d15b7 in a 89 hatch. it has obd1 injectors but obd0 ecu. do i need one? are the obd1 injectors gonna work on a obd0 ecu?

 

The injectors will work fine, bypass the resistor box. The OBD1 and OBD2 injectors are high impedance, so you don't need the box. You can always put the OBD0 injectors in if you want to keep the wiring stock. Assuming it's an Si of course...

 

no its a dx. so to bypass the resistor box i just wire the injectors straight to the ecu? what would happen if the obd1 injectors were ran on an injector box?

 

they wouldn't work

 

but would they get messed up or is it if you hook up obd0 injectors without the resistor it burns them?

 

... your injectors are "wired to your ecu"

The injector resistor box makes a 12v+ circuit into a 5.5v+ circuit (resistance)
This is not necessary for OBD1 or OBD2 injectors.
The injector resistor box has 1 wire from the 12v+ Main Relay which switches on when your ignition is in the "on" position. The other 4 wires go to your injectors, the injectors don't fire until the ECU grounds that circuit.
Bypassing the injector resistor box means that you connect that 12v+ Main Relay wire, to all 4 of those wires without a resistor inbetween. Thus giving 12v+ rather than 5.5v+ to your injectors.

I personally think that the OBD0 ECU is specifically designed to carry 5.5v+ NOT 12v+ through its circuits in the ECU, but i've never heard of an ECU going bad because of a 12v+ injector circuit. So i won't stress it until i find out for sure.

 

yea i got it all figured out thanks though
