setup for 30-0310 UEGO with EMS 2

Hello all,

I have a 30-6052 EMS 2 and combined it with the 30-0310 UEGO inline controller and the included wideband O2 sensor in my Honda S2000, per recommendation from AEM personnel through the forum (back in 2016).  I have been experiencing some issues with the car and think it may be due to the EMS not being setup correctly.  I have gone back to the setup wizard and found that the list of available O2 sensors does not list the 30-0310 inline controller, but does list an 'external controller' and also has a '30-2310 inline controller', amongst other options.  I currently have 'external controller (PN 30-2300/2301)' selected, is that correct?  I am now thinking that my tuner should have selected the 'Inline Controller (PN 30-2310)' instead?

 

Thank you!

You should select the 30-2310

You should select the 30-2310 scale as the 30-0310 superseded it and has the same O2 scale.

I too have the 30-0310

I too have the 30-0310 controller with aem v2 for my Supra. How would you calibrate the "O2 Sensor #1 Cal" table in AEM? I know for past AEM widebands it was common for the AEM gauge to show a different AFR than what showed in AEMTuner. IE the wideband gauge may show 14.0 and in AEMTuner it may show 12.7. With the old gauges you could unplug it and it would go into some dummy mode which would output a constant 14.6 AFR. Then in AEMTuner you could select the entire "O2 Sensor #1 Cal" table and increase-decrease it so that it also matched 14.6. After doing this and re-connecting the gauge; both AEM Tuner and the Gauge would show the same AFR.

 

So the 30-0310 Wideband Controller does not have a gauge. Without a gauge how do we calibrate the "O2 Sensor #1 Cal" table AEMTuner to it? Is there something we can do to trigger it sending a static AFR? (IE if I unplug the o2 sensor should it output a particular AFR)?

 

Thanks

fastfalcon94@gm,

fastfalcon94@gm,

If you are getting skewed readings, you can test at full rich and full lean values to make a small adjustments, also make sure you are using the brown&white analog output -/+ wires.

I am using the brown/white

I am using the brown/white wires. The readings are ball park I'm sure. I would feel better if there was a way to fine tune it. I'm thinking back to my other car where the delivered O2#1 cal table for the exact part# o2 sensor selected in the wizard still needed to be adjusted to match what the AEM gauge it was getting it's signal from showed.

Here we have a new part# that doesn't show in the wizard. We've been told to select an older part# that the new controller replaces. It would be cool if there is a way to lock the sensor at a fixed reading just so we can skew the table a little one way or another. I tried unplugging the o2 sensor and it showed 8.5 AFR in AEMTuner. I don't know if that is expected or not. I'll look more into the full rich/lean tests.

Here's an old thread on this forum where they mention the CAL procedure I talkeda bout. Seems like older AEM gauges would default to 14.6 when the sensor was unplugged. Maybe this was a safety thing.

Hey Falcon,

Hey Falcon,

I have attached the instructions for both gauges below, the Voltage to AFR scaling both use the same formula AFR = 2.375(V) + 7.3125. So selecting 30-2310 is the right way to go.

Here are the 30-0310 instructions(see page 6) : https://www.aemelectronics.com/files/instructions/30-0310%20X-Series%20I...

Here are the 30-2310 instructions (see page 4): https://www.aemelectronics.com/files/instructions/30-2310%20Inline%20Wid...

Leaving controller powered on (engine off / sensor connected) will result in a full lean reading of 18.0 AFR (4.5volts)
