PMU16-DL Power Management Unit (with Data Logging by ECUMaster)
Race cars are equipped with advanced engine management systems, anti-lock braking systems, paddle shifts, data loggers, radios, electric pumps, fans, and lights. Every component must be controlled at the correct moment, and each requires circuit protection to prevent damage or fire. Traditionally, fuses and relays have served these purposes, but they have had many drawbacks, such as complex wiring, sensitivity to vibration and temperature, and difficulty in diagnosis.
All these issues can be solved by using an intelligent Power Management Unit (PMU). Our newly developed PMU unit is at the forefront of technology. It provides 16 high-current outputs (multiple units can be used if more outputs are needed).
One of the main advantages of the PMU is its continuous current sensing and self-resetting capability when the current exceeds a defined level. All output states, voltage, and current information can be logged and sent to a dash display via CAN bus, notifying the driver of potential issues. An additional benefit of the PMU system is the ability to define the logic that controls the outputs. This is done using data from analog input channels or CAN bus data, and arithmetic operations can be defined for each channel.
The PMU is also equipped with LED indicators showing the status of each output. Using a CAN bus keypad or steering wheel switch, all wiring can be significantly simplified and lightened. Two unique features are the built-in accelerometer and gyro for logging, as well as an "inertia switch" for use in the event of an accident.
The PMU is assembled in accordance with IPC-S-815A standards to ensure product reliability. The device is manufactured on an automated assembly line with optical inspection and automated testing (including burn-in). The PCB material and design, special surface coating, and IP65 enclosure guarantee reliability in the harshest environments. Carefully selected components allow for continuous and reliable operation over a very wide temperature range (AECQ-100 GRADE 1 (-40 to 125°C)).

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 you will not be charged any additional fees beyond the total amount paid at checkout.
〇Compatibility Check
All product databases are based on North American vehicles (USDM), so please check the compatibility with Japanese vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure if the listed product is compatible with your vehicle. Our support team will investigate for you.)
If you order without checking compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not necessarily mean they are compatible with Japanese models 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 fees are paid at the time of payment. 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 cost and the actual shipping cost. In such cases, we will contact you individually by email.
Basically, 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 check the delivery time. Note that all products are transported by air; they are not shipped by sea.
○ Regarding Japanese Vehicle Inspection Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation sheets or similar documents for that purpose. 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. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. Please understand that we will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or products different from what you ordered. Please note that for products sold through us, warranty support will be handled "only through us." We do not provide support through other companies or distributors located in Japan.
