If you already have a MotorOps AutoCal just use it.
The AutoCal will hold up to 8 different vins, which you can use it separately on 8 different vehicles.
If your tuning different vehicles, you’ll have to load the tunes you want and save what was in the AC.
This is where EFILive scan & tune and EFILive explorer comes in handy on your PC saved in your desktop the easiest place to remember IMO.
Then all you’d have to do is pay for a vin license and tuning for your Dmax.
MotorOps should be able to show you how to add another vin in your AC.
I’ve done this a couple of times, but with the help of the EFI tuner walking me thru the process.
