Scan Tool - Wireless - Xtool D8W - Graphics Demo. Record 8 PIDs while test driving. Choosing a Scan tool can be confusing. There are many to choose from and they have good capability. It is hare to tell what the graphics recording is like from the sales info. I decided to give Xtool a try this time. My old scan tool served me well but the hardware is limited so time to upgrade. So far so good. I haven't spent much time with it yet. I purchased it from Amazon. I have not been compensated for this review.
