[Supras] Auto Trans & Oxygen Sensor Questions

[Christian, Skip]

Sean,

	Sounds like the LC-1 O2 sensor is higher quality than stock.
	What different in the "wideband" output of the sensor ?  I just
assumed that the output voltages would be the same for narrow or wide
band.  Are they different ?  Also, I keep hearing of "analog" output.
Is there a "digital" output on a wide band sensor ?  I'm just trying to
understand why the wide band output will not work with the factory ECM.
	Where's the best (cheapest) place to get an LC-1 ?  Approx how
much does one cost.  My car has about 220K miles and the original O2
sensor has never been replaced....

Thanks, Skip

Using an LC-1 controlled wideband sensor makes a VERY noticeable
improvement. in addition to giving a wideband output for tuning, it
provides a much cleaner narrowband signal to the stock ECU. My old 87
n/a went from an ALMOST glass idle at 750-800 to a dead smooth idle as
low as 450-500. the software that connects to the LC-1 provides for you
to use a laptop as an O2 sensor gauge and datalog so you do not have to
buy any more expensive tools for the job.

do NOT connect the wideband output to the stock ECU, use the narrowband
output for that.
