In the following description of the VDO inputs the order will be input 2, 3, 1. In this
way we are using the same order as in the TPS 300 software.
VDO sensors are noise sensitive; therefore we recommend using 2 wire sensors.
There are three VDO inputs in the unit. The inputs have different functions due to the fact that the
hardware design is able to cover several VDO types.
All VDO inputs have a general accuracy of 2%.
VDO input 1:
VDO input 2:
VDO input 3:

VDO input 1, fuel level: type 1 and 2 curves are linear.
Type 3 is fully configurable with 8 points in the input range 0-180 and 0-100%.
