I have a simple question about tuning the idle of a ford focus SE within HP Tuners. Within the editor, I am able to only adjust the long term fuel trims. What I need to do is adjust the fueling by 50% based off of the short term fuel trim being at 50%. What should I adjust in order to achieve a nice idle? Logs attached
it seems your engine running too lean might be mechanical issue, are you using stock injector? what is your mods list, is the intake stock?
It is currently on a Ford RS throttle body, Ford Focus ST injectors, Intake manifold and a CAI intake that has the same diameter as the stock intake tube.
can you send me your tune and stock one i will see if i can help you
Here is the current tune file I will add the stock file when I get home
