EFIEs , that being what.
ahhh, youtube, how'd I guess that.
that's right up my alley ! Grin !
this works ! , the front oxy is the major fine tuning device. ( for some )
on many early 96 + cars this can work.
(results can very , read more)
the car starts, if the ECU enters closed loop ,the front sensor measures oxygen and thus the AFR ratio is set by this device output.
so his presention is real, and in fact I know it to work, both in theory and in practice.
the newer cars might not let you go too lean with out setting a code
and the newer cars might fail the cat performance monitors, P0421 in one case.
this is LEAN BURN technology.
of course do not get caught it is illegal.
What will happen ?( i run this technology in a foreign country , South America.
I run a car with lean burn at my winter home. gas is $8.00 , there. ouch.
I use a megasquirt custom ECU , far batter way to do this and I can run Ethanol.
bad sides:
1: the cat metals inside will be destroyed, in a few 1000 miles.
2: the above fact may clog it up. varies by car and year. greatly.
3: the above will cause P0421 (lazy cat fail) just wait a while.
4: remove it before smog check ,
5. remove it or you mech will refuse to work on your car (heavy fines for him)
on the early OBD2 cars, 96,97 or so you may not get lazy cat fail.
on 99 and newer, fur sure, because you killed the cat.
this technology is not magic it is used on every Prius , the engine runs in lean burn but has a very expensive , different technolgy CATCON that is immune to over heat.
so the answer is , this device will not do anything any useful for the rear OXY SEN.
the rear sensors is ONLY for monitoring the CAT performance.

wiring on the 02 sensor. which wires are for ecm signal. I have a black, black/white, grey, and white.thanks for the help.
depends on year and if what side of connector and who made sensor.
what year car?
who change it last and what brand but...
those colors sound like Bosch side wires. see photo,as I run 100 % bosch on 3 cars.
yours sounds 4 wire.
so:
on a 95 sidekick
it is on veh. side of conn.
what colors on actual sensor varies great amounts.
vehicle harness side; 1995 eg.
yell/blu= oxy senses output to ecu-------------> you
gray/yell = special ground -----------------> you conn
blk/white = power for heater
Pink = heater enable from ECU

this is for a 97 tracker 16v sohc. black, black/white, grey, and white are from the engine harness side. the 02 sensor has two black and two white. im not sure what brand it is.
