+# Chrysler NGC (untested)
+## Overview
+
+Decoder for 4-cylinder engines equipped with the Chrysler NGC pattern. Seems to be used on some Chrysler/Jeep/Dodge vehicles from 2002 onward.
+
+This decoder has only been tested on a simulator, please notify speeduino maintainers if you have success or issues with it.
+
+## Tuner Studio Configuration
+
+- **Trigger Pattern:** Chrysler NGC
+- **Trigger Angle:** 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).
+- **New ignition mode:** On is recommended as it gives a more accurate spark angle.
+
+## Trigger Signal
+
+This a 36+2-2 tooth wheel paired with a 7 tooth cam.
+
+The crank wheel has 2 normal LOW missing teeth where the opposite side has two HIGH missing teeth.
+
+The cam wheel teeth are mirrored. One side has a long HIGH tooth and the other has a long LOW tooth.
