Is it tripping the ring and string or the EQ Box?

I know some of the boxes have sensitivity settings and I have had luck playing with those.

If it's the string, tighten that spring and check your clearance, sometimes a little bounce or a little wind will set those off.

As for it not recovering when on earthquake mode, I would check your software settings. I seem to recall SES-02 and a few other options being a problem.

If you can look at the software in a similar car, just make it the same
