The resistors are used to reduce the voltage going into the MAX chip, you need to set those so you get a reasonable voltage at cranking speeds, 0.5V or more, without pushing too much current into the MAX at higher RPM.

In this module there is 2 resistors holes empty, available to install, anyone have some inside about that?The MAX chip wouldn't be my preferred option, it will time out at low speed and be vulnerable to noise causing spurious triggering. The LM1815 or a discrete circuit would be more reliable.
