Since it does so much, we should have a subforum for using ForScan.
What kind of hardware are you using? Apple, Mac, PC, laptop, Android tablet, Microsoft phone, Motorola, Samsung, et cetera? Bluetooth, WiFi, physical cable from OBDII to your computer? Which brand or source for your OBDII connection equipment. What did you do with the application? Step by step to help the next guy. Maybe screenshots.
Looking forward to Transit Connect specific task performed with ForScan. Or maybe some other app or program which you are using, and care to share the knowledge with the next guy.
