dont know much about ecus, so i really need answers to this question...i have obdo-pwo ecu for a b16 that is no good...i am wondering if it is possible to run an ecu from a newer obd1 b16..i think a p28 or p30 not sure...is there anyway to doing this ? ... and also how much would it cost or should i just buy a pr3 ecu....thanks in advance...

First off the easiest way to go obd is with a jumper harness. You will need that, obd1 distributor,obd1 ecu, and maybe injectors.

The p28 although it is a obd1 ecu it is for sohc vtec but it can be chipped to run a b16a.

What pr3 ecu are you talking about? non obd or obd1, if you are refering to non obd then 50-100 on ebay.

 

Don't mean to hijack this thread, but Magick where wouild I be able to locate one of them jumper harnesses?

 

Contact bown90hatch he is here on the board and he makes a good harness.

also you can try theese companys they make them

also boomslang makes one but i dont have the link to the site

 

when changing distributors is the obd1 legs going to fit or do i need to chop one off. hmm...seems like its cheaper to just buy an obd0 pr3 ecu...

I have a 93 GSR obd1 distributor on a 1st gen B16A, it fits perfect. Not sure about newer distributors fitting on the 1st gen engines.

 

wait..... are all PR3 ecu's obd0???? cuz i was looking at a 92-93 integra motor, trans combo. and it was a PR3 ecu.... i thought they never made obd0 after 91??? can someone clear this up.. don't mean to jump in.

There is also an OBD-1 PR3 ECU, along with the OBD-0 PR3.

 

ok, can that PR3 OBD1 ecu be made to work on a B16A DX with a motor swap?????
sorry forgot to add the car is a 1990

I have a obd1 pr3 in my 89 CRX. It can be programed to run any b series engine.

 

cool thanks??? how much of a pain in the *** was it to switch your car to a OBD1.... sorry for butting in again.. this will be my last reply.

Well, lets see, the harness is plug and play between the obd1 ecu and the under dash harness, plus about 6 or 7 wires that come off the pig tail that are need for the 4 wire o2 sensor, knock sensor, ground, and vtec solinoid. Its not hard at all!

The injectors are also easy, giving you the choice to remain using a resistor box and non obd injectors, or removing the resistor, solding the injectors wires together and using obd1 models.
