please upload your tune/calibrations https://github.com/rusefi/rusefi/wiki/HOWTO-upload-tune

please upload a log showing working TPS if you move throttle manually without power https://github.com/rusefi/rusefi/wiki/HOWTO-upload-log

anything ETB on bench first suspect is power supply which is unable to produce enough amperage, sometimes 5A is needed. please provide a photo of your power supply

please try setting PID randomly something like https://rusefi.com/online/view.php?msq=1383&dialog=etbDialog or https://rusefi.com/online/view.php?msq=1254&dialog=etbDialog or just try settings from different not default tunes

please use youtube since yandex disk error

I will double check if instructions cover bias curve validation. Please set p=i=d=0 and move pedal, some vaguely reasonable movements expected from etb

C'mon, red blinking indicator clearly tells you that your TPS calibration is incorrect. Until you get TPS calibration right you are not in the position to control it reliably.

Kind of our fault - we have a mechanism to stop ETB in case of sporadic error like yours but it might be broken :( https://github.com/rusefi/rusefi/issues/5056
