Re: OBD 1 LS ECU........ (On Point EK!!!!!!!!)
the boards are slightly different but no actual difference in performance
92-3 ECUs are PR4 (just watch out as 90-1 non-obd ecus are also PR4)
94-5 ECUs come in P75 and in some cases P74
if the code: 37820-P75-A51
the 5 in the third set of numbers means that the ecu is auto

Check out this site:

Also: 92-95 ls/gs is P74 or P75. Like eg6ajk said it's the same performance wise. The difference is the way it mounts in behind the dash and carpet (the 92,93 is different from the 94,95). If it's going in an EG is would suggest the P75 from a 94 or 95. The PR4 ended after '91.
