I've read the my gauge isn't working posts, and have come to the conclusion they are written by retards who can't follow instructions... I've worked with loads of innovate gear and never had a single fault.

Mine is a permanant install, and has been fine for over 18 months - driven daily. It is wired to come on with ignition. You will reduce the life of the sensor if you run it cold. The LM-1 will never give you a bad reading though, if the sensor drifits it will give you an error message, and you need to replace the sensor. The digital signal processing is what seperated the Innovate from every other wideband controller. The time taken for the sensor to warm up when the car is started will not effect the life - very low pressure exhaust gas at idle, low rpm.
