i have a 91 civic si that i want to convert to obd-1, i know i need the jumper harness,
but what do i do about the injectors, i have rc310cc injectors and am running 9psi on a d16z6, how do i do away with the injector resistor box? also my ecu is set up with 4000 rpm drag hold, do i need to put my speed sensor on the tranny so the car will rev past 4000 or will it just eliminate it? if i did that i would have to run an electronic speedometer, and what are all the extra wires on the jumper harness that have to be wired up? i assume some are for the 02 sensor and some for the vtec and speed sensor, anything else? any info would be helpful

 

i read a previous post in this but didnt really help on the couple questions i had

 

how do i do away with the injector resistor box?

why? just leave it, damn near all large injectors require the resistor box...

also my ecu is set up with 4000 rpm drag hold, do i need to put my speed sensor on the tranny so the car will rev past 4000 or will it just eliminate it?

if your car has a working speedo it shouldnt be a problem, the VSS is in the cluster...

if i did that i would have to run an electronic speedometer, and what are all the extra wires on the jumper harness that have to be wired up?

no need for that ----...read above reply...

i assume some are for the 02 sensor and some for the vtec and speed sensor, anything else?

yeah the 'extra' wires are for VTEC, VTEC pressure switch, Knock sensor, O2 sensor heater...i think thats it...

 

thanks,
but the only problem with the speedometer thing is my obd0 si requires a cable speedometer and the obd1 is electronic, loose the cable or the sensor?

 

leave yur speedo the way it is, u dont have to change anything with the speedo
