i aim to just put it back to standard when it gets there, get it complied, then return it to eco-unfriendly but more fun mode
so back to the question...do I need a specific version of the L8 ecu to run a lambda sensor or will any L8 do?
Well if a L8 won't pass the test, WTF are you going to do to get it passed?
The ECU fuels for what the car needs!!
The way Stu utilises the closed loop lambda is the origional strategy in the ECU's operating system so all L8 ECU's operate the same once they have closed loop lambda activated......wether on a standard map or Stu's map.
Like Gus says they all, including standard revert back to normal mapping if the ECU sees sharp throttle movements, RPM above 4k, boost above 4 psi or full throttle....
