Just been out dicking around with my M509 to check codes etc. Was looking to see if it showed me misfires... Which it does, and told me 1 misfire on Cyl 1. Great, it told me what i wanted to know.
Now, is there any freeware/payware software which i could use to display recorded data from the M509 unit onto my PC? The Autel software is pretty much for updating the unit only.. No capability to show recorded info etc.
