OBD2 car, OBD1 motor, OBD1 p28....question is can i use a OBD2 gsr dizzy or do i need a OBD1??? if so has anyone done the OBD2-OBD1 dizzy conversion before??

[civickiller]

yes you should be able to use your obd2 dizzy

[qtmac_mien]

On OBD1 dizzy, isnt there a Crank position sensor in the dizzy? when i swapped my motor i was told that the CPS doesnt need to beed hooked up...its a JDM motor by the way..people is telling me Yes i need OBD1 and other people is telling me i need OBD2..anyone thats done a JDM OBD1 motor into a OBD2 car, plzzz help me

your cps needs to be hooked up. thats why when you do the mpfi swap on 4th gens with jdm b16 motors you need to add wires for the cps. even the jdm motors came with a cps sensor.

yes you can use a obd2 dizzy with your obd1 p28 ecu.

can you show me a picture of a JDM b16 where the cps sensor is because i have no clue where it is...and do i just plug it in using my stock harness or do i need to run it to my ecu??

[civickiller]

you cant see it in the dist. which is why if any sensor goes bad in the dist you gotta replace the whole dist.

you stock harness will have the wires for it already there, the only difference is that the connectors between obd1 and obd2 are different

[qtmac_mien]

if its in the dizzy, am i suppose to splice the cps and run it to my ecu??

[civickiller]

no you dont need to splice, the wires for hte cps are already on your wirign harness because your stock dist uses a cps sensor

so to recap. the obd2 dizzy has a cps sensor and uses it so therefore you stock wiring harness already has the wires for it because your stock ecu uses the cps.

since your using an obd2 dist and you have an obd2 wiring harness. just plug in the wiring harness to the dist and forget about it and watch it work

someone has been telling me that my OBD2 dizzy doesnt have CPS in the dizzy so i need to switch to OBD1 because a OBD1 dizzy has the CPS in the dizzy itself. i am confused.

[civickiller]

i already told you in 4 posts that you can use it. now if you dont believe me then go buy a obd1 dist and give me your obd2 dist because i need to do a obd0-obd1 conversion on my car and i need a dist. then when i do my conversion, ill send you a pic of my car being obd1 and using hte obd2 dist.

[qtmac_mien]

dude i didnt say i didnt believe you..everyone been tellin me this and that about my dizzy, cps and i cant figure out why my car cant starter after my swap.

check your grounds. one on tranny, one on back of block by thermostat, one on valve cover
