How to read fuel trims?

[tbonitz301]

I am using pocketlogger to log runs, and i am curious if you can determine your IDC by looking at your fuel trim(s)? I dont have much experience with this so bare with me.

Nope.

I didnt think so. Anything else i could tell from watching my fuel trims? Just read your write up on upgrading the fuel system. Good stuff

If you have a SAFC or DSMLink then you can get them closer to zero, which means that your ECU in closed loop operation doesn't have to add or subtract extra fuel to maintain stoich.

Cliffs: it makes WOT tuning easier

If by IDC you mean injector duty cycle, the Pocketlogger should be able to log that independently. You can choose it to display is pulse width or duty cycle.

Not for a 2g.
