HP MPVI3 Diagnostic Code Scanner and Tool with No Credits

Very easy to go into the editor and do your tuning changes. BUT don’t be fooled into thinking any idiot should be messing with the numbers. One must research and understand exactly what you’re changing and why or you could easily ruin your car. If you do know what you’re doing this is a great tool to make fast changes and do road tunes for yourself and friends or dyno tunes if you have access to one. This device will absolutely not hold your hand but you can learn to tune without blowing an engine if you’re patient and careful. I knew 0 but tuned a friends turbo’d luxury car with a safe and high performance tune after just a few days of research.On a side note the device is a little chunky so you may need a OBD2 extension to plug into the tighter located ports. Came with a long USB C to A cable for a laptop, a lanyard and a sticker. The hardest part of using this device was logging into HPtuners website because their captcha was awful to get working. Also you have to pay to license cars individually and the cost and support varies per car.

Tuned my 2017 Sierra. No issues with the unit. Loaded credits and started to click the tuning buttons!Thanks again
