Re: Bosch LSU4.9 on S8

Ah, yes: makes sense.
The LSU4.9 datasheet is VERY particular with the do's and don't regarding the heater. I have implemented proper heater control on my new I/O expander and, I think, Pat has now done the same on the GP+. The NTK is not fussy: bung some PWM volts on it and be happy!
But Bosch do tend to be very cautious with their datasheets.
As an engineer, I would not recommend basic heater control on the LSU4.9...but if people have being doing it for years then who am I to criticise!
