I have been searching for a complete "how to" on this topic. With no success! I know there is one out there but my 3 hour search has failed and I am tired of every company telling me they don't deal with OBD 0 ECU's anymore! So its time to get with the program and update, but I want to know what I am doing. I have a 90 CRX SI w/ b16. If you can just provide a link and I can research some more!!
Thanks!

 

well u need the obd0 to obd1 harness i got it from rywire, u also need and obd1 distributor and the ecu u can use the p28 with hondata or just buy a regular obd1 ecu from a b16, is not that hard man u just have to wire up the 4 wire o2 sensor
oh yeah u need a 4 wire o2 sensor u wont be using the 2 o2 sensors that come iwhta that car

 

i know im forgetting more stuff but ill post them later if i remember

 

Is that it? It seems pretty easy to do? Its just getting everything to work together. Where is a good place on the net to get all of the parts. I live overseas and its hard to find parts for a Honda. Believe it or not!

thats all you need

 

Does anyone have a "how To"? I will even take a couple of wiring diagrams if you got them? From my searching whats the deal with the injectors? It seems that I can use them but what do I ahve to do to make it work?

 

Just remove the resistor box or switch to 92+ injectors.I have a brandnew SVE conversion harness for sale as well if you want one just pm me.It actually comes with a instruction sheet.

 

on mine i didnt have to change the injectors, maybe cuz im usint rc 310cc not sure on htat but yeah man thats basically it,


oh and on the obd0 to obd1 conversion harness it comes with some instructions u just follow them and ull be fien thats what i did with mine

 

Sweet sounds good!! I will look for the distributor and ECU and order the harness. What O2 sensor do you guys have? Is it a wideband or narrowband?

 

I see that I need the ECU harness but do I need the distributor adapters to?

ok first off, don't remove resistor box UNLESS you are putting in obd1 injectors which are not neccessary anyways so unless you are doing a wire tuck and you want as few things under your hood than don't even worry about it. And as for the dizzy you can just run your obd1 and repin the harness.

I mean obd0 dizzy^^^

 

u can buy the adapters they are 25 bucks moreless or if ur good with wires u can use rewire the connectors this is how i did mine, just rewire and thats it took me aobut 1 hour u know i was also messing around with other stuff

hehehehhe

OK so this is all I need to do the conversion:

OBD 0 to OBD 1 ECU harness
The dizzy conversion jumper harness
P28 ECU


What year does the ECU have to be? Does it matter? As long as its a manual ECU and it controls the VTEC!

 

the ecu has to be 92-95 (obd1)

 

p30 ecu
