on an '84 eta with the tps switch closed in the idle position does the dme use the signal from the o2 sensor? Also does the dme ignore the o2 sensor signal until the sensor itself or the engine has reached a certain temperature?

it does a little of both, the sensor only works when it's warmed up and the ECU runs in closed loop when the engine reaches operating temperature.Comment

Ahh i see thank you. I've read on the forum that at idle the dme doesn't use the o2 sensor signal i.e. it runs open loop when the tps switch is closed in the idle position is this definately true?
