Yea...all of them.

The OBD-2 standard, which all cars sold in the US have had to meet since
1996, demands that if the O2 sensor goes bad, the "limp home" or "open loop"
mode (in other words just what you want) must be good enough to not only run
fine, but it's gotta still pass the smog check (750 PPM In my state).

If your computer has a "closed loop" mode, great, but there is no advantage
to insisting on a computer that CAN'T use an O2 sensor if one's available.

Just put some black electrical tape over the "check engine" light and you're
as good as if you'd spent $2K on an aftermarket ECU!


Is there any really easy way to tell what engines are available with non
O2
sensing ECMs?
