HPTuners MPVI 3 is a device/software suite that allows you to read and write your ECM/TCM. This interface connects to the cars computer(s) to a laptop that can read/write the computer file.  This will still require someone that knows how to adjust the tables correctly without damaging your engine and/or transmission.  We offer a performance tune for nearly every GM car that this will work with available on each specific platform page.

How that works...  You would get the software for this installed on a laptop, connect the cords to the laptop, key the ignition on, open the editor, click Read VCM, save the file, and if you purchased our performance tune, email it to us for tweaking.  We will then edit the file and email it back, you will then flash it onto your car.  The next step, is to scan it and email us the scan, we will tweak the file further and email you the revised file.

Credits: To be able to "license" your vehicle it will require a specific amount of credits ONE time (once an ECM is licensed you never have to again).  Each vehicle is different, it ranges from 2-8 depending on the year and trans.  Click the following link to determine the credits required.  Supported Vehicle List  Quick reference: 3800 cars 2, Cobalt/Ion/HHR 2, 11-15 Cruze/Sonic 2, 16+ Cruze/Sonic 4, 13-15 ATS 2.0 2, 16 ATS 2.0/ATSV 3.6 4, 17+ ATS/ATSV auto 8, 17+ ATS/ATSV/Camaro manual 4.

This is only the hardware needed to start remote tuning with us. If you would like us to tune your car you will still need to purchase one of our 1.0 PCM tune files with the "email me a file" under the core charge option and to have the appropriate credits to license your ECM/TCM etc.
