I'm converting from an ODB0 PR3 to an ODB1. I want to run a Hondata stage 4b. Which ODB1 ECU should I get for my B16a/CRX hybrid?

 

since you're going to tune your maps you can use P28, P30, P61, P08, p91 ECUs.

most popular being P28 and USDM P30

 

Either of those would be best

you would also need to change your distributor..and add a 4 wire heated o2 sensor and of course the obd1 ecu plugs.. good luck.. hondata can be installed on the pr3 ecu why dont you just stick with your pr3 ecu??

 

Basically, to remove the need to run 2 O2 sensors.
