Hi, I'm a Speeduino newby in the UK. I've just assembled a v0.3.7 board and I'm slowly finding my way around TunerStudio on a Mac. I've successfully installed the firmware and the basic tune, and the gauges work with a SpeedySim. However, sometimes the rpm gauge suddenly drops off to zero and the LEDs stop blinking. I've tried re-installing the basic tune and that worked, but not on all occasions. Sometimes the rpm gauge would spontaneously spring back into life and the ignition and injection LEDs would come back on. The TPS gauge keeps working all the time. I wondered if it's Mac related, or maybe a hardware fault. I also have another issue, but I'm not sure if it's related. Grateful to hear if you have an idea what could cause this, thanks in advance.
