I watch a lot of Mighty Car Mods, which is an Australian YouTube channel where they do mostly cheap and DIY modifications to cars. They like to replace the stock ECU with a Haltech ECU so they can further control all aspects of the engines performance.

I want to see what can be done for the Honda Insight to further raise the MPG by programming an ECU to run in lean burn mode more consistently. No dropping out of LB to purge, enable LB at lower RPM, etc.

When I had the Passat, I messed around with tuning the ECU for better MPG and performance. I was able to raise the horsepower from 150HP to about 230HP where the injectors couldn't keep up with the amount of power I was going for under boost. I also went from 29MPG stock to 48MPG highway by running my car really lean under no boost and using hypermiling techniques.

Is anyone else interested in getting an ECU and giving this a shot? I'm thinking of keeping the IMA system but finding a way to fully control it for max power at take off and lower gears since this is where the Insight loses most of its efficiency.
