AEM's legendary Digital Wideband O2 AFR UEGO Gauge combines a wideband UEGO air/fuel ratio (AFR) controller with a gauge in one unit. It combines high precision, speed, and control, and features an easy-to-read digital LED display and a sweeping LED "needle" that changes color as the AFR moves from rich to lean. Note: The 30-4100 Wideband UEGO Gauge Controller, which uses a 4.2 LSU sensor, transitioned to the 30-4110 Wideband UEGO Gauge Controller, which uses a 4.9 LSU sensor, in August 2014. After this change, the 30-4100 instructions remain available under the Instructions tab. What is a Wideband UEGO Air/Fuel Ratio Controller? AEM’s Wideband UEGO (Universal Exhaust Gas Oxygen sensor, pronounced "you-way-go") controller is a high-performance, cost-effective tuning tool that allows you to accurately monitor your engine's air/fuel ratio (AFR). Why use a Wideband Air/Fuel Ratio Controller? Accurate AFR data is essential for engine tuning. Running rich (low air/fuel ratio, too much fuel) can cause a loss in power, while running too lean (high air/fuel ratio, not enough fuel) can lead to serious engine damage. Using a wideband air/fuel ratio controller while tuning allows you to adjust tuning parameters for optimal power and efficiency while monitoring your AFR. AEM offers a wide range of highly accurate and reliable wideband air/fuel ratio controllers to support the optimal tuning of your vehicle. What is Free Air Calibration? Some competitors require frequent free air calibration. This is a process where the sensor must be removed from the bung and waved in the air while still connected to the controller to measure the oxygen level in the atmosphere. AEM's wideband controllers use a 4.9 LSU sensor, which is individually laboratory-calibrated, so free air calibration is not required.


Before Ordering

〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred during importation on your behalf, so there will be no additional charges beyond the total amount paid at checkout.

〇Checking Compatibility
Our product database is primarily based on North American vehicles (USDM), so please check whether the product is compatible with your Japanese vehicle (JDM) before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if a product is sorted by selecting the year, manufacturer, and vehicle model using the tabs on our homepage, it does not necessarily mean it will fit a Japanese model vehicle without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.

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

In principle, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with enough time to spare. If you are in a hurry, please contact us in advance to confirm the delivery date. 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 fundamentally designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection system," and we cannot provide strength evaluation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.

○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be delivery damage to the packing boxes or products. Please understand that we will only provide returns, refunds, or replacements for products with delivery damage, defective items, or items that differ from your order if you contact us within 7 days of receipt. Please note that for products sold through us, warranty-related support will be handled "only through us." We do not provide support through other companies or distributors located within Japan.
