Problem with V-tec on a D16Y8
Hello HMT Comunity:
I have a problem with my Vtec System and ECU. I got a 1997 Civic Ex with the stock P2P OBD II ECU but i have the Vtec engaging by the MSD RPM Activator Switch with a 4800 RPM Engagement point. The problem i am having is that sometimes (recently ALOT of times) i get the check engine and the OBD II Scanner shows Vtec system malfunction. I was wondering if anyone here knows how i can Fix this without switching to a Hondata Chrome or Uberdata or a Apexi VAFC or VAFC II basicly by keeping the Vtec opening with the RPM Activator switch since it is brand new and was a head ache doin the relay wireing to change the RPM Switch from negative to positive wich is what its needed to open the Vtec.

Do what the ancient Inca's did stare at this until you come to a sacred understanding.
and take anything MSD off of your honda and go with crome/uberdata.
Msd makes good stuff for old school v8s but all their ignitions and parts do is screw up a honda ignition.

1- i need a OBD I P28 (minimum or p72 , P73) and have the car converted to OBD1 either with a 92-95 harness or a harness converter.
2- No one in Puerto Rico tunes chrome and uberdata so that means i'd have to buy a laptop , rom programer and tune it myself wich between the lap top , rom programer and the other goodies = alot of cash
