ok so I'm swappong a b18b into my rex and I need to get a new ecu for it. I have absolutely no knowledge about ecu's. I need to know where I can get one.

 

Ummmm..... the classifieds, ebay, local swap shop?

Here's a list of all your possible ECU choices depending on the year and OBD of your engine: http://www.hondata.com/engines.html

 

well first u need to know if your wiring is odb1 or 2 then decide which ecu u want i have a b18b with a gsr head and i converted it odb1 and put a chipped p06 ecu in it so u can go with that, u can get ecu's on ebay.

 

oh hell ya that's exactly what I needed thanks man

 

i did the same thing. i had a 96 ls obd2 motor. converted my engien wire harness for the obd2 motor, then i bought a p75 and converted to obd1
