Hello to everyone Im new to this site, It seems really Informative so far.
My questions are:

I just put a JDM D15B Vtec in my 90 CRX Si (Built by Exospeed), I just bought the OBD0 to OBD1 jumper harness and a P28 ECU and the Dizzy.

What all does it intangle to do the OBD1 swap, Ive installed the Jumper and ECU ,
Does anyone have a diagram showing the repining of the Dizzy, Ive added the 3 wires for the Vtec and the other wire for the O2 sensor.

also I heard you have the change injectors or modify the resistor box some how?

I really need help with info,

Thanks, Bryan

The resistor box needs to be eliminated. If you look at a saturated injector style diagram versus the peak and hold diagrams you will see the difference. As far as the distributor goes, the sensors are identical so I am not really following what your asking. Just as long as your clear you need an OBD 1 distributor to work with the OBD1 ecu, then just simply use an OBD 1 style plug and solder it up. Don't forget about your VSS signal either.
