Hello folks,
Some more weird issues with my car (I had an IAM issue a few weeks ago as well). I was driving along a few days ago and I hear my OFT trigger the alarm for high LTFT. I haven't had the chance to datalog yet, but it was going below -10% (my alarm trigger point) at low throttle low-RPM scenarios. Backing off the throttle at that point seemed to make the alarm stop, but it kept happening a few times.
This was in 3rd gear about 15-20% throttle at around 3000RPM. I believe it also happened again in 4th gear, but I'm not sure. This was yesterday, and I've been having the same issue during my morning commute today as well. I'm running the OFT Stage 1 tune with 94 octane.
I will attach datalogs in a few hours after I go home. Any idea what is causing this? I don't think its an exhaust issue since my LTFT is negative and seemingly gets worse with more throttle, and not the other way around. Plus my exhaust is completely stock. Only modification on the car is the tune and a K&N drop in filter. Car has about 36k KM on it so I can't imagine very many things are worn/degraded yet.
Thanks for any help

It happened twice on my commute back and both it happened almost immediately after I backed off about 50% throttle.
