Haltech Nexus R5 VCU (universal)
80% of the products in our store are in internal or external stock and we can often process your order quickly (varying from a few hours to a number of business days).
Naturally it is possible that a product has an (unexpected) longer delivery time.
Upon receipt of your order, we will always inform you about this and offer any available alternatives.
We deliberately provide stock information about our products afterwards, because many suppliers do not offer a ''stock link system'' and we do not want to show '' estimates '' in advance, like many other webshops do (which are often incorrect and give you wrong information in advance).
We only want to give our customers actual information on the moment of processing the order so we don't mislead our customers.
If you need a product VERY quickly and you need to be sure that we have it in stock, please e-mail or call us or send a message via ''ask a question about this product''.
Haltech Nexus R5 VCU.
The Haltech Nexus R5 VCU (Vehicle Control Unit) is the standalone flagship control system in the Haltech lineup, designed for elite racing applications and custom wiring projects. This ultra-powerful device seamlessly integrates a state-of-the-art engine management system, a power distribution module (PDM), a dual-channel wideband controller, and a high-capacity data logger into a single unit. By combining these advanced systems, the Nexus R5 simplifies your vehicle's entire electrical architecture, reducing weight and eliminating the need for external modules. It is suitable for complex engine configurations up to 18 cylinders or multi-rotor setups, offering unmatched power management and advanced tuning features.
