I have to tune my customer's car and its has a ms1 on a Mazda mx-3 klze. Actually i've been able to link the megasquirt to tunerstudio!!! I'm seening my gauges and all but i dont want to do any changes cause im not sure of some things. Do i have to import the ms1 tune in tunerstudio or does it is already in when tunerstudio recognized my ms1 and baud rates etc? What i mean is if i do a VE change will it take all the infos of another tune in same time and burn it in my ms1 and erase my actual tune??? Thanks for your help guys.

TunerStudio grabs the tune on the ECU when you first connect. You will want to save a copy of it before you make any changes; it's simply good tuning practice.
