Hey i've heard from some people that the 96 JDM ITR Motor is a OBD1 but I also heard that it's a OBD2 so which is it?

 

96 would be OBD2

Actually, it's neither. However, it uses the sensors of an OBDI motor (minus a VTEC presure switch and EVAP purge valve). And the plug and chipset of the ECU is similar to a USDM OBDII ECU. But the ECU operates much like an OBDI ECU. And other than dealing with a different plug style and pinout, converting a car to use a JDM P73 is pretty much the same thing as converting a 1988-1991 car to use a 1992-1995 ECU.

 

so does this mean I still have to get a obd1 to obd2 conversion harness? or can I just use da harness on my 93 cx hatch which is an obd1? Ur help is very much appreciated. Thanx.

 

you can use your obd1 harness on it.

 

The intereface on the P73 ECU will be that of a OBD2A. 96-98 Civic, 96-99 Integra. So if you were to have a OBD1 car receiving the ITR swap, you'll need a harness adapter in order to run the P73 ECU.

 

what harness do you have on your underdash?obd1 or obd2a?

 

i have all obd1 obd2a,i'm rewiring my harness to make it to u.s spec.

these are my toys
96 itr rhd
98 gsr
95 gsr
92 accord ex
99 accord ex

I'm running all obd1 harness, it's a stock 93 hatch. So this mean's I have to get the obd1 to obd2 conversion harness rite?

 

what ECU do you have? Is it USDM or JDM?

 

its a jdm motor wit jdm ecu
