P28 S300, hooking up wideband.

So was reading online and figured I would post up to see if anyone locally has done theirs like I am planning.

Reference material I read:

P28 S300, going to wire in my AFX wideband to output wideband readings to the ecu for logging and whatnot. So plan is, AFX wideband output wire to D10 (ELD) for input and then cut resistors at locations R136 / R138.

Then something about configuring the software if I need a voltage scale correction, which I have to look and see if I can following along once in the smanager since I am not familar with the screens they are talking about, to read the 0-5v input from it.

Is this how anyone here did it. No problems?

Its been a while, but all I remember doing is running that one wire to the stock o2 wire in the ecu harness. I simply cut it near the ecu plug, left the old wire dangling, then soldered the wideband wire to the o2 wire I just cut from the ecu harness. In the s300, you'll have to tell it that you used that output instead of the eld. Hope that helped.

yea i did it.. i run one o2 sensor (the wideband). im also running closed loop. so therefor instead of putting another o2 sensor in the exhaust im using the narrowband output from the plx to run to the ecu for the closed loop duties. then i run the 0-5v output to the ecu for datalogging afr's. its really simple, im not sure what your exact quastion is.

Just if people were using the ELD D10 pin for input and cutting the 2 resistors R136 and R138?

Seems thats the suggested way of doing it but opinions vary, yes very simple to do I am not asking that. To clarify I was bored more than anything and figured I would ask if thats how people locally ran theirs without problems.

i dont remember which input i used specifically for the wideband as i am using all the inputs for other things such as dataloggin switch, full throttle shift, etc....it doesnt matter which input you use.

Cool, thanks for the input guys.
