Alas, this is what I suspected. I don't know enough about O2 sensors and
exactly how the ECM handles the signal.

Perhaps I should just drive it as it is? <weak grin> Better; perhaps I
should wait for a more worthy project. I'd considered that maybe there was a
ridiculously simple way to piddle with my EFI and that I just didn't know
about it.

Oops, did I say "simple" and "EFI" in the same sentence? Sorry.

Thanks guys;
