ECU - 4.2L

The modern Electronic Control Unit (ECU) manages a variety of engine functions including ignition timing, fuel injection, and air to fuel ratios. Tuning the ECU within the design parameters of the 4.2L power plant allows STaSIS to provide reliable power gains without sacrificing longevity. With significant gains in low end out put Signature Series software is the no compromise solution for increased engine performance.

Stock configuration of the S5's 4.2L power plant is rated at 340hp/302lbft. Signature Series software pushes out put to 360hp/320lbft when paired with STaSIS exhaust components. The numbers speak for themselves, but the exhilaration provided by improved low end power will turn your daily driver into a race-bred sleeper.
