Megasquirt MS3PRO Standalone Systems for GM LS Engines

SETTING UP AND TUNING AN EFI ENGINE for ludicrous power used to be something best left to a dedicated tuning shop. They handled the wiring and programming and tuning—and charged you a pretty penny to do so. And that is still a valid way to set up and tune a serious EFI engine. But thanks to DIY Autotune, there is an alternative. The company makes programmable engine management systems based on the tried-and-true Megasquirt architecture that gives you the tools needed to dial in your engine for maximum power and performance. If you have the patience and willingness to learn, you can do the tuning you used to pay someone else to do for you.
