Hi, can not download your file. I am new in the forum. I have made the Tiny_Sweeper but it does not work. I had download the tiny sweeper project form www.tmw.netlook.pl. With an oscilloscope I check the output and it goes form 20Khz to 20Hz as it should be. It takes 1 minute and 28 seconds to complete. I have tested on Renault Safir2 55pin and it does not work. On which ECU have you test it ?
