2.3.2 Inputs
10 / 76
The analogue inputs are divided in different hardware classes and qualities.
3.01 kOhm pull-ups are fixed or switchable designed to assist passive sensor elements like
NTC temperature sensors or to change to active signal inputs.
Some of the inputs assist only active sensors and offer no pull-up.
To improve measurement tasks, angle related measurements are an option for some in-
puts, mainly used for engine related leading signals.
The connection between function and related input is free selectable, beside electronic
throttle functionalities.
All linearization mappings are open to the customer, some signals offer online modes to
calibrate gain and offset.
Digital inputs for speed measuring offer divers hardware options to connect inductive- or
digital speed sensors.
Please respect: for camshaft- or wheel speed signals Hall-effect or DF11 sensors have to
be used and for wide range Lambda measurement and control the Lambda sensor Bosch
LSU 4.9 has to be used.
