(typically you get what you pay for so I am not expecting to be able to find anything free..)

So why am I looking to go this route? There are other easier ways to find power. The big reason is that I am just looking to learn more about ECUs and how they work, as bonus hopefully ill pick up some ft/lbs and mpgs.


Any input is appreciated, thanks!
I been around here a while, & to the best of my knowledge, no one has ever successfully messed with the stock ECU...

However, I have heard of those smarter than I, using aftermarket boxes with success...
