i was just wondering if anyone knew what the differences are between the two ECU's. the only difference i know of is that the PR3 came from the JDM Integra and the PW0 came from the CRX SiR

 

[DAFeLUNG]

the pw0 needs one o2 sensor, but the pw3 needs two o2 sensors

that is corect the pwo does use a single o2 sensor witch u can bennifit from but there are less after market programs for the pw0 but they are out there a friend of mine is testing out some chips right now for his pw0. fuel cutoff is at 8000 rather than 8200 on the pr3.And no one knows really where it came from as far as the car and year
