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). +- **Trigger Angle:** + - **4-cylinder:** Should be set to 30 +- a few degrees for a stock setup.
