How Close to 1, Is yout LTFT?

[BL92]

Mine are sitting around .93 / .91 after 1000 Miles from reset of adaptions

running MPG 20.6

When time permits, and next time your INPA, Can you kindly post your LTFT to compare to each other and see who is actually close to 1 etc

You're not running a CSL airbox conversion are you?

Negative, All stock

I was just being nosey, and wanted to know what everyone else's LTFT are to compare

Here's where I'm at currently, 1.01 and 1.00. I've done some mods over the past few months, so it's not a direct comparison but it's a data point. I installed Megan headers and deleted the secondary air pump about 1000 miles ago, and disabled the rear O2s, EGT, and SAP at the time using the binary tool. About 500 miles ago I added the Evolve remap through the binary tool. Then about 150 miles ago I installed the Eventuri intake.

I thought I had initial screenshots of my values before making any changes, but I couldn't locate them. That being said, I'm certain that they were very close to 1 before any changes, and I'm pretty sure they were both within a couple of hundredths (between .98 and 1.02).

Either you just reset adaptations (even though cyl ign # are showing adaptation values), or Evolve did some craptastic Alpha-N tuning there for all the lower values to be stuck at 0 and 1.

Dangerous, your fuel trims are disabled !!

Are the data in the red circle precat O2 sensors? If they are then the engine was not running in closed loop, as the normal O2 data should be switching between 0.2 to 0.8v instead of sitting perfectly in the middle 0.45v

The post-cat sensors are also not working. Engine was still too cold?

Isn't the point of this screenshot just to show the adaption values (bottom two rows)? That's the context I get from this post. Not sure what the O2 sensors were doing at the time OP took the screenshot is really relevant here? Unless I'm missing something?

LTFT data are valid only if and only if DME runs in closed loop with precat O2 working.
