Hi.
I am all new to setting up custom canbus devices.
Need help to configure WB2 canbus lambda to my Yourdyno ecu.
Would be nice if someone could tell me how to do it.
Yesterday I got the following info sent to me from Haltech support.
What the text does not tell is that Haltech always use "Big Endian". And that all WB2 devices are sold as WB2A (id 0X2B0)
