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.","brand":"AEM Electronics","offers":[{"title":"Default Title","offer_id":51748844831041,"sku":"FDDP_30-0310","price":293.39,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/1289\/6321\/files\/30-0310-FDDP.jpg?v=1779316068"},{"product_id":"x-series-wideband-uego-afr-gauge-kit-x-digital-technology-8-501-to-181-afr-scale-aem-electronics-30-0300","title":"8.50:1 to 18:1 AFR Scale - Black Bezel - Black Face","description":"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.","brand":"AEM Electronics","offers":[{"title":"Default Title","offer_id":51748849320257,"sku":"FDDP_30-0300","price":304.91,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/1289\/6321\/files\/30-0300_9-FDDP.jpg?v=1779316254"},{"product_id":"classic-digital-wideband-afr-gauge-kit-the-original-wideband-air-fuel-ratio-gauge-w-bosch-lsu-4-9-sensor-aem-electronics-30-4110","title":"LSU 4.9 Sensor - Interchangeable bezels and face included","description":"Our World-famous Wideband O2 air\/fuel ratio UEGO gauge features a digital LED display and sweeping LED 'needle' that changes colors as AFR changes from rich to lean. A 52mm (2-1\/16\") gauge housing ensures that it will fit in most gauge pods and can be remotely mounted virtually anywhere. All AEM digital gauges feature a 0-5v analog output for use with data loggers and almost any engine management system. Each gauge comes with black and silver bezels and black and white faceplates for multiple color combinations and a custom look (a black Lambda faceplate and black and white Air\/Fuel Ratio faceplates).The UEGO sensor gives the controller its speed and accuracy. The 4.9 LSU sensor used in the 30-4110 AEM Wideband UEGO AFR Controller Gauge has a faster light-off time and draws less current than the 4.2 LSU sensor used with AEM's 30-4100 Wideband UEGO Controller Gauge, which will be superseded to the 30-4110 gauge in August 2014. The 4.9 LSU sensor features the same fuel compatibility as the 4.2 LSU and NEVER requires free-air calibration when used with AEM's 30-4110 Wideband UEGO AFR Gauge. The 30-4110's 4.9 LSU sensor uses a different connector than the connector used with the 4.2 LSU sensors included with the original 30-4100 gauge controller. The sensors are not interchangeable between the two gauge controllers in any way, including changing connectors on the gauges.The Wideband O2 air\/fuel ratio UEGO gauge is a must if you want to maximize your engine's power and safety. When tuning an engine, accurate air\/fuel ratio data is critical because running with too rich of an AFR can cause a loss of power, and running a lean AFR can result in serious engine damage. AEM's digital Wideband AFR UEGO gauge can quickly alert you to even a .1 change in air\/fuel ratio and provide enough time to shut down an engine before damage occurs.","brand":"AEM Electronics","offers":[{"title":"Default Title","offer_id":51748853547329,"sku":"FDDP_30-4110","price":278.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/1289\/6321\/files\/30-4110_0-FDDP.jpg?v=1779316609"},{"product_id":"x-series-obdii-wideband-afr-gauge-kit-obdii-connectivity-on-08-up-vehicles-only-aem-electronics-30-0334","title":"AEM X-Series OBDII Wideband AFR Gauge Kit","description":"WHY RESPONSE TIME MATTERS - Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune.
