2.4 EFI BP analog ECU question

[Carter Powell]

On my ECU box there is a white plastic plug about three inches from the top. Under it is what appears to be an adjustable slotted screw. What is this for? If it is an adjustment for fuel how does it work and how do you tell if it works?

Many Thanks, Carter

I wouldn't mess with it unless you have a tester to see what your setting it to. Could cost you a motor rebuild.
