Alpha-n/Speed Density settings
- VE table control startegy:
To configure VE table with TPS or MAP.
- MAP Sensor Connection:
Choose if MAP hose is connected before or after throttle.
- After, MAP lower than barometric pressure will be ignored in fuel calculation.
- Before, MAP will be included in calculations.
- Ign+Lambda table Y axis:
To configure Ignition and Lambda table with TPS or MAP.
For Alpha-N with boost compensation, use kPa.
- Ign+Lambda Kpa use:
For Alpha-N with boost compensation on firmware >= 1.2.32 a new Y axis using calculated load is available which
smooths out the transitions when using ITB's VE(Alpha-N) and Turbo, normal users use KPA (or TPS)
- kPa, Kpa (or TPS depending on Hybrid MAP/TPS threshold) as Y axis on Ignition and Lambda table.
- Load, Calculated load (airflow) as Y axis on Ignition and Lambda table.
- Table lookup threshold:
With Alpha-N (TPS) control strategy and Ign+Lambda table Y axis = kPa, you can choose to use TPS on the lower range below this pressure threshold.
- 110 kPa: 0-100 in table Y-axis uses TPS, 110 and above uses kPa. 100-109 will use the same value as 100% TPS.
- 0 kPa: Use only kPa for ignition and lambda tables.
