FWIW, the actual readout does go down to 10:1, but the LED sweep only shows 11.
That being said I own one and its not very accurate. Matched against the NGK Powerdex AFX (with NTK sensor) the AEM unit will show similar readings only 50% of the time. Rest of the time it will be as much as 2 full points out!!
