+# Temperature based timing changes
+Changes in Inlet Air Temperature (IAT), in particular significant increases whilst under boost, can require ignition timing to be pulled. The IAT retard settings allow for this timing adjustment
+
+## Example
+Exact settings will be engine dependant, but pulling of ignition timing beyond 100\*C is a common scenario.
