# Chrysler NGC (untested)
|
|
## Overview
|
|
|
|
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.
|
|
|
|
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:**
|
|
- **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).
|
|
- **New ignition mode:** On is recommended as it gives a more accurate spark angle.
|
|
|
|
## Trigger Signal
|
|
|
|
All versions use the same 36+2-2 crank wheel but the 6 and 8-cyl has TDC 180 degrees away from the 4-cyl version.
|
|
The crank wheel has 2 normal LOW missing teeth where the opposite side has two HIGH missing teeth.
|
|
|
|
### 4-cylinder
|
|
|
|
The 4-cyl trigger pattern uses a 7 tooth cam. The cam wheel teeth are mirrored. One side has a long HIGH tooth and the other has a long LOW tooth.
|
|
|
|
|
|
|
|
### 6 and 8-cylinder
|
|
|
|
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.
