The unit can connect to [TunerStudio](http://www.tunerstudio.com/index.php/tuner-studio) via native USB communication. You can either plug a MiniUSB
(or some boards have MicroUSB) cable into the top of the unit. This is a bit difficult to get to in the stock installation position on an NA6, so it may not be ideal for a permanent installation in the stock location.
![Micro USB connector](Hardware/pnp_microRusEFI_48na/MRE_Micro_USB.png)
If you want to use this connector for communication with your tuning laptop, cutting a hole in the top for connector access is helpful. Here are some rough dimensions on where the hole should go. A 5/16" or 8mm drill and a small file or Dremel works well.

Alternatively, you can wire a standard USB cable into the main connector for a more permanent solution. Your board may come with additional contacts / wires for the main connector that can be soldered to a standard USB cable. (Please note that the 5V connection is not needed for communication. It can, however be used to power the MRE unit with the ignition off. The 5V power suply feature is untested and may not work. Communication using GND, D+ and D- is confirmed to work.)
