i just bought a d16y8 motor.. i got a 97 civic dx.. i was woundering if i had to get a new ecu and wiring harness to run the y8 and the vtec.. or can i run the vtec to my ecu i got now.. let me know.. my aim is teamsohc or leave it here

 

my aim is teamsohc05

 

im extremely confused on what youre asking, are you looking for a Vtec Controller?

please explain.

thanks

 

you need a P2P ecu and hardwire the vtec to the ECU.

 

ok... if you can im me at teamsohc05.. but i got a 97 civic.. i just got a d16y8 motor for it.. my stock motor is d16y7 its a dx car.. i was asking if i need a diffrent ecu for the vtec or could i run it straight to the ecu and wire it up.? i dont want to run a switch for it

 

this is my 5th message cant reply more.. someone im me and let me know if i need to diff. ecu or can i wire it to my y7 ecu.. im me at aim... teamsohc05

 

you need the d16y8 ecu and you will need to pass a wire from the ecu to the vtec controller yourself

 

so i can just get a y8 ecu and run a wire from the ecu to the vtec controller instead of getting a new wiring harness

 

next time you get the motor try and get the ECU and Motor out of the same car along with the wiring harness makes everything sooo much simpler..

 

yea i don't think he was wanting to use a vtec controller....i think hes asking how to wire the vtec to the dx ecu....or get a y8 ecu

how did vtec controller come up?

 

Use an 96-98 EX wiring harness and ECU.

That'll have everything including the plugs for the VTEC and everything you need to run the Y8 flawlessly without any hackwork.

 

Specifically, you will need to run 4 wires if you do not use an EX harness.

ECU to VTEC solenoid
ECU to VTEC oil pressure switch
VTEC oil pressure switch to ground
ECU to knock sensor

If you do use an EX harness

Then you have to deal with the 4 wires going to your secondary HO2 sensor since these wires are not included in an EX harness. That's because in an EX the 2nd HO2 sensor is underneath the car after the cat as opposed to the DX which has it located after the cat that's integrated into the exhaust manifold.

Either way it's 4 wires.

If your DX is a hatchback then there are additional issues.

 

thanks.. i found a 98 y8 ecu and harness from a friend 150 for both
