# Wall Wetting Based Acceleration Compensation

## Wall Wetting (alpha version)

**Wall fueling model type**:*Basic (constants)*use the*Evaporation Time Constant*and*Added to Wall Coefficient*values for Beta and Tau respectively,*Advanced (tables)*uses the*Wall Wetting AE Evaporation Time*and*Wall Weeting AE Impact Fraction*tables to calculate the Beta and Tau values respectively.

### Basic

**Evaporation Time Constant / Tau**: Length of time in seconds the deposited wall fuel takes to dissipate after the start of acceleration.*wwaeTau***Added to Wall Coeff / beta**: Fractional representation of fuel settling on the intake/port walls. 0 = No fuel settling on port walls 1 = All the fuel settling on port walls. Setting this to 0 disables the wall wetting enrichment.*wwaeBeta*

### Advanced

#### Wall wetting AE evaporation time

Used to calculate the Tau value (*wwaeTau*) of wall-wetting function.

**Evap time vs. CLT**: Sets the base evaporation time based on CLT. Warmer engines will have a lower evaporation time.**Evap time vs. MAP**: Sets the multiplier of the base evaporation time based on MAP. Lower MAP values will have a lower multiplier (shorter evaporation time), higher MAP values will have a higher multiplier (longer evaporation time).

#### Wall wetting AE impact fraction

Used to calculate the Beta value (*wwaeBeta*) of wall-wetting function.

**Impact fraction vs. CLT**: Sets the base impact fraction based on CLT. Colder engines will have a higher impact fraction (more fuel sticks to the walls), warmer engines will have a lower fraction (more fuel sucked into the intake). Values range from 0 to 1.**Impact fraction vs. MAP**: Sets the multiplier of the base impact fraction based on MAP. Lower MAP values will have a lower multiplier (more fuel sucked into the intake, higher MAP values will have a higher multiplier (more fuel sticks to the walls).
