ECU question

[civic209]

ok so i have been thinking about replacing my ecu because the p1457 code is still popping up after i have replaced canister system and i have noticed a few things. Why is it that some say only 96-97 dx/lx/cx and dont include 98 lx? My current ecu is from a 97 i believe p2e l31. I have a 98 civic lx and when replacing the ecu which one should i look for? p2e337? p2e l31?

some of the ones im looking at
