The 75 ECU can actually read the intake air temp sensor in the air flow meter. The 74 meter does not have that. Not sure if there are other changes...

IIRC.. they just separated the leads from the intake air sensor and the afm between 74 and 75 to cure cross signal interference, the brain on the other end was the same.
But I have been known to be wrong.
