[QUOTE="Fred W, post: 1019103, member: 3828"] On the first gen, I believe that he ECU code is pretty primitive. When you disconnect the O2 sensor it doesn't know it (no codes) and the Fuel Injection just stays in open loop mode continuously. It still runs the same base map and goes through the normal warm-up routine, just never goes closed loop. Second gens (and later) may be different since they have O2 sensor heaters, the ECU could expect them to come to temp in XX minutes. But from everything I have heard this isn't the case. IOW I think they are still unaffected by the disconnected O2. I'd welcome some evidence to the contrary. [/QUOTE]
