Eclipse Cross, 2018, SE
Latest firmware for starter and bypass. Loaded recommended options and confirmed the options specified in the setup PDF for the car were set. Using the MITS2 harness.
3x lock works for remote start works.
Tried various (3?) methods of syncing, all of which seemed to work, however, device still only shows it's own information (battery voltage, GPS, and "connected" icon)
Yes, using the crossover cable. Yes using the right port on the evo-one (blue).
Tried sending the unlock command/lock command at the last steps of the sync. Door open and door closed. Didn't seem to matter.
Tried switching the protocol in the app to something else then back to Fortin.
Confirmed the "datalink" protocol is Fortin 2
Previously, this carlink was used with an evo-all for a different car and it worked great. Now it does not.
