Why Response Time Matters
AEM’s patented X-Digital Technology minimizes the delay between changes in exhaust gas composition and sensor output, known as deadtime. This rapid response ensures your AFR readings accurately reflect real engine conditions, enabling cleaner, more consistent tuning. Faster response times reduce the risk of running unsafe air/fuel mixtures under high load or boost, protecting your engine and improving performance.
