I ch immediately saw that it simulated the outside temperature by at least 20°. So it has 22° air temperature, so it shows me at the tester of the air temperature meter only 0°. Everything else was unchanged! My question: what changes it in the injection when the temperature is simulated to 0° but it has real 22°? That would really surprise me.,…
