Link CAN Gauge Daisy-chained to AEM X-series Wideband

[nate240]

Hi guys, searched first but wanted a more solid answer to my specific set up. So it seems to be do-able to connect these two devices but with how important an O2 sensor is for tuning I want to make sure my setup is solid.

So I have the AEM X-series Wideband (AEM-30-0300) and Link CAN Gauge. I was going to use the analog input but since the X-series is able to use CAN, I'd prefer that.

Current setup:

- One port of the Link CAN Gauge has a cable connecting it to one of the CAN ports directly on my plug in ECU

My idea: buy a Link Daisychain cable (SKU 101-0227), cut one end off, splice the flying leads to the GREEN/BLACK and WHITE/BLACK CAN high and CAN low from the X-series Gauge, and plug into the open port on the Link CAN Gauge.

Questions:

- I only need the 2 CAN High and CAN Low wires? (I would be joining the the wires directly off the AEM pigtail, not T'ing into, and de-pinning all the other wires off the daisychain cable)

- The terminating resistor on the CAN Gauge, should I plug the wire connecting to the ECU next to it, or should i plug in the daisy chain cable there, or does it not matter?

Thanks in advance!

Yes that will be fine provided the AEM gauge is getting its power supply from elsewhere.  Only the two CAN wires are needed.  Either connector on the back of the gauge can be used.

Hey @Adamw thanks for the response I did what you confirmed but now I'm running into another problem. I saw some of your older posts saying that the GaugeART gauge config is fixed at 1Mbit. So my problem is that my X-series also seems to be fixed at 500 kb/sec. I'm hopeful there has been an update since. Is there a solution other than using two separate CAN networks?

There is a 500K config in the gauge app.
