Hi There! I tried to make a DIY circuit to convert the modern ECU 5v pulse of RPM for my VW GOLF-2 which upgraded to GOLF-4 engine to the original 12v analog tachometer with the most known circuit of a relay coil, resistor and couple of diodes but it failed after 2000 RPM, it drops to zero when...

Consider a embedded system such as Electro Hydraulic Power Steering ECU mounted in a heavy duty commercial truck. When key switch is turned off, the ECU should executes very limited functionality in sleep. It is not suppose to log faults in sleep mode?

Hello everyone, I'm currently working on a Hybrid vehicle project called REEV (Range Extended Electric Vehicle) for a competition organized by SAE India. The VCU in our car is connected to critical components like the battery, motor, generator, and various sensors. I need to acquire data such...

Please consider Electro Hydraulic Power Steering (EHPS) System installed in a commercial truck. It has dual motors and dual pumps and dual pump Electronic Control Units (ECUs). These pump ECUs communicate with other ECU over public J1939 network. Embedded steering software executes in pump...

Hello Everyone, my name is Fredrik. I am new to this forum, and I want to ask you guys about a project I am working on atm. I plan on making a test tool (or voltage sniffer) for monitoring voltage on multiple signals at once. The ECU I will be monitoring has up to 110 different inputs. My first...

Hi everyone, I don't know why but I'm having a tough time decoding CAN Bus data frames, even after looking at many sources showing bit field diagrams of how the data is supposed to be structured. Background on project/goal My main goal is to connect directly to an electronic turbo actuator...
