How to Reset the ECM
After watching the Smack resetting the ECM and getting a huge increase in mpg, I started looking up how to reset the ECM. There are a few different ways, but they all pretty much say the same thing, just in different ways. The majority of the info I gleaned was from high performance car sites where people add after market parts and need to reset the ECM so their vehicles will adjust to the new equipment and variables. Hopefully this will help us with our cells/systems. BTW I am NOT a mechanic or an electrician - IOW this is for informational purposes only! Use at your own risk cause I am not liable for anything you do. Peace, Steve aka AlmostHydrogen
