which ecu is in the 91 integra

 

I don't have a 91, but should be a pr4.

 

i should hope that it is a pr4

 

what exactly is a pr4? is their a chance that some of the 91's might have an obd1

 

obd2 wasnt on integras until 96. so yes you have "obd1" if you have on board diagnostics at all.

edit: PR2 is just the model of your ECU...other integras/civics from other years have other "P" model ECU's

vteg is correct, your ecu is a non-obd pr4. pr2's identify euro zc ecu's.

 

i dont know what a obd1 ECU chip will do for an obd0 ecu, but
i do know what happens when the obd0 chip does in obd1 ecu..
check engine light comes on, and, you cant rev past 3300 rpm. it just bounces there.
90-91 integras are obd0, 92-95 integras are obd1
both are PR4 ecu (90-93) so dont be fooled by the PR4.

*** not so patiently waiting for my 92-93 ECU Chip to come ***
