Review on Auto Meter 4379 Ultra-Lite Wide Band Air Fuel Ratio Kit: Accurate Monitoring at 2.3125 Inches by Antonio Baker

High latency, only 1Hz updates. The countdown at the start is annoying. Instead of starting immediately, it counts down from 15 to zero within that number of seconds. On a cold start this isn't a problem - the O2 sensor needs to come up to operating temperature anyway for it to work - but on a warm start, for example after you've slipped off the outside of the track, parked the car and then reassembled it - unnecessary and thoughtless. The instructions are useless. Half of the wires on the harness aren't needed, which the instructions don't tell at all. Greddy Profec's instructions in Japanese, which I don't read, were clearer.
