ECU remapped for my b20

im running very rich with my b20 and i was wondering if anyone can remap my honda prelude 2.3 liter ecu to run on my 2.0 liter for my b20 so i dont run so rich. or if you can point me in the right direction as to what would be a good ecu to use for my set up.

Get a few bolt ons. Cali legal!

Switch it to OBD1 or OBD2 and get it tuned.

Use an easly tunable ECU, p28 for example.
