Default ltrim question

This morning with my cutout capped I logged my drive to work. Last night I adjusted my IFR table down to 90% of the stock settings and the average Ltims of 645 records was -3.03696 and -2.12019 (B1 B2). Is that TOO negative? I'm being told that I want my ltrims as close to 0 as possible. I could have sworn I read somewhere in here that the target range is -2 to -8.

Give the car a little more learn time so the LTFT will settle out. A day or two of driving, 100 miles, etc. But they seem to be good. Most set there LTFT's between -8 to 0.

I've changed the IFR to 92% instead of 90%, which brought them closer to 0.
-1.17 and -.48 is the average out of 650 records.

I've heard from some local guys that you want your ltrims as close to 0 as possible at all times. However I'm reading that you want them in the -2 to
-8 range within fuel cells 6-14. They should read 0 at WOT.

Mine are at 0 at WOT, and in the -3 to -5 range within the fuel cells 6-14, and an overall average of -1.1 and -.8...at least that was my most recent log.

As long as they are being compensated, it doesn't really matter. I like mine slightly negative, so it STAYS that way with varying humidity and temparature. Dead-on zero makes me think you will sometimes run slightly positive with weather variances.

Truely, you don't want just the average below 0, but you really want 3 & 7-14 LTFT cells bellow 0. That is what makes for 0 @ WOT, and stable fueling @ WOT.
