When tuning an engine on an inertia dyno using wideband AFR feedback control, dead time affects the data you see because it is reported at a different operating point than where it actually occurred. If the dead time is long, base fuel changes will likely be applied to the incorrect location. This can be particularly dangerous for high-compression engines, high-boost forced induction vehicles, and EFI systems that utilize feedback control for auto-tuning. Reducing dead time improves wideband feedback control, enabling safer, more powerful, and more accurate tuning. Wideband controllers featuring AEM's X-Series digital technology reduce dead time and improve your vehicle's performance through more accurate AFR tuning.


Before Ordering

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 there will be no additional charges beyond the total amount paid at checkout.

Checking Compatibility
All product databases are based on North American vehicles (USDM), so please verify compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure whether a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to look it up for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are filtered by selecting the year, manufacturer, and model using the tabs on our top page, it does not necessarily guarantee that they will fit Japanese models 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 fees are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping fee and the actual shipping cost. In such cases, we will contact you individually via email.

Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm the delivery date. Please note that all products are transported by air; they are never shipped by sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products handled by our company are basically designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength calculation reports for the Japanese inspection system. Therefore, all parts are sold for use on "circuits, private land, or off-road," and installation and use are at your own risk.

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