obd1 harness
 

was wondering when you convert to obd1 on a hf crx do you have to use a p30?

im using a chipped p28 and when i hook it up my fuel pump doesnt prime

i get this funny hummin sound from the iacv


im thinkin the way the rywire kit is sold its for use with a p30

Re: obd1 harness
 

doesnt make a difference sir


p30 only has a knock sensor which when you have a p28 doesnt mean a dman thing


Does the p28 work in anyone elses car is the real question

Re: obd1 harness
 

yeah we tested it today
runs and drives fine


I need a really accurate pinout for this so i can trace it myself

i bought one of those cheap ebay ones but it did the same thing....thats why i got the one from rywire

iunno what it is ....if i take the obd0 harness and hook the ecu the pump primes and all....

checkd all wires on obd0 side and theyre all hooked

Re: obd1 harness
 

does the fuel pump prime with a different computer? maybe a loose connection in your harness, idk

Re: obd1 harness
 

yeah it primes with my pw0

but as soon as i hook the harness up and connect the p28 my iacv humms and my main relay is clickin..vibratin and ---- unno and this is hooking either the one from ebay and rywires


iunno wtf is going on im sittn here going over every wire


no breaks loose......nothin
