Few mods...mapping??
 

Hi guys,

Whats the score with the ecu mapping when a few mods are made, such as Green panel filter and the airbox resonator removed?

Does the ECU adjust itself accordingly on these? If so to what extent will it adjust?

Will the engine run weaker/leaner?

Sorry, I am new to modern cars (carbs and jetting has been my life so far!).

Also, will I see any gain with a Green panel filter? Anybody rate these? The resonator is removed mainly for the deep induction noise! :D

Cheers

Dan

Mild mods such as those you've mentioned the ecu will adjust the AFR.
