60-2 (58x) THE TRUTH
First, the person(s) who have stated this to you are
LIARS, maybe just STUPID.
I will state the a "VR" sensor could have a problem over 14,000 RPM due to sensor design.
That requirement would be switched to the 36-x target.
The LS-7 (GRAY) hall sensor (60-2 target) has been tested to over 12,000 RPM with no problems.
Those EMS that can not do the decode are just plain JUNK.
ASK yourself why GM uses the 60-2 (58x) are they dumb ?
NO they are VERY sharp, they look at the tooth acceleration.
Now, I like John M., though to do the decode correctly
the processor needs speed in the decode area.
Most (OEM's) state a 100mhz frequency is required is the decode area, ours is 160 mhz.
With that my EMS can easily run over 25,000 RPM.
When the 60-2 is decoded CORRECTLY we see the tooth acceleration that is present durning
combustion/engine RPM increase/decrease.
That information is used to "predict" the spark instant.
That information is used to "inspect" combustion quality.
Remember, I was part of the team who worked with Alex Long, the INVENTOR of DIS with
"missing tooth decode" using the 60-2, 36-1 targets.
