Typical results of K-Star model KST-VR (mapped ignition timing only) on a 911 SC. The graphs below represent ignition being mapped to allow the engine to run on 95 octane fuel without pinking and power loss. Not unusually, there has been a power increase. Fitting model KS3-VR (ignition and fuel mapping) would produce a larger power increase (10-12bhp approx). The throttle response in both cases becomes smoother and more crisp. Where converting to 95 octane unleaded is not required, K-Star may also be used simply to tune for maximum power and torque output.
