hi guys new here, just installed a can lambda on my g4+ storm, i have gone into the can setup, module is present, it finds the module but it doesnt read any data from module, no lambda data at all i have tried changing it to another lambda source and can bus identifier but still no joy, it works , powers up if i disconnect it it dissapears off the can bus, but still no reading i think im missing something just run out of ideas, any help would be appreciated
