just finished a swap and tracking down the last lil bugs i noticed that under the ecu reference they show pr3-joo being in a 92 teg (jdm) and i noticed that my ecu says pr3-joo. my car runs fine except the low end bogging from either my tps or knock sensor that i havent fixed yet. just wondering if there is any diff in the two or will either work?

There are 2 OBD's available for the PR3.

OBD1 and OBD0

88-91 is OBD0

92-95 is OBD1

You can tell by looking at the plug ends of the ecu.

88-91 had 2 distinctly different style plugs

92-95 had 1 long gray plug, 2 rows tall. (3 rows would be OBD2 or 2b, but the PR3 did not exist in this version)
