The spacing was purposely set through extensive development to ensure that false positives from extended oil service intervals would not occur. The IMSG Sensor is a true Magnetic CHIP Detector, not developed to be as sensitive to typical ferromagnetic "fuzz" from normal engine wear that can cause a false positive.

The IMSG Jr. uses the same exact MCD Sensor, but a different interface and is a universally applicable system that does not integrate as factory in the Porsche dash, like the IMSG Sr. does (for cars pre 2005). The IMSG Jr. is now available.

LN Engineering now sells these units and we are only the manufacturers.

Here is a sample of the type of material the IMSG MCD is designed to detect.
