Obd2 h22 swap questions

[thepowderblue]

Oh dang I am getting a H22

My question is the h22 is a obd2 and It comes with the dizzy and ecu and uncut harness and injectors and all that good obd2 shit but what is required to convert my cb to obd2? Will the ecu plug right in and how do I get the ecu diagnostic plug and all that stuff.

How do you not know about this topic being covered MANY times before this? You're not even new here. But since you don't feel like searching and want the answers spoon-fed, I'll give them to you.

You want an OBD-1 H22/H23 upper plenum and TB
OBD-1 distributor for a DOHC engine matching your current coil configuration
OBD-1 H22A injectors
P13 ECU
You'll need to add wires for IABs, a knock sensor and VTEC.

Sell the other stuff.

Search in the future and stop being lazy.

Jarrett, He's asking how to convert his CB to OBD2 not the H22 OBD1. OBD2 cars are easier to diagnose problems on.

To the OP, I think it would be a PITA. I would think you would have to add more sensors to some things on the chassis but I really don't know.

If I turn the h22 into obd1 what does he mean I need an OBD-1 H22/H23 upper plenum and TB? I am running a h23 obd2 tb and all the sensors on my f22, well all minus the map. I lift it in its black box. . what makes it obd 1 or abd2?

It means you need the things Jarrrett listed.

rewiring your entire car for OBD2 would be very difficult, and I'm pretty sure you wouldn't be able to use your stock cluster without serious rewiring.
