Definition of STFT

Hondata I looked in the help contents but just to clarify when you have a negative number for STFT that means the fuel tables need to be reduced and the ECU is pulling fuel?

It doesn't really say what negative and positive values are in the help section

Kinda confusing be cause TRIM means to me a reduction ,so 5% trim could mean a 5% fuel being pulled.

Yes, a negative number is reducing fuel so the maps are too rich.

Thank you. -5% stft is pulling fuel out...That's what thought


Kinda like the thing with timing.....5 degrees retard is actually a reduction even though it's a positive number
