Connecting Infinity to X-Series AEMNET Gauge

I don't see a connector on the Infinity that the cable that comes with this gauge is supposed to connect to. There are two connectors on the cable supplied with the gauge (on the none-gauge side of the cable), but I don't see where they would go.

What vehicle do you have an Infinity on? What are you using for a harness?

Thanks for responding.

Thanks for responding.

It's on a 1999 Viper. The harness was made by Racing Solutions Inc, who I also bought the turbo kit from. I did have then add a CAN bus connection, but it just ends in wires, no connector. It sounds like I need to buy the connector and wire it myself. Mouser.com carries the connectors. Why are there two connectors on the Infinity side of the supplied cable? Are there both genders so that you can connect to a male or female connector on the Infinity?

Both genders are on the cable so you can daisy chain multiple AEMnet devices together. Yes, you'll need to add in the appropriate connector to get them mated up.

Is it possible to daisy chain 2x AEMNet devices where one is an output (XFinity Gauge feeding data) & the other is an input (AEMNet CAN Gauge receiving data)?

If so, how would I wire this up? I'm currently using a AEM RB26 PnP harness

Yes - that's the beauty of CANbus data streams. Tx and Rx happens on the same two wires. Connect all CAN- (CAN low, typically green) circuits together and connect all CAN+ (CAN high, typically white) circuits together.

I take it 'XFinity' is X Series?  If so, which X Series gauge are you using?  Right now the Infinity is only setup to receive data from the X Series Wideband O2 gauge.

Yes my mistake. It's the X-series gauge. P/N 30-0300

That's really good news but I don't seem to understand. Looking at the physical connectors, I see :
1. Female AEMNet Connector from Infinity 506   2. Male AEMNet Connector from CAN Gauge    3. White/black AEMnet+ & green/black wire AEMnet- wires from UEGO gauge

How can I daisy chain the two gauges together and feed/receive from one AEMNet female port?

If you don't mind waiting a

If you don't mind waiting a couple days, I can draw you a schematic on Monday but basically you'd add a male and female connector to 3. It'd act as a pass through and go in between 1 & 2. The power and ground from 1 would need to pass through to 2 but does not need to go to 3 since the gauge has it's own power. The CAN wires would pass through from 1 to 2 and 3 could also tap onto those wires as well.  It's pretty simple but might be hard to visualize.  Draw it out yourself or wait until Monday and I can get you a drawing.

No I do not mind waiting for a diagram if you can shoot one my way :) Thanks a lot!

Thanks for the reminder. Here

Thanks for the reminder. Here it is:

And just to be very clear, the UEGO gauge can NOT get it's power and ground from the AEMnet connection.  Only it's CAN+/- wires can connect with AEMnet.  The UEGO and AEMnet gauges do not have terminating resistors (but the Infinity does) but assuming everything is within close range of each other, it probably won't be a problem.  If you find that data tx/rx starts getting spotty, try adding a 120ohm resistor across the CAN+/- wires at the furthest physical device.

I have successfully wired it

I have successfully wired it up the way you suggested. However is there any steps I need to take to let the Infinity know of its existence? And do I need to set up any base parameters?

Right now the ECU shows a Lambda/AFR of 87. So I don't think it's reading right

I have the same question. Got it all wired up but see no real option to make the ecu use that input. The current readings from the gauge are off %20 from the ecu readings so I dont think it is communicating or pulling the information correctly

Did any one ever PM you or something? I still havent heard an answer to this one.

Currently the Series 3 & 5

Currently the Series 3 & 5 Infinity ECU's are able to accept UEGO inputs via AEMnet using v96.3 firmware. The new firmware release that's pending for the Series 7 will have this functionality added.

Hey I'm looking to add a GPS module to this exact same setup shown above. I have both my CAN gauge & wideband gauge working perfectly., receiving outputs from ECU and feeding inputs to ECU, respectively. 
Now I have one extra GPS module that I need to daisy chain into this AEMNet channel as an input to the ECU and was wondering how to wire it up?
Is it easy as splicing in the CAN + and CAN - to the same wires on the extension harness along with 12v+ &gnd?

Looking forward to your response
Thanks
