How would i go about looking at LTFT? Would that be af learn 1? If so that stays at 2.34 on idle and 0 at wotLooks like you are describing short term fuel trim. How does the long term fuel trim look?
My LTFT shot up to +25 at idle and low load when the fuel pressure regulator vacuum hose popped off.
I would not drive it.AF Sense 1
Now at cruise sits high at 20s
Before it would be around the 14s at cruise . .
My commute to work is about an hour one way, just worried if im really running "Extreme lean" that its going to cause damage
I would not drive it.
I'd replace the MAF - and check fuel pressure - and then be partially stumped . . .
SD only or Hybrid? If SD only then MAF not used, perhaps not present. Hybrid? I'd replace MAF. It's active at cruise.Also forgot to mention, if it matters I’m running a speed density tune. Full bolt ons, upgraded piping etc.
I recall the tuner had issues with the MAF, I think replaced it? Can’t remember but end up doing a SD tune..
Yes but what matters is that it is set correctly (normally at 43.5) with no vacuum and tracks manifold pressure.Going to tighten all the hoses, lines, grounds just to double check. I have a AEM Fuel pressure regulator with a gauge so I’ll take a look at that? ( if that’s what you’re referencing to?) just gotta figure out what’s a normal reading lol.
