Can the DCU be used with non-Nitron dampers?

No. The Nitron DCU is designed specifically for use with Nitron elec-TRON coilover kits. It controls Nitron's proprietary proportional solenoid valve and is configured for the specific application location and settings of the R8 platform.

What damping maps are available and how do you switch between them?

The DCU provides access to six pre-installed maps; three passive and three adaptive; via a rotary control switch or visual rotary display. The adaptive maps; Rain, Tour, Sport, and Race; continuously optimize damping in real time within the selected character. The passive maps offer fixed damping behavior for drivers who prefer a static setup. Switching between them is done through the control knob, which can be mounted within reach of the driver.

How fast does the DCU actually process and adjust damping?

The DCU operates at 200Hz, processing data and making damping corrections every five milliseconds. It uses two three-axis accelerometers and a three-axis gyroscope to monitor vehicle attitude, braking, cornering, and acceleration simultaneously. That processing rate means the suspension is reacting to what the car is doing in real time rather than responding after the fact.

Is the DCU weatherproof and durable enough for track use?

Yes. The DCU is fully resin bonded, which protects the internal electronics from moisture, vibration, and the conditions that come with track use. It's supplied with a custom or universal wiring harness and is configured specifically for the application location and settings of the R8.

Description

Nitron elec-TRON DCU for 42 Audi R8

The Nitron DCU is the required control unit for the elec-TRON system on the 42 Audi R8, sold separately from the coilover kits. It transforms the damper setup from a conventional passive system into a precision semi-active platform, with Nitron’s elec-TRON valve making damping adjustments every five milliseconds based on continuous data input from the DCU. Vehicle attitude, braking forces, cornering loads, and acceleration are all assessed in real time to determine the correct valve position and damping level at any given moment. The result is a suspension system that isn’t locked to a fixed damping rate but is constantly working to optimize grip and comfort based on what the car is actually doing. The DCU is fitted with an adjustable control knob giving the driver access to pre-installed damping maps; Rain, Tour, Sport, and Race; each calibrated for a specific driving context. Damping continues to be optimized continuously within whichever map is selected, so the driver determines the overall character and the system handles everything else.

About Nitron Suspension

Nitron Suspension has been at the forefront of precision suspension engineering since 1998, founded by Guy Evans with the goal of building high-performance shocks for enthusiasts and professionals alike. Over 200 dealers now carry Nitron products across Europe, Asia, the US, Australasia, and Africa. In 2008, the company moved into a dedicated facility in the UK’s Motorsport Valley, adding dynamometers, 5-axis CNC machines, and 3D CAD capabilities to support both growing demand and continued product development. A second expansion came in 2023 with a new office in Murrieta, California. The team behind every Nitron product draws from deep backgrounds in machining, materials technology, hydraulics, bike engineering, and F1 racing, with many engineers bringing firsthand experience as competitive drivers and riders. That depth of knowledge across both the technical and competitive sides of motorsport shapes every product Nitron develops.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
