Info from the website below. User instructions and advanced user guide available.
NOTE: This is the original edition of the controller so the boost adjustment is separated into low boost 1-9 and high boost 1-9 (functionally 1-18). The newer unit has been simplified with a single boost adjustment range of settings 1-9.
|This version utilises the same features as the SPS1 and SPS2 with the added benefit of having variable boost and timing control.|
This functionality allows the user to adjust the car to varying degrees of performance by changing the boost pressures from the turbo. It also allows the user to use any grade of fuel at any time without the worry of damage to the engine. It also can be adjusted to take full advantage of race fuel or octane boosters that are typically out of the range of any performance software. All safety mechanisms and routines are left intact to prevent the user from setting the engine to operate outside of the safety limits.
The SPS 3 device allows the user to change the boost and timing of the vehicle. Some people wanted only 1 BAR programs for reliability and economy while others wanted 1.4 BAR for power. This gives the user the ability to select the desired boost level for what ever they are doing, be it a track day or a long trip. The adjustable timing allows the user to maximize power by adding or removing engine ignition timing. Some people like to use octane boosters for track days and this will allow the user to add more timing to fully utilize the added octane. While for the drive back they may want to fill tank with standard grade petrol to save money. This also allows the user to remove timing to provide a smooth and safe performance level with standard grade fuel.
