Andre K Posted August 24, 2023 Report Share Posted August 24, 2023 Hi, I am trying to get my AEM 30-0313 GPS Speedo gauge to read vehicle speed inside Link. I currently have it wired into the ecu via the CAN plug as the AEM instructions show (attached below). Can someone help me with the setup inside of Link to get speed to work? Not ideal, but this is a temporary solution until I get driven and non driven wheel speed from the car itself sorted out. Also, I have a BTI display in place of the factory dash, is there a way for me to use the AEM GPS Speedo gauge to give the Link ecu a speed reference as well as giving my BTI display a speed signal to show speed? Thanks for the help tune7 AK.pclx IMG_4640.HEIC Quote Link to comment Share on other sites More sharing options...
DerekAE86 Posted August 24, 2023 Report Share Posted August 24, 2023 Do you have any other devices on the CAN bus? Because looking at the instructions quickly shows the gauge doesn't have a terminating resistor in it. Which means if it's the only device on the bus you'll have to add one into the loom. https://www.aemelectronics.com/sites/default/files/aem_product_instructions/30-0313.pdf The instructions are actually pretty good for setting up the CAN streams. It's just translating the message id. Seems they're using 29bit id CAN message id though. Haven't experienced that myself yet so curious to see how the admins help you set that up.

Is that just HEX byte1=000A byte2=0000? Which would translate to a Dec id of 2560? Or 655360? Quote Link to comment Share on other sites More sharing options...

Adamw Posted August 24, 2023 Report Share Posted August 24, 2023 Is the GPS speedo wired to CAN 1 or 2? Quote Link to comment Share on other sites More sharing options...

Adamw Posted August 25, 2023 Report Share Posted August 25, 2023 Try this. GPS speed will be received as CAN DI Freq 8, and that is set up as the source for both driven and driving wheel. Number of satellites is received as CAN AN 8. tune7 AK With CAN GPS speed.pclx Quote Link to comment Share on other sites More sharing options...
