Looking for the titled ECU. F23A4 ULEV 4-cyl for 02 sedan that's about to be a manual. 2001 is same part number. Part number I found is 37820-PAA-L23. If anyone knows for sure if the year doesn't matter despite Honda showing a different part number or if a ULEV air-fuel/o2 sensor will work in a non-ULEV ECU without throwing codes, let me know as well. Also willing to trade my current auto ECU for it. I have three ECUs now including the one in my car.
