ok im going to be doing a swap..into a 90 hb dx,the is a jdm d15b..thats coming out of a 93 hb dx...would it be easy to keep it obd-0.if so would i need to rewire some things to make it work right in the 90dx..or should i make it obd-1..whatever one is easyer to do will make it easyer on me..ive done swaps before for but not putting a newer motor into older cars ..i have to learn sometimes

 

you need to ask yourself do you really need obd1? what ecu do you plan on using if you don't go obd1? also, you need to look at would it be cheaper just to buy the conversion harness, or is it going to be cheaper to run pre obd electronics?

 

nope dont really need obd-1 it just cross my mine..also im going to be using a p28 ecu with i know i will need a obd-0 to obd-1 harness..but what needs to be done in order to make it work
