AEM X-Series Wideband UEGO AFR Sensor Controller Gauge

Faster response times improve wideband feedback control, enabling safer, more powerful, and more accurate tuning. AEM’s X-Digital technology-equipped wideband controllers reduce dead time to improve your vehicle's performance through more precise AFR tuning. Dead time is the delay between a change in exhaust gas composition and its reporting by the O2 sensor. While exhaust flow can affect dead time, it is not the only factor; in many cases, the response time of the sensing element to the gas is the largest contributor to dead time. When tuning an engine using wideband AFR feedback control, dead time affects the observed data, meaning the data is reported for an operating state different from when the actual change occurred. In other words, adjustments made to base fuel settings may be applied in the wrong time frame. This is particularly dangerous for engines with high cylinder pressures or EFI systems that utilize feedback control.

Before You Order

〇Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.

〇Compatibility Check
Our entire product database is based on North American specification vehicles (USDM), so please verify compatibility with Japanese specification vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
We cannot accept returns due to incompatibility if you place an order without confirming compatibility beforehand.
Please note that even if products are sorted by selecting the year, make, and model in the tabs on our homepage, it does not necessarily guarantee that they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.

○Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually via email.

All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Note that all products are transported by air; they are never shipped by sea freight.

○Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength calculation documents or similar paperwork for these regulations. Therefore, all parts are sold for use on "circuits, private property, or off-road," and installation and use are at your own risk.

○Regarding Warranty
Please check the contents of your package immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or exchanges for damaged, defective, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
