Icon2 Non vtec to vtec engine

I have a 1997 Honda civic hatchback dx model the engine died on me this week, so I picked up a used zc 1.6l sohc vtec , the guy said it was out of his 1996 Honda si and that he was runing a obd2a p2p ecu, I'm just wondering if this is the right ecu, and if so would it be possible to go to the wreckers and buy a used ecu out of a 97 or 98 Honda si? And I was also wondering if I could run the car with the original ecu in it for now till I can find a vtec one ?

Default Re: Non vtec to vtec engine

You can run it with your stock ecu but Vtec will never kick in considering it doesn't have the wiring to the solenoid and you don't have a vtec enabled ECU. It might even run like crap who knows? But based on Exp a non vtec motor on a vtec ecu will throw a check engine light for the vtec solenoid and you can't rev pass 5K RPM.
