ECU part numbers and differences

[Gene.loader]

Hi. My ECU is fried and I'm trying to track down another however in NZ they are $4000 from Honda.

I understand there are a few different part numbers, are they all interchangeable? I'm looking at bringing one in from Japan

Thanks
Gene

Please read this thread first (although if you can get a cheap one from Japan don't worry perhaps): http://www.u-ukhbc.co.uk/vbb/showthread.php?4042-New-owner-with-an-ecu-problem&highlight=doctor
