THE BIG IDEA:
SenX Technology is a Michigan based company founded in 2002 to commercialize the use of piezoelectric materials in sensors. John Brock obtained US patent rights that have been implemented in SenX products that have been used in a number of applications where periodic pulses tell an important story.
WHY THIS IDEA IS BETTER THAN THE REST:
With FirstLook® engine diagnostic sensors, do five minute mechanical engine checks without touching a wrench! Many mechanical issues do not trigger a code. If the engine checks out and you do have a code, you can trust the OBD scanner; otherwise, your scanner will probably mislead you.
