Depends on which firmware. In most cases though, you’ll at least need to set the LVP threshold to match the physical driver it’s running on. Those values change from one model to another, between brands, etc.
Thanks to DB Custom (and other posters that I can’t locate) for tips on improving my bypass:
How to turn of turbo timer ?
Turning off the turbo timer on the BLF-A6 requires flashing modded code onto the driver. The code is available, but it needs about $10 or $20 worth of other hardware for the flashing process.
I have the Astrolux version and it recently gets a spring bypass upgrade.
It gets hot much faster now and gets uncomfortably hot after putting usage.
Is that normal it there’s something I’m missing?
So… it sounds like the spring bypass worked. :+1:
Hi TK, thanks for the explanation. Love your work :+1:
Looking to do the Spring mod but notice something odd with my tail cap switch… It has the main spring as it should do but the is a smaller spring made if thinner wire loose (see attached image)Microsoft OneDrive - Access files anywhere. Create docs with free Office Online.
Anyone know why or what it’s there for
The inner spring is for lower resistance and higher amps / lumens. But it should be soldered to the board of cause.
oh eer urm
so it should be there to do the spring mod then
what would you suggest I do to correct this?
If you do the spring mod (bypass with a wire), the inner spring is not needed, it will not do much. You can just remove it if it is loose already.
Cool thats great…
Question….Is it possible to do a TEMP mod to check and see if I really need it?
What is soldered can be unsoldered no problem.
Can anyone reminds me what the firmware that came with the A6 called? Bistro?
I believe it’s just called BLF A6 :
Sometimes the answer is in plain sight. 
(the code was written specifically for that project, so I named it after the project)
I still think for that specific light, your firmware is just about perfect. If that light is putting out 1500 or 1600 lumens and is triggered by accident in your pocket, 30 seconds step is very much appreciated. Fun fact: my mother in-law saw my a6 sitting on the coffee table and turned it on and didn’t see any light so clicked it on off, then looked into the end of it and clicked it again. That was honestly a slow motion train wreck that I had no intention of stopping. Priceless!!
Thanks TK, I love Bistro but the blf a6 and associated mother in-law stunning will forever hold a place in my hall of fame!
As it turns out, the mother-in-law stunning is a pretty well-documented part of that light.
thanks.
lool so true, if i remembered correctly BLF A6 uses attiny13 right so bistro should fit right in?
also got convoy S+ can i put BLF A6/Bistro on in too, i dont like the 3 modes on this flashlight.
I did that to my sister with an Astrolux S41S. I was wearing it on my belt, she was curious about it, so I handed it over. Never even thought about what would happen next.

Once and once only. I simply don’t let anyone touch my A6-class lights now.
After all, I have plenty of nice, safe BLF-348s and sub-500 lumen Convoy S2+ lights for them to play with instead
