I'll try re-installing the download from website and see if it is new version, the info on website is old version and download is same name...

What do you mean "My WB is powered/grounded via PCM."
PCM is grounded to engine, WB should be grounded to engine. Preferably same ground lug/bolt.
Not sure how to power WB from PCM? Or if it should? A trigger from PCM for relay is what I do, other then that It's probably not a good idea? Not sure, never did that or tested...
