The 1990-1993 Accord ECU's a garbage to chip because of there design. All 1990-1991 (DX,LX,EX,etc.) ECU's are basicly programmed the same the difference is in the 92/93 EX ECU.

It's not just the ECU's program that makes the difference it the engines mods also.

I would look into a different ECU for the Accord if you where getting serious into mods. But if you don't need to mess with engine management yet, don't.
