{"product_id":"kpro-v4-engine-management-system","title":"KPro V4 Engine Management System","description":"The Hondata KPro V4 ECU system offers comprehensive tuning capabilities for the 2005-2006 Acura RSX Type-S, addressing the limitations of the factory ECU for performance modifications. This system provides advanced control over crucial engine parameters, including fuel injection, ignition timing, VTEC engagement, cam angles, and boost strategies, making it essential for any RSX owner pursuing significant performance upgrades such as intake, header, exhaust, turbo kits, or engine swaps. The KPro V4 enables users to tune injector size, MAP sensor scaling, and VTEC crossover points, and it also supports immobilizer bypass for engine swaps and includes datalogging features for precise tuning.\n\nThis kit consists of a modified 2002-2004 RSX ECU (PRB, PND, PPA, or PPL) that has undergone internal hardware changes for compatibility with the 05-06 chassis's sensors and outputs. It is supplied with a dedicated adapter harness, eliminating the need for complex rewiring. Key features include USB connectivity for tuning and datalogging via KManager software, onboard 8MB datalogging (10-215 minutes), compatibility with larger injectors and aftermarket MAP sensors, safety strategies for lean conditions, low fuel pressure, and overboost, launch control, anti-lag functions, Bluetooth integration with the Hondata Mobile App, flex fuel capability, and expanded mapping for up to 60 PSI boost and 11,000 RPM.\n\nBuyers have several core options: sending in their own compatible ECU for modification, or purchasing a pre-modified unit supplied by Hybrid Racing, either a PND base model ECU or a PRB Type-S ECU. The PRB option is more expensive but retains full feature access, including reverse lockout functionality, making it the preferred choice for many RSX Type-S customers seeking the fewest compromises.\n\nImportant considerations for installation and use include:\n\n*   **Chassis Certification:** The 05-06 KPro is certified exclusively for use in the 2005–2006 RSX chassis.\n*   **Sensor Compatibility:** Some sensors may need to be disabled to prevent ECU errors. The 05-06 O2 sensor is incompatible; an O2 sensor from an 02–04 RSX or 02–05 Civic Si must be used.\n*   **Cruise Control:** Cruise control performance may be affected at higher speeds due to differences in speed sensor signals.\n*   **Usage Restriction:** This product is intended for off-road or racing use only and is not legal for highway use in the United States.","brand":"Hondata","offers":[{"title":"Default Title","offer_id":52688729014584,"sku":"HON-KPRO0506","price":1070.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664206724.webp?v=1784893870","url":"https:\/\/store.motormia.co\/products\/kpro-v4-engine-management-system","provider":"MOTORMIA","version":"1.0","type":"link"}
