Are you looking to take your Honda or Acura’s engine performance to the next level? The Hondata S300 Obd2 system is a powerful and versatile engine management solution designed to work seamlessly with factory OBD1 Honda engine computers. This upgrade allows you to precisely tune your vehicle for a wide range of modifications, from simple bolt-on enhancements to high-performance racing applications. Whether you’re aiming for improved street performance or building an all-out race machine, the Hondata S300 offers the control and features you need to maximize your engine’s capabilities.
The Hondata S300 is installed into a customer-provided Engine Control Unit (ECU), ensuring a tailored upgrade for your specific vehicle. To ensure a smooth installation process, your ECU should be in good working condition. If you have an automatic ECU that is compatible, it can be converted to manual specification at no extra charge. Even if your ECU has been previously socketed or chipped, installation is still possible, provided the prior modifications were performed correctly.
Getting started with the Hondata S300 is straightforward. Simply select the “S300 Unit + Installation Into Customer’s ECU” package, and add any optional upgrades such as new capacitors, a PWM boost control package, or a custom basemap to suit your modifications. After placing your order, you will receive an email containing an invoice and detailed instructions for mailing in your ECU for the upgrade. The typical turnaround time for the installation is just 2-4 business days, with an additional 2-3 business days for return shipping, minimizing downtime for your vehicle.
