From my past experiences I would match the same year ECU to the same year motor...I've tried matching a 93 ECU to a my 92 motor and no cigar..I also tried a 94 a long time ago and I found the same problem... The ECU plug wiring connections on the back of the ECU did not match, not even close... It seems each year Toyota made a suttle difference with the ECU and wiring....

My advice is find a 1991 ECU to match your 91 1uz-fe motor... Good luck..

You could always go with a stand alone ECU if you have the extra money to spend and tune the motor to perfection..

89 to late 92 are the same then they changed october 92 and stayed the same till late 94 or there abouts .
You could also use a Celsior ECU and MAF from the same years [ 89 to 92 ]

If you swap complete ecu and loom then no big problems. Check your loom and count the ecu plugs and then buy the correct ECU is the easiest. All my early MAF are the same - I have up to 1996 motors at the moment. Aftermarket make things really easy and can solve a few problems. Cheers
