This Open Hardware Electronics is a direct fit and direct replacement of the factory hardware electronics found on Bosch ETBs and factory electronics of the car. It has the simplest electronics and it uses 2 hall sensors that output a PWM analog +5V DC signal.

This PCB upgrade solves, definitely, the annoying wear issue commonly found on the factory-original sensor of this ETB that makes your car run poorly.

For DIY fans, this PCB is compatible with any open-source ECU such as Speeduino and many others. If you buy only the assembled PCB, before running the engine of the car, requires programming using the PROG connector on the PCB to match the sensor specifications of the vehicle where it is going to be installed.
