[Supras] FW: Auto Trans & Oxygen Sensor Questions

[Sean Cavanaugh]

$150 gets you the controller and a sensor. all you have to do is wire it up and connect the narrowband output to the stock o2 sensor wire. there may be some fidgeting with the heater circuit if you have a 3 pin sensor to avoid a check engine light (putting a 3 ohm at 12vDC resistor to loop the circuit). Sensor gets plugged into stock sensor location for most installs. if you have abnormally hot exhaust (NOTE: rx-7's fall in this category), get the heat-sink bung extender or you WILL kill off the sensor after a very short while (friends rx-7 killed a brand new $80 sensor off in 2 weeks)

basic use, use a laptop as your gauge for tuning and dataloging, or buy a gauge from them and relay the 2nd output (wideband by default) into the gauge. or convert the output to a narrowband signal and use a narrowband gauge.

if you ever upgrade to an aftermarket ECU that can handle a wideband signal, BOTH outputs are programmable as to how you want them expressed so all you have to do is change your narrowband output to use wideband instead. no having to split off the signal between ECU and dash gauge.
