Review on 📊 PLX Devices DM-6 SM-AFR Gen4 Gauge Combo: Advanced UEGO AFR Air/fuel Ratio Monitor with Bosch LSU 4.9 Wideband Oxygen Sensor Controller and 2 1/16" (52mm) OLED Touch Screen by Jimmy Franklin

Bought to tune the carburetors on my bike. Works great and has the added benefit of a voltmeter. I'm going to buy some extra boxes to be able to see oil pressure and water temp. The installation is quite easy. The instructions are well thought out. Sensor status is a good feature. I noticed that many people say that the sensors don't work for a long time. I have a theory on this, if the engine you're attaching this to is running rich, it could cause a sensor failure. The same goes for the oxygen sensors that come installed on your car from the factory. Leaded fuel will also shorten the life of the sensor. So if you plan on using it as a tuning aid, a second sensor might be needed after you get it right in the long run.
