Exactly. I wouldn't be cutting and splicing wires in a brand new car. Megasquirt, for all it's advantages, is nowhere near as good or as sophisticated as a new car's management system. It won't run most of the systems in the car (Automatic transmission, gauges, A/C, cruise control, ABS, traction control, etc.) and would create an epic mess that you would then have to engineer around. Plus, you will void your warranty and no longer be able to pass an emissions test. It's also crude and would likely result in lower MPGs than your factory computer as it lacks the ability to run a sequential fuel injection system. It can run in either batch fire or disynchronus batch fire (basically 2 injector banks) modes. If you have a 2 cylinder engine this is great. for a 4 cylinder, not so much. Save Megasquirt for older cars with engine swaps that need an easy solution for engine management. I would just get a Scangauge and use it to adjust your driving style. Plus, if you really wanted to use a car for eco driving, why did you go with an automatic transmission? You would have been better off with a CVT or a manual or a hybrid model. For that matter, the Insight would have been a better choice all together. Similar price, much better MPG.
