Bought an obd2 scanner to id an mil (which later went away) and got drawn into learning about fuel trim.

Why vehicles use fuel and how can fuel economy be improved? This value is a more accurate indicator of how the fuel mixture is being corrected to compensate for changes in the air/fuel ratio that are occurring inside the engine. Got a reply from haltech yesterday which got the ltft work

Fuel economy is measured in miles per gallon (mpg) and is a measure of how efficient a vehicle is at converting fuel to power.
A Negative Fuel Trim Percentage Indicates A Taking Away Of Fuel While A Positive Percentage Indicates An Adding Of Fuel.
Got a reply from haltech yesterday which got the ltft work Since the new fuel injector is about 8% bigger therefore the negative fuel trims by about the same percentage points. However, you need to drive at least 50 miles before you start to see the fuel trim report.
