Wideband Can Bus now available for the STM Pro ECU

Is any data available other than lambda from the can stream? Diagnostics? I would like to implement a strategy to deal with sensor failures in tuner studio.
The is no Diagnostic data for the wideband over the can bus. Only compatible can bus controllers are RusEFI and AEM and only basic functions currently.
In what way is can the CAN bus data be configured? Address. byte sizes etc etc
Or can the data be suplied so we can configure other devices
Hi, there is only can bus broadcast for the ecu, Haltech broadcast is available for external devices, BMW or VAG basic for clusters. It is not configurable. You can add addresses for the ecu to receive can bus for external can bus things like gauges or digital switching output of the ecu.
What is it you need exactly?
All parameters are received as 16 bit unsigned integers.
A CAN frame holds up to 8 bytes of data which means each frame can hold up to 4 parameters.
Each parameter must occupy 2 bytes.
basically i need to be able to send the O2 sensor data to a address the ecu is expecting and also the data to be in certain bytes with the message
address 1254 bytes 1-2 Lambda 1 La
address 1254 bytes 3-4 Lambda 1 La
address 1254 bytes 5-6 Lambda Target La
1255 1-2 Lambda 1 Short Percentage2
1255 3-4 Lambda 2 Short Percentage2
1255 5-6 Lambda 2 Long Percentage2
1255 7-8 Lambda 2 Long Percentage2
