I note that the Z22SE ECU part number(?) 12202143 has some different versions 09391263 (BA), 09391273 (BB), 09391283 (BC).
Can anyone tell me if I can use any of these as alternative to my existing with same part number? With CIM and chip etc etc.
Some versions seem a lot more available than others.
Wonder if a later one (higher number I assume) would be more reliable?
