The fact that you have probelsm with vibration indicates some type of loose wire somewhere. Possibly a ground. You may also have some errors on the laptop as hard drives to not like vibration.

I do alex. This car has been giving us nothing but greif and I'm not so sure that its my computer but more like ecu itself. This is a PITA as i have to disconnect and connect the usb cable everytime the software locks up. :(

this is the EXACT same problem that is happening with this car we are trying to tune on the dyno. :?

I still have a connectivity problem even if the car is off but key on and make multiple changes, it says it's still connected but the upload screen doesn't flash unless I unplug then plug back the usb, do I possable need to change some type of port setting. Like I said in the beginning it worked fine always

we used another laptop and it worked perfectly. we believe that the problem lies within USB itself. If you're running 1.0 then the connection will freeze or show you that you're online but not showing any status. When we used the new laptop with 2.0USB, we finished the tune much quicker without having to plug and unplug the cable all the time. HTH.

I don't have this problem ever with s200
