Older cars aren't subject to smog protection and if the module is set to the OEM configuration it will. I only used a tuning module because it's an easy example

Only cars prior to 1974 are not subject to smog check in California.

And part of the smog check is a visual inspection which will fail in the presence of any non-factory emission related equipment (such as engine control modules) even if their behavior is 100% identical to factory.
