IAC temp correction is usually a transition from just off a period of idle. Pulling away from a stop sign. IAC temp change rate is much higher. This table adjustment is rare.


Vtune3 does address Spark Temp Correction along with the main spark table. I look at it as tuning the engine for best performance available for the condition over taking performance away. Before we tuned for worse case scenario, and it was good enough for all.
