I’m currently in the process of starting my Speeduino journey for a Ford 302. I notice that, when I upload firmware from speedyloader that tunerstudio initially detected my elegoo board, but after loading the base tune I cannot connect to tunerstudio. When I try to detect the firmware on the board it detects the elegoo board but labels it “spe” and states it does not recognize the firmware. Manually confirming the firmware results in no connection. I suspect this has a connection to the known ch304 chip issue.
While trying to compile v202207.1 firmware in the arduino ide, compilation hanged on “Timer.h” “no such file”. Rolling the timer library back to 1.5 corrects the compiler error and loads to the board. It did not correct the connection to tunerstudio.
