Just yesterday I happened to note that log from my WOT (done yesterday as well) is having a non zero value for LTFT_InUse. This is weird as I have applied the "Closed Loop - LT Trim Control" patch more than a year back and logs from then showed that LTFT_InUse is returning zero as it switches to LTFT_High during WOT.

Using EvoScan, I logged Fuel Trim High (LTFT) and true enough it's returning me a value of 1.56.
Tried flashing back one of my old ROM from last year but it didn't help so I am thinking it not due to the changes I have made recently.

Anyone experiencing this?

 

Yea mine happened recently too. I got a .96~ value in ltft_high.

I had the following in the trim control table:
mid -> high: 300.00Hz
high -> mid: 293.75Hz

I lowered each two steps and still got a value in ltft_high, so I lowered them another two steps to:
mid -> high: 268.75Hz
high -> mid: 262.50Hz

Haven't driven enough to bother checking ltft_high yet, I will report back today or tomorrow.

I think with certain mivec, etc, the stock turbo still spooled fast enough to hit those Hz while in closed loop? Not sure, maybe someone can correct me on this.

 

Yep, you hit closed loop at the high trim's settings.

Fix the ranges or the Open Loop Load tables and reset your trims.
