Folks,

In a week I'll have an 022 ECU I no longer need, because I'm waiting to
receive an 022D with the Australian power chip in it,  so this not an
academic question:

I assume the O22D ECU housing itself and/or circuitry must be different from
an 022 ECU, because to handle the Aussi chip, you can't use the 022.  So I
wonder - is the original 022D chip programmed better than the 022 chip?  And
if it is, can you plug it into an 022 ECU and make a better combined unit?

Thanks,
