AEM WB vs. Glowshift WB?

Not to hijack, but I just installed my eugo. Installed in rear o2, used the datalogging wire, and wired it to the pin for the rear o2. This is right, correct?

I was going to just use nb simulation. With link v3. I didn't really know another way.

With ECMLink, you can put that wire into any available ECU input, it doesn't have to be the rear. But yes, the 0-5v wire goes to the ECU to be logged and you will then tell Link where the wideband is located at so it can be logged.

Good stuff. Thanks Scott.

Why is it worse, it does the same thing but it's just a simulated voltage.

I've ran mine for over a year and still on the same sensor, it's a DD and the sensor is in the front o2 bung and this is without a heat sink. MANY MANY MANY others have done so as well with no ill effects.

I didn't even install the new sensor that came with my MTXL as my old LC1 sensor is still working great.

Because it's not a true signal, it's an emulated signal. It was to fast for the ECM which caused irratic idle/cruise AFR's. (at least the PLX unit I tested was) Test it yourself, monitor the output form a NB sensor and then monitor the emulated NB out on thr WB02. The NB simulation gave me major problems on my 86 grand national ECM. The DSM ECU's aren't much faster.

I'm not saying everyone will have the same results as I did. I'm just telling you what didn't work well for my car. I may have ran the EGT's higher than most...who knows. If you ask any WB manufacturer they will tell you it is not recommended to put it directly after the turbo. Just because you have done it, doesn't make it correct.



PLX see step 3... they suggest 24 inches!

On TURBO CHARGED vehicles:
The maximum temperature of the sensor at the bung (the sensor hexagon)
should not exceed 500 oC or 900 oF. If these temperatures are exceeded in your
application you should either install a copper heat sink (instructions below) or the
Innovate Motorsports Heat-Sink Bung extender (HBX-1).
The bung extender is recommended for situations where airflow is restricted or
the encountered heat is higher than a heat sink can handle.

Sensor Placement
A weld-in M18 X 1.5 boss is supplied for sensor installation. Mount the O2 sensor in the
exhaust system at least 18 inches downstream from the exhaust port. If you anticipate high
EGT's (over 800C), run a turbocharger, run at high RPM for extended periods of time or plan on
running leaded race fuel then you must mount the sensor at least 36 inches or more downstream
of the exhaust port as all of these can cause the sensor to overheat.

So my current setup is a small 16g @14 psi. I don't have link and will be picking up a wideband to monitor my a/f. Whats the recommended install point? I'm not sure of my egt untill I pick up a gauge or a logger. Speaking of loggers any ideas?
