The only difference between an LH and a HFM SFI injection system is the mass air flow sensor itself.
The only real difference between a HFM-SFI and and ME-SFI is the ME system has the ignition system integral to the engine control module.
When ME-SFI was introduced, that's when the engine became OBD2 compliant, and that's when the engine control module had to store misfire codes.
