hey guys thanks for taking a look here at my post... i have a 90 rex si and i also have a b17 to put into it...my intention is to have the car remain obd 0 running a pr3 ecu, dissy, and injectors, as well as my stock engine harness... my only questions are about where the extra wires come from on the stock harness after i plug it all in

If i were you i would reconsider runing OBD1. Doing the conversion is not that hard, and obd1 ecu's are easily programmable for future use as well.
If you want to stay with obd0 you will need to locate a pw0 ecu, and a 1st gen B16 distributor, as well as do some wiring anyway.

i'd agree.

 

glad to trade you my PW0 and obd0 dizzy plus o2 sensors and manifold for the p61, obd1 dizzy and manifold/sensor in your still interested in that route... they're right above though...obd1 may be a better choice.

 

I was just wondering why you guys would go pw0 over pr3?

 

There is really not any perforamnce difference with eith ecu, it dosn't matter which you get if your staying obd0.<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by IO_303 &raquo;</TD></TR><TR><TD CLASS="quote">I was just wondering why you guys would go pw0 over pr3?</TD></TR></TABLE>

Thats what i thought, I wasnt sure if you were jusat picking a DOHC obd0 ecu, or picking pw0 for a reason becides its cheaper

 

i would stick with the obd 0, unless you want cheap mans go fast, then i would use the obd1 p28 ecu and chip, it has minimal sensors, and vtec
