There are many different tools that can be used for measurement, but the degree of accuracy is dependent upon the tool. For example, a ruler can measure distance with a good degree of accuracy, but for a more precise measurement a caliper should be used. The difference between a brass pressure sensor and a stainless steel pressure sensor is similar if we think about it in these terms:

• High-quality sealed sensor housings are virtually impervious to automotive fluids (360-degree welded wetted area)
• Stainless-steel sensors accurate to within 1% of full scale (pressure sensors)
• Includes 1/8" NPT to -4 AN adapter included
• Connector and pins included

Gauge style pressure sensors reference pressure above atmospheric pressure. When exposed to atmospheric pressure, gauge style pressure sensors will read 0 psig. Gauge style pressure sensors are commonly used for oil pressure, fuel pressure, brake pressure, nitrous pressure etc.Which Pressure Sensor is right for you?There are many different tools that can be used for measurement, but the degree of accuracy is dependent upon the tool.

AEM's RTD-Type Temperature Sensor (PN 30-2052) is packed with features that deliver consistent measurement and long life. This AEM EGT Sensor features a closed-tip design that lasts longer than the previous generation's perforated tip design and the tip is smaller for less intrusion-and less restriction. Inconel-tubing protects the wiring, which is terminated with a high-quality DTM-style 2-pin connector. The sensor reads a temperature range of -40 to 1,560 degrees F (-40 to 850 degrees C), and its thin-film platinum element provides a high degree of accuracy (+/- 0.9% from 536 to 1,560 degrees F). Our RTD-Type Sensor features a 90-degree bend at the sensor tip for easier installation in tight spaces, and it includes a weld-in sensor bung with machined M14x1.5 threads.

Accurate AFR data is critical when tuning an engine. Running rich (very low air/fuel ratio, excessive fuel) can cause a loss in power, while running too lean (very high air/fuel ratio, not enough fuel) may result in serious engine damage. Using a wideband air/fuel controller during the tuning process allows you to monitor AFR and adjust tuning parameters to optimize them for maximum power and efficiency. AEM has a comprehensive line of highly accurate, reliable wideband air/fuel controllers that can help ensure your vehicle is optimally tuned.

When tuning an engine using wideband AFR feedback control on an inertia dyno, deadtime affects the data you are looking at because it is reported in a different operating location than when it actually occurred. This means with long deadtimes, whatever changes you make to the base fueling will likely be in the wrong location. This can be particularly dangerous to high compression and high-boost forced induction vehicles, and EFI systems that use feedback control to auto tune.Reducing deadtime improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM's Wideband Controllers with X-Series digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning.

Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM's Wideband Controllers with X-Digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning. Deadtime is the delay between when exhaust gas composition changes and when that change is reported by the O2 sensor. While flow of exhaust gases can affect deadtime, it is not the only source. Often, the sensing element’s response to the gas is the largest contributor to deadtime.When tuning an engine using wideband AFR feedback control, deadtime affects the data you are looking at because it is reported in a different operating location than when it occurred. This means whatever changes you make to the base fueling will likely be in the wrong timeframe. This can be particularly dangerous to high cylinder pressure applications, and EFI systems that use feedback control.
