ok, heres whats happening .... ive got a 90 dx thats been converted to multipoint and has a d16a6 in it ... which is a fast dying motor right now ...

what i am going to do is put in the JDM D15B, get a ond0 to obd1 conversion harness and run the correct ecu, the p08... this way no ghey activation switches and im running the propper maps...

now from what i thought i could just slap on the crx si dizzy by modifying the legs and call it a day, but what my friend is telling me is that i have to use an obd1 dizzy and custom wire it..... is this true when converting to obd1????

it seems really dumb that i would have to do this, cause isnt that the job of the conversion harness???? to run everything to its right place so i dont have to do this ****?!?!?!?!?!

also it was to my understanding that the need for a resitor box depends on what injectors you are using, now on which ecu u are running .... in example i thought that if i continued to use my obd0 injectors even with the obd1 ecu, i would keep the resistor box in cause the injector is the same... is this wrong???? my friend is telling me that even iff i keep the obd0 injectors i have to ditch the resitor box.. is this true!!!!


thanks for all your help guys, this is the last bit of info a really need to get this swap done!!!

thanks in advance!!!!!!!!!

 

you do need the obd1 distributor, no way around that.
just repin the connector color for color.

if you use the original injectors from the obd0 setup, retain the resisitor pack.
if you use the jdm d15b obd1 injectors, solder all the wires that go into the resistor pack together.

 

ok cool!!! thanks for the straight foward info!!!!

 

and let me get this straight real fast .... if i use the obd1 injectors, i should solder the 4 wires together and run them to the 2 yellow/black wires from the original mpfi conversion right???? and thats all that needs to be done?

Correct.. If I were you I would still setup for the resistor box but just bypass it instead of plugging in the resistor box.. That way if you want to run peak and hold injectors later, 2 seconds and your good to go..

 

nice, .. sounds too easy to be true ....

does anyone know if there are any other diffrences that will have to be changed????

in an obd0 block arent there like 2 sensors in the back of the block that are diffrent than the obd1 blocks???? ......

 

ttt

The thermo switch is on the back of an obd0 block but its on the thermostat housing on the obd1 blocks.. Look at the back of the 2 blocks and youll see what I mean.. Its the sensor on the obd0 block that has 2 individual wires going to it.. But on the obd1 block it has a harness plug that goes to it on the thermostat housing..

 

ok, so i am going to have to rewire this sensor then right????

 

only if you want your cooling fan to automatically switch on when the car is getting hot...
