Need some help with Light client... Need to find 2 WBo2 sensors on canbus

Hi, I am new to CanBus. I recently bought an EMUPro and have it currently hooked up to a SXS and have it running. I have 2 aftermarket 4.2 lambda sensors that were on the car prior to the EMUPro hooked up and running (standalone system for them). The sensors are currently connected to the Dynojet controller that they came with. That controller then plugs into the powervision 3 and I can read the sensor data there. The problem is I want to connect them to the EMUPro via canbus. I am wondering if someone has some good direction on how to use the Light client to find the sensor data via light client. I do know that the sensors controller sends the data to the power vision by CanBus. I can conect to the canbus with the second CanBus connection on the EMUPro but I get lost at that point.

The current Dynojet components I am using are Powervison 3 for a KRX1000, a Dual Channel Wideband-PV3 Kit for Polaris(I got this from a shop that modified the plug to allow for the KRX to send can data and power the WB controller).

I was thinking I could remove the CanBus wires from the stock part of the car to eliminate addional sensors being read on the canbus while I am looking for the WB sensor data. At that point I should only have the 2 sensors on that canbus. I have tired this but was unable to figure out the next step to show the can data from that controller.

The reason I am trying to do this is I already have this stuff and want to be able to tune/log per bank on the car but don’t want to buy more of the same stuff if what I have can work for what I need.

Hi,

let’s start with the requirements for CAN bus:

  1. Every device in the same CAN bus must use the same bit rate (1 Mbps, 500 kbps, …)
  2. CAN messages sent by a device must have an unique ID not used by any other device in the same CAN bus. If there is some ID conflict, these IDs must be changed.
  3. To use data from the CAN frames, you need to know the data structure. Look for it in controller’s manual.

Light Client allows to configure and supervise simple Ecumaster devices as well as receive all the CAN frames from the bus by using one of the supported adapters (eg. Ecumaster USBtoCAN). You can use it to watch the frames from WBO controllers.

If you know the IDs of the frames from the WBO controllers, you can receive them in EMU PRO. In a Project Tree add CANbus Receive Frame, choose CAN1 or CAN2, set ID and add channel. In the opened window configure the channel - its location in the frame, some factor etc. This channel would be visible in EMU PRO like any other channel.

This is great information. I am not able to work on it for a few days as I am traveling for work but I will be looking into this as soon as I get a chance. I really appreciate the info and quick response.
