mt_goat: not quite that, but pretty much the same functionality. A few of us later year 3rd gen owners still have two 02 sensors (fed. emissions) on our trucks, not one 02 sensor and one AFR sensor (Cali spec.). URD made a 02 sensor calibrator for early year 3rd gens, but when installed on the later year runners it didn't work right (This calibrator was removed from their site about two weeks ago, it was called the ESC1) The product that I am now running works on all the 3rd gen 4runners equipped with two 02 sensors.

Edit: Dale, I noticed that you have a 93. Are you sure you have an AFR sensor? Maybe running the AFR calibrator on an 02 sensor is what's causing your open loop issue.
