Gotta question looking for a simple answer.
When data logging using hpt I’m having erratic data readings. Like rail psi jumps to 400,000 etc.
I’ve got an issue in my communication wires somewhere.
has anyone wired in a simplified obd to flash and data log ?
What are the colors and pin outs of wires used?
