Well i just finished a MPFI swap on a 89 dx crx.. i put in a jdm d15b vtec in it for a friend and i still have it running obdo (vtec isnt hooked up) but i wired the dizzy to obd1 because the motor came with a obd1 dizzy.. i thought maybe i switched up pin b10 and b12 at the ecu so i switch thos around and it seems like it runs worse now so i put them back to the way it was before..

i know these sensors are all in the dizzy but do u think the dizzy might of tookin a ****?


code-

4- crank angle
8-TDC
9- CYP

 

You can't run the OBD1 dizzy with an OBD0 ECU.

 

y not? ive heard of people doing it before

 

Oh really?
And how many of them ran correctly?

The reluctor ring inside the distributor has a different number of teeth.
If you run the OBD-1 on your OBD-0 ECU then you get the wrong pulses to the ECU... and it will never run right.

 

Exactly...

 

i called rywire and u are right my friend.. thanks.. it runs but just throws thos codes.. and when i mean runs, it barely runs lol

 

wat about running obd1 injectors just spliced in?

 

Are you running a resistor box or no?

 

na.. i took the 5 wires that lead to the resistor box and put them all together

 

Then yes, you can use OBD-1 injectors.

 

you should really just get you a obd0 to obd1 jumper. for the dizzy, and ecu. and bam! problem solved. wire in your vtec. and bam jdm d15b vtec running like a champ.

 

i would if it was my car trust me.. if u saw my cars u would see there crazy clean.. but this is my friends whip and he is on a big budget so hes tryin to cheap it out.. :/

 

half a**ed equals half fast, I just had to fix a harness for a guy that has all of the wires twisted together and heat shrinked, took me six hours to un cluster that charlie foxtrot.
