You can program an X-Gauge on the ScanGaugeII to show in/out of lean burn. Problem is, the math they use to calculate MPG isn't very accurate on lean-burn cars. Even so, you WILL be able to watch lean burn, throttle position, ignition timing, engine load, coolant temp...although the instant MPG may be off, it'll still give a number. Trying to get a wrong number as high as possible is still better than no feedback at all!
