Vitalka Posted August 20, 2020 Report Share Posted August 20, 2020 Hello, first time poster. Currently running BMWLink E36X ECU in my swapped turbo E30. Got my GaugeArt CAN gauge today and plugged it in. Link Can Lambda is connected to CAN 2 OBD on the ECU and shows up CAN Devices. Gauge is connected to CAN/RS232 on the ECU. I enabled ECU Telemetry as per GaugeArt's instructions and set it up to show AFR, IAT, Oil Pressure and Boost. For some reason, the gauge is non reactive and not showing up in CAN devices. What am I missing? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 20, 2020 Report Share Posted August 20, 2020 It will never show up in "find devices" as that tool is specifically for finding Link CAN products, it wont find 3rd party devices. Can you attach your tune so I can take a look? Quote Link to comment Share on other sites More sharing options...

Adamw Posted August 20, 2020 Report Share Posted August 20, 2020 Note your ECU is a G4+ not a G4X, I will move this thread to the correct forum shortly. Your ECU is configured correctly according to GaugeArt's instructions, but the ECU is receiving no acknowledge from the gauge. This can be caused by many factors such as the receiving device set up incorrectly, but most commonly it is a wiring issue such as H/L swapped or connected to wrong pin.

Thanks for moving the thread to the correct forum. Can you take a look at the connectors? 5 wire connector is for Can Lambda and connected to Can 2 OBD. Two wire connector is for the gauge, the harness came from GaugeArt. It's connected to Can/RS232. Do you see anything wrong with the wiring?

Adamw Posted August 21, 2020 Report Share Posted August 21, 2020 I dont see anything wrong there. I think you will have to get in touch with Gaugeart now to see if they can offer any troubleshooting advice. The ECU setup and wiring looks correct. I assume you have programmed the gauge for the correct ECU protocol etc? Quote Link to comment Share on other sites More sharing options...

I assume it came pre-programmed from them, but will get in touch with them today and update. Thanks for your help Quote Link to comment Share on other sites More sharing options...
Vitalka Posted August 21, 2020 Author Report Share Posted August 21, 2020 One thing I forgot to mention is GaugeArt requires a 120 ohm resistor https://gaugeart.com/instructions/gaugeart-can-gauge/terminating-resistor-configuration/ which I don't have. Could that be the issue? Quote Link to comment Share on other sites More sharing options...
Vitalka Posted August 21, 2020 Author Report Share Posted August 21, 2020 Also, when connected to PC Link I get error code 14 Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 21, 2020 Report Share Posted August 21, 2020 It is unlikely the lack of terminating resistor would prevent communications but it is correct practice to have one so you should fit one. I have come across some devices that are very sensitive to termination. Error code 14 is AN Volt 2 at ground. If you clear the fault codes does it come back? It could be caused for instance if you had unplugged your TPS at some time in the past. Quote Link to comment Share on other sites More sharing options...

Do you know if G4+ has 120 ohm resistor? The gauge does Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 22, 2020 Report Share Posted August 22, 2020 Yes the ecu has a terminating resistor built in. Quote Link to comment Share on other sites More sharing options...

I had to send the gauge back to them and got it back few days later. Looks like my gauge had a faulty board which was replaced. Connected it to the ECU, set it up and everything is working great.
