I am working on a 96 cx with a JDM GSR. Running the obd2 jumper to a JDM P72 computer. I cant get vtec in no way,shape,or form at all!!!! Its pissing me off so bad. Some one help????????
List of thing i have tried:
Replaced oil pump
Replaced vtec solenoid
New pressure switch
Checked and recked the head along w/ the rockers and cam caps just double checking everything
Checked wiring, even tried hard wiring straight to the ECU, this is what makes me think it could be an oil pressure issue
New oil and filter Any help would be greatly appreciated

 

try buying a car with vtec already set up

 

Or something thats not a honda

 

No CELs?

 

Is it warmed up when you try to go into vtec?

 

has the ECU been messed with or is it never been opened. What about the ground for the Pressure switch, is it a good connection. if you think its a oil pressure issue , you could get a pressure kit and screw it in on the front of the head on the passenger side.

 

I'm not new to hondas i mean i've tried everything yeah the car was warm. Honda is what i do! This is a simple bullshit fix that i just need to figure out. I just called rywire so i guess i'll get a harness made. pretty sure its with the wiring

 

The P72 is virgin its never been cracked open at all. No oil light or anything on so i guess its not the oil PSI. as far as the computer says the only MIL is an O2 sensor.

 

JDM P72s don't have a VTEC pressure switch input if I remember... I could be wrong though..

 

maybe its got those special vtec killer toda cams
