To tell you the truth, I haven't gotten around to "using" it much. You can set different gauges to certain screens to give you specific info. Mine reads 52 different parameters from the vehicles computer. My main screen gives me RPM's (redundant due to factory tach.), battery voltage, intake air temp., %load on motor, and miles till empty on gas. You can set trip gauges, all sorts of fuel usage and MPG's, etc. You can also read and clear trouble codes. Ultra-guage.com give a vid and pics of it. It's also about $100 cheaper than the scan-gauge. Sorry I'm not more helpful, John (udy2554)
