just to add, I have the APEXi TT, am very happy with it. it can be set manually or let it do it automatically, even the auto function has different settings for daily driving, harder driving and track driving. it is extremely small and the silver matches interior pieces of the msp. install was cake. but i have to agree with everybody when i say that they are all good. i know two people with Greddys that shorted out, that wouldnt discourage me from buying it though, i just really liked the features and the size of the APEXi, gives you your Time, your O2 voltage, Battery voltage and Air/ Fuel ratios, keep in mind that these a/f ratios are narrowband but it is in a digital readout which is nicer than the sweep back and worth of conventional a/f gauges
