Decoder for 4, 6 and 8-cylinder engines equipped with the Chrysler NGC pattern. Seems to be used on some Chrysler/Jeep/Dodge vehicles from 2002 onward.
- **4-cylinder:** Should be set to 30 +- a few degrees for a stock setup. If both crank and cam sensors have reversed polarity -330 should work (for sequential).
- **6 and 8-cylinder:** Should be set to 210 +- a few degrees for a stock setup. If both crank and cam sensors have reversed polarity -150 should work (for sequential).
The 6 and 8-cyl cams are different but function in the same way. The position can be determined when knowing the number of teeth in two adjacent groups of teeth.
