Just bought a OBD link MX and downloaded the Motoscan APP. Seems to work well for resetting service reminders and deleting fault codes. What else can it do? apparently with MOTOSCAN and an inexpensive TPMS relearn tool you can change the TPMS sensors and mate them up with your ECU. Anyone done this or been able to log fuel trims? Would like to hear from inmates that have used this APP and their findings.
