Decades ago, the critical electronic components in a race car were the ignition coil and points. Race cars now feature advanced engine management systems, antilock brake systems, paddle shifters, dataloggers, radios, electric pumps, fans, and lights. All components need to be controlled at the correct moment, and all components require circuit protection to prevent damage or fire.
Traditionally, fuses and relays served all of those purposes, but they have many disadvantages like complicated wiring looms, sensitivity to vibration/temperature, and difficult diagnostics. All of these problems can be solved by using intelligent power management units (PMUs). Our newly developed PMU unit is at the forefront of technology. It provides 16 high current outputs (and use of multiple units if more outputs are required).
One of the main advantages of the PMU is continuous current sensing and self-resetting functionality if current exceeds the defined level. All output state, voltage and current information can be logged and transmitted via CAN bus to dash displays to inform drivers of potential problems. An additional advantage of the PMU system is the ability to define logic for controlling outputs. This is done with data from analogue input channels or CAN bus data, and math operations can be defined for each channel.
The PMU is also equipped with LED indicators to show the status of each output. With use of CAN bus keypads or steering wheel switches, all wiring is vastly simplified and lightened. Two unique features are the inbuilt accelerometer and gyro for logging and “inertia switch” in case of accident.
TECHNOLOGY
The PMU16 is assembled according to 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 and special surface coating ensure reliability even in the harshest environments. Carefully selected components allow for continuous and reliable operation across a very wide temperature range (AECQ-100 GRADE 1 (-40 to 125˚C).

Returns Policy
It is ultimately your responsibility to determine that the parts you order are the correct items for your vehicle model and
year. We will work with you in any reasonable means to ensure the product fits your vehicle build, it would be near
impossible for us to know every vehicle model and if all aftermarket parts will or will not work with them.
Unopened new products may be returned if the following conditions are met. You have made contact with us within 7 days of purchase letting us know you no longer need this time at wardautoracingparts@gmail.com- Please include your order number. You MUST contact us within 7 days of receiving items or a return will not be accepted. All returns are subject to a 10-30% Restocking fee.
We have to email you back agreeing to the return with a RMA Number and return instructions. Once the item is returned to our location we will inspect the item within 3-5 business days. Once we verify the item is still in new condition and able to be resold we will issue the refund minus any fees or shipping at the time of purchase.
Orders that do not meet all criteria may be considered but will receive a restocking fee of 10-30%.
Returns are not permitted for electronic components, Open boxed, damaged or tested parts.
No credit will be given for shipping fees or any form of payment fees. Items must be in brand new condition, in original packaging, containing all original contents, and have not been installed. If items are not new re-saleable condition, we will contact you for further
options. It's up to us to determine if the items Is returnable.
Warranty Policy
We are unable to warranty parts that have not been installed by our shop. If the manufacturer offers a warranty on an item its your responsibility to contact the manufacturer to initiate that warranty claim.
Shipping Claims
Damaged or lost goods are the sole responsibility of the carrier (USPS, UPS, Fedex, ETC.) Title of merchandise passes
from the shipper to the carrier after it leaves our doors, and to the customer delivery. All parts should be thoroughly
inspected upon arrival.
