The most aggressive level,...
The most aggressive level, known as "SP3," quickly brought our tach needle to 5,100 rpm. Our STI's rpm quickly revved to the 5,000-plus rpm level with minimal pressure on the throttle accelerator.
Sport 2
The "SP2" graph shows a significant change in throttle compared to a stock throttle. The "SP2" setting increases the throttle ratio twice the rate of the SP1 setting, designed for sport driving and circuit use. From 0 to 100 percent, throttle characteristics through acceleration are increased dramatically.
Sport 3
Blitz engineers have labeled the most aggressive setting, known as "SP3," for extreme sport and circuit use. The throttle is opened at four times the standard accelerator position. Graphs show at 50 percent acceleration, the throttle at full engagement at 100 percent. Driving in this mode on the local streets and highways in traffic can be a daunting task since the car will have a tendency to lunge forward when clutching due to the rapid increase in rpm and throttle. This setting is ideal for track usage or quarter-mile sessions.

Here is the Blitz harness used when installing the controller on the STI. Blitz also has a reverse cancel harness sold separately that many of its competitors don't implement into their units. The reverse harness prevents the Blitz unit from working while in reverse gear. Revving to 5,000 rpm in reverse by mistake while parking in the garage or parallel parking is quite a task.
The Blitz throttle controller...
The Blitz throttle controller is simplistic in design and easy to install and program, allowing the most novice of end users to get their car up and running within minutes.

Economy
Using a graph to show the differences between the factory throttle position and the Blitz unit tested on all four modes, the X-axis represents accelerator while the Y-axis represents throttle. The "Eco" mode is used primarily to increase bottom end response. The graphs show the blue line indicating the Blitz controller has increased throttle till reaching the 30 percent marker where it automatically goes back to the factory settings in terms of throttle and acceleration. This is designed primarily for fuel economy/consumption to reduce the driver having to continually press on the throttle at different rates.
Sport 1
Blitz claims the "SP1" mode is a balance between fuel economy and throttle response. Throttle is opened greater at lower revs compared to factory settings and slightly higher than the "Eco" mode, providing increased acceleration at lower rpm and a slight variance in higher rpm.
Sport 2
The "SP2" graph shows a significant change in throttle compared to a stock throttle. The "SP2" setting increases the throttle ratio twice the rate of the SP1 setting, designed for sport driving and circuit use. From 0 to 100 percent, throttle characteristics through acceleration are increased dramatically.
