LM-2 Start-up procedure question
When reading the manual it seems to contradict itself.
When you power up the unit it automatically warms up the sensor.
It states the sensor must be connected and on when the engine is running. Then it says not to start the engine with a warm sensor.
So what is the right way to do it? If those statements are true the only way I can think of is to start the engine and LM-2 seperately, then install the o2 sensor in the exhaust which seems weird

I think it's intended to be used on a switched 12V power supply. It must have power to it while the engine is running, but you don't want it pre-heated prior to starting the engine. I attach mine directly to the battery, so I made myself a quick connect harness so I can plug it in just before starting the engine.

Ok thanks mj, that makes sense to me now. I guess shutting down is the same too?

No problem dude. I think the reason for not wanting it preheated is to avoid damaging the sensor if there is condensation in the exhaust.

I've done all kinds of things to the sensor and not had an issue.
Of course, now one will fail having said that. The sensor I have in now was in all Summer and prior to that as well.
