Post Fuel Trim Questions/Issues
on: November 17, 2013 (GMT)

So I deal with a LOT of generic OBDII tools and diagnosis.

I usually look VERY closely at Fuel Trims when working on any car.

What I have found with Torque is there are 3 Fuel Trim categories.

Short Term Fuel Trim – Seems to agree with all other OBD tools I have and use.

Long Term Fuel Trim – Not sure what this valve typically represents as it is no Long Term Fuel Trim as I regularly deal with it on other OBD tools.

F/T (Fuel/Trim) – Which appears to be Long Term Fuel Trim as I know and use it with all other OBD tools.

Could someone please explain the difference in LTFT and F/T with regard to the Torque Pro App?

I am hoping this is something that Ian can clear up.

Thanks in advance.

I am using Torque Pro 1.8.205 with no
predefined pids added and I don’t see
a F/T listed in Torquescan.

Have you loaded custom pids which use
F/T as a long name?

(Torquescan shows the pid associated with
the long name – might help to know this
info)
