i got a 96 f22b1 vtec motor running by a 92 p28 computer and i need to know how to hook vtec up to the computer and which pin to use. the vtec i activated by the horn. but now its turbo so got a ecu from phearable.net. so just need to know if i have to leave it the way it is or can i hook the vtec to the computer since 92 accord dont come with vtec.

 

why would you want to activate vtec by a horn switch?

CD5 vtec systems engage at low rpms. it should be hooked up to the ecu.

 

it was hooked up to the horn switch before the turbo now i am trying to hook it to the ecu but dont know which pin has to be used because 92 accords dont come with vtec. so how do i hook it up to the ecu.

 

Considering that your obviously not using a 92 Accord ECU it doesn't matter that they didn't come with VTEC. You need to hook it up using the OBD1 ECU pin out. It will be easier to find your answer if you search for an OBD1 ECU pin out.

Are you sure that you ordered a VTEC ECU from Pherable? Because it would probably be an OBD1 P06 (w/VTEC added) or a P28. You need to find out what ECU you are using before anyone can really help you. If it is chipped then I highly doubt that it is an OBD1 Accord ECU.

 

i ordered the vtec ecu from pherable.net. i told them it was a 92 computer programed for a 96 motor. i tried to get ahold of the pherable people but they are not very help ful they just keep saying to look at the tech area. would you have any idea what number ecu they would of shipped me p28 or p06

can anybody show me a 92 accord ecu pinout

 

Like you said the 92 Accord didn't come with VTEC. Therefore the ECU pin out for a 92 Accord isn't what you are looking for. You are looking for the pin out for an OBD1 VTEC ECU pinout. If you Google "OBD1 ECU pinout" you will find links similar to this.

But..... If all your looking for is some home cooked spoon feeding. A4 is your VTEC solenoid and D6 is the VTEC pressure switch.

 

I'm wiring up the VTEC solenoid and pressure switch in my 92 accord with h22a4 engine right now.
I know I run the one wire from the solenoid to the ecu, but as you stated the pressure switch has 2 wires;
I know I run the colored one to the ecu, but where does that black wire go to? Do I run that to a ground or do I run it to the ecu also?
Please help, I wants VTEC naoww!!

 

You run the black wire to ground.

 

How do you expect to get vtec with just the ecu ? Dont you need the proper internals cuss vtec isnt only from the ecu, isnt it the vtec lobe on the camshafts

 

Yes you need more than just the ECU to have VTEC operate.

The OP has an F22B1 that has all of the proper internals/mechanical VTEC components. He was wondering how to hook up the electronic control components. ie How to wire the VTEC pressure switch and solenoid to his P28 ECU.

Another poster was looking for ground wire information regarding the VTEC pressure switch. He also had an H22A with all of the proper VTEC internals in place.

 

wiring vtec is easy its just 2 wires from your vtec solonoid to the ecu, but i need those damn diagrams too and honda tech isnt the help like it used to be. people are mainly here for the pictures it seems now

 

What ECU & engine are you using? also are they OBD1 or OBD2?

 

p61 ecu. b17a1 and chassis, engine and ecu all obd1

Sorry boss, I only have diagrams & manuals for Accords, Preludes and a few Civics.

Hopefully some one in the Integra community will be able to help you out.

Good luck

 

Thanks for the effort haha i found all but the vacuum, took awhile but ill get it

 

i need the wire colors and location and pinout for a f22b1 with the poa ecu thanks

 

What P0A - OBD1 or 2?

 

This F22B1 CB7 swap is located in the FAQ. Go down to where he starts talking about the VTEC & ECU wring

https://honda-tech.com/zerothread?id=529272&page=1

 

its obd1

 

and my problem is i have to get a connecter off my f22b1 harness and i dont know which one or ones to ground and which one or ones go to ecu thanks for you help

 

VTEC Solenoid
GRN/YEL wire goes to ECU Pin A4

VTEC Pressure Switch
BLU/BLK wire goes to ECU Pin D6
BRN/BLK wire goes to ground (G114 Left rear of engine)

 

is there any way you could post a pic cause im going have have to use differnt connecters and just want to make sure its right trying to get it done tonight

 

and do i have to switch pins a6 and a11

 

Sorry I don't personally have any pics of the wiring & my car doesn't have any wiring left in it right now.




actually there really isn't anything left in it!

 

maybe a diagram or somthing anything to help me out got it running great just want vtec now
