12077, fuel trim
Posted by VX100, Jan-14-02 06:14 AM
Since I have looked at the different signals my new pocketlogger can read from my car, there are two values are called "low fuel trim" and "high fuel trim."

I don't know what these mean. Are they the same as injector pulsewidth?

low = short term fuel trim.
high = long term fuel trim.

I'm sure you've read all about it in the tech manual, but if not.. that's the place to go. I'd likely explain it wrong if i tried to off the top of my head.
