Scanmaster is made by Bob Bailey. You can Google him to find his website...Bailey Engineering. Steve Wood put together a very informative website. You can also converse with him on Face Book.
Is it a stock ecm or aftermarket? Makes no sense for a stock ecm to have a logger ie; Powerlogger added to the stock ecm and not run a Scanmaster as well. Take a picture of the ecm and post it.
