'88 BMW M3, bone stock appearing inside and out except for wheels/tires, exhaust pipe tips and, of course, the engine compartment. 2001, LS1/6, Camaro T56, 222/226 @ .050, .570/.570, LS6 intake, ported oil pump and heads, 400 + hp, 4.10 ltd. slip diff, '01 M Roadster front & rear suspension/brakes, GC coil-over, adjustable Konis, 2700#, daily driver road rocket. Still thinking of dropping an LS7 in.
Correct! Also if your O2 sensor fail to respond satifactory to the ECM's requirements, it will drop back to Open Loop. It there is no response from the O2 sensor(s), like one is unplugged, it will not go into closed loop.
