked all the sensors? Maybe your Vtec solenoid is bad, or the switch.
Also, you wont have the secondary butterflies operational unless you run a p72 ECU.
