Will reprogramming the speedo result in a VIN lock?

Hey Bob, I'm wondering if I can do a ECM update and speedo calibration on a friends ride and not vin lock my smarty? S03 Thanks!
 
If you do anything with the ECM program it will lock the VIN, or at least that is my understanding.
 
So do you loose the 3cyl high idle when you return it to stock? I was thinking that it updated not just replaced the factory programing.
