Change Computers

[IMAY2023]

I don't think OEM is saved on the server for each car, I have changed computer and return to OEM option didn't returned it so I had to revert everything manually, to save configuration file as OEM, and now when I need it, I just load OEM cfg file...

So something isn't right about this story...you see, it's actually impossible to Restore to OEM and have any config item be different than what it was originally. It can't actually happen, because it doesn't work that way. (*)

When I "restore to OEM", my tire size is wrong (I have 265/35R22" from the factory), the alarm goes to disabled (also an option from the factory), and one more option also goes wrong (can't remember exactly)...
But never mind, maybe somebody messed with the config before me, it is good to know that "restore to OEM" is always the correct choice before visiting the dealer, regardless of the settings in it.

Two things, 
1) Tyre size. If you have a different wheel and tire size than the factory OEM, my suggestion to you is  this. Get a VIDA subscription and under the functional changes TAB, install the correct tire size. It does not cost much. Wrong tire size setting will cause problems with odometer, ABS, traction control and etc.  
2) If you leave the Alarm connected to car while VIDA reads the car, it will force you to reload it under HW changes before allowing total upgrade.  This does not mean your car will be blocked for software update / reload.  I do not know the price of Alarm software (without IMS - internal motion sensor). If you mean retrofitted IMS (Internal motion sensor) by  " the alarm goes to disabled" , I suggest you disconnect it before doing read out from VIDA. Otherwise, VIDA will force you to do Reload IMS (costs $250 USD) or reload "Remove IMS" (costs $90 USD) before allowing total upgrade.
