Wideband oxygen sensor

[Sal Lubrano]

Is there a wideband oxygen sensor being made as a direct replacement for the stock narrow band? I really dont want to install another sensor and controler in the car. Is there one I can put in the stock location and the factory ecm can read it, maybe with a translator?

the lc-1 has two outputs and one output can be configured to simulate a narrowband which the ecm can use, problem is you dont want to install a wideband sensor where the stock o2 sensor was , it should be installed in the downpipe atleast 12inches after the turbo

seeing as how you have a powerlogger you should take advantage of the inputs and start logging wideband , you could also read the wideband AF through the scanmaster

It wont be accurate before the turbo, because back pressure effects the readings, and too much heat will cause error codes also, you must put it in the DP.

Eric @ Turbotweak sells two AEM sensors, one with gauge and one without. I know the one with gauge can simulate a stock narrowband O2, not sure on the one without gauge. Their instructions call for installation 18" after the downpipe. A few, myself included, run the sensor at the end of the downpipe but before the dump. Some say with the dump open that it affects AFR readings but at WOT I don't think so, FWIW. Dyno sessions just use a sniffer a few inches into the tailpipe with accurate readings. As long as you are never closed loop with the sensor at low loads, it won't matter. HTH

Could I purchase a Bosch factory wideband sensor and connect the sensor directly to the powerlogger termination block?

i run closed loop all the time, at that point the ecm doesnt even look at the narrowband. I just use it for reference.

What are you referencing the NB for exactly? It's not accurate at anything outside of 14.7AFR. I believe closed loop is using the O2 sensor so are you running closed loop with the WB using FAST or something? The stock ecm doesn't support closed loop WB feedback unless you are running TT 6.0, or aftermarket ECM like FAST or BS3.

kidglok is on the turbotweak SD speed density ..its in his sig "tt sd "
for " reference" he means its being logged so he can looks at it to see what the o2 says , doing this you can sit back and laugh at all these threads that say "shoot for XXX 02 #" after seeing how varied the true AF can be while the narrowband continues to pump out a signal that looks good

he got to see how a narrowband would run from low 800s that seemed rich to 750s and the AF was constant on the WB
