Note on how to change the freq. (by Kent):

To change the freq. go to the terminal for COUNTING HOUSE ROC23 (hatsv7)

change FROM HIGH TO LOW duty factor:
-type "bmw_steps_per_pause=2400", then type return;
-then check the freq by typing "bmw_steps_per_pause" and return;


change FROM LOW TO HIGH duty factor:
-type "bmw_steps_per_pause=167", then type return;
-then check the freq by typing "bmw_steps_per_pause" and return;

Note:
1/ smaller number is for high freq., larger number is for low freq.;
2/ low freq. is for normal production run;
3/ in hac terminal, "Ctrl+H" = backspace.
