Problem with setting the maximum temperature limit on Fireflylite T9R with FFL909MX buck + fet

Now I have managed to solve the mystery of my T9R. It turns out that I followed the pattern of my TS30S PRO and for whatever reason, distance between the LED and the temperature sensor, thermal efficiency, etc., the behavior of both is very different. My TS30S PRO also has the thermal limit at 60 degrees and when dimming its luminosity, the body of the flashlight in its hottest area reaches 61-62 degrees and I have understood that this is the normal behavior in all flashlights. Today I have tested my T9R again in turbo mode and setting the thermal limit at 60 degrees, starting from an initial temperature measured with its sensor of 20 degrees, it has maintained the turbo for practically two minutes until the dimming occurred. The body of the flashlight marked about 50 degrees but when immediately checking with its own sensor its temperature marked 59 degrees. After a second of time it was already reading 57 and in a few seconds it dropped quickly, so if you forget to measure and 10 seconds pass, the temperature that the sensor will read will be several degrees lower and hence the confusion generated. The confusion also comes from insisting on measuring with an infrared thermometer on the hottest part of the outside of the body of the flashlight. I understand that this difference of almost 10 degrees between the sensor and the hottest part of the outside of the body of the flashlight is due to the good thermal efficiency that the flashlight shows and that it is able to dissipate heat in a very efficient way. So I assume that the flashlight behaves normally and does not have any manufacturing defects. Thank you all for your contribution and have a wonderful day

Good to hear that you solved your T9R mystery, congratulations!

On another note, thanks again for posting the printed manual, which (to me) seemed somewhat unclear about how to enter turbo. This has prompted me to visually clarify this diagram by myself. It used to look like this:

I understand that this may lead to the impression that you can press 2C (from On/Ramp or from Off), and immediately continue to turbo with another 2C from On/Ramp. This is only true for Anduril 1 turbo style (“Turbo”; after 2C from Off to ceiling, you can go on to turbo with another 2C, and 2C from On/Ramp will directly go to turbo), but this is a generic diagram for “vanilla” Anduril, and the “vanilla” default turbo style for Advanced UI is Anduril 2 turbo style (“Ceiling, or turbo if ramped up to ceiling first”). So now, the diagram looks like this:

To complete this turbo style visualization: there is also an exemplary model-specific diagram available for model number 0135, hank-emisar-2ch. The default setting for Advanced UI’s turbo style for this model number is Anduril 1 style (“Turbo”), so in this case, the turbo style looks like it did before, like this:

Hopefully, by now, not only your T9R mystery is solved, but also the Anduril turbo mystery. :grin:
