1993 Lexus LS 400

Electrical problem
1993 Lexus LS 400 V8 Two Wheel Drive Automatic 188901 miles

will a 1990 ls 400 ecm (computer) work in a 1993 ls 400 is there a difference. I have a 1993 ls 400 sometimes it will accelerate to the fullest and most of the time it wont. I had it scanned it said mass air flow sensor bought one and it didnt fix the problem. Put it in the shop they said it was ecm. If thats the problem will the 1990 fit?
