SI Drive Controller
For turbocharged Subaru vehicles with SI Drive
SI Drive is a function equipped on some Subaru sports models.The driving characteristic can be changed to suit the driver’s preferences. Factory stock SI-Drive control is based on accelerator position, and based on that information, the ECU controls the throttle valve opening and stock boost control solenoid valve to change the driving characteristics.There are some differences between vehicle types, but the basic idea is the same.
The standard SI drve allows the driver to choose from the following 3 modes
1: Intelligent mode - the fuel-conservative mode
2: Sports - normal mode
3: Sport sharp - the most agressive mode
Blitz SI Drive controller is a unique product which multiplies the 3 stock control modes with 4 settings, giving a total of 12 possible settings, by utilizing the factory stock boost control solenoid.
The 4 channels allow user adjustable boost pressure settings and in its lowest setting ie Off, the fuel consumption is better than the stock "I mode"
Channel 1, ECO1 - Improved fuel economy with smooth feeling
Channel 2, ECO2, - Slight improvement of fuel consumption over the normal mode.
Channel 3, MID, - Sports mode with slightly higher performance over normal mode.The most similar mode to normal setting.
Channel 4, SPL - The highest boost, the most aggressive mode.
Blitz SI Drive Controller also features
Easy, straight-forward plug-in (However, pressure hose for boost control is required to be installed)
Built-in Boost meter function (with warning/peak hold function)
