The timings above are adjusted for 9000us/4500us, with a tolerance of 281,250us.
You're changing the pulse tolerance to 1125us for pulse, and 562,5us for space.
I double-checked: this shouldn't interfere with the other decoders, so it could
be possible to apply it, without causing regressions.
I'll apply it.
Regards,
Mauro
