  * @file    accel_enrichment.cpp
  * @brief   Acceleration enrichment calculator
  *
+ * In this file we have three strategies for acceleration/deceleration fuel correction
+ *
+ * 1) MAP rate-of-change correction
+ * 2) TPS rate-of-change correction
+ * 3) fuel film/wal wetting correction
+ *   AWC Added to Wall Coefficient, %
+ *   AWA Added to Wall Amount
+ *   SOC Sucked Off wall Coefficient, %
+ *   SOA Sucked Off wall amount
+ *   WF  current on-Wall Fuel amount
