Hello, I have such a problem, I installed the gas installation for my car (STAG 200) I want to adjust it myself (after installing it was regulated under warranty, the temperature of switching to gas was raised to 43 degrees because there was a tug after switching) I have a USB cable, I have left from the old installation. I installed the program from the manufacturer's website and the existing usb / R232 driver there, but unfortunately I can't connect to the gas controller, it shows the message "no gas controller"
