The A9L was the best stock ECU because of the fuel curves and stuff. I dont know about the worst computer though. If you are looking into buying a new one, it may be cheaper, and better to have yours re-mapped.

Actually the a3m1 was considered the best option for upgrading back in the day along with the a9l being a close 2nd. Before tuning was around the only way to change any timing maps or fuel curves was by changing the pcm to either of these. Nowadays with chip tuning ...flashing etc... theres no need to change out the computer as a tuner can control all these tables.
