{"product_id":"k-pro-v4-ecu","title":"K-Pro V4 ECU","description":"The Hondata K-Pro V4 is a fully programmable engine control unit engineered to provide complete tuning control for the 2005-2006 Acura RSX Type-S. It grants users full command over critical engine parameters including fuel delivery, ignition timing, VTEC engagement, cam phasing, and boost control strategies. This system is essential for those moving beyond basic bolt-on modifications and seeking to calibrate their engine for optimal performance, whether for naturally aspirated setups, turbochargers, or larger K24 swaps.\n\nThis K-Pro V4 package involves a modified 2002-2004 RSX ECU (specifically PRB, PND, PPA, or PPL variants) that has undergone internal hardware modifications to ensure compatibility with the 2005-2006 RSX sensors and outputs. It is supplied with a dedicated adapter harness, eliminating the need for complex wiring or repinning, making for a plug-and-play installation. The system connects via USB to a laptop running KManager software, enabling real-time tuning, comprehensive datalogging, and live parameter adjustments. Advanced features include onboard 8MB datalogging, support for larger injectors and aftermarket MAP sensors, safety strategies for lean conditions and overboost, launch control, anti-lag functions, Bluetooth integration with the Hondata Mobile App, flex fuel capability, and expanded mapping ranges up to 60 PSI boost and 11,000 RPM.\n\nUsers have multiple options for acquiring the K-Pro V4. One option is to send in their own compatible ECU for modification. Alternatively, Hybrid Racing offers to supply a tested and verified used OEM PND base model ECU or a PRB Type-S ECU. The PND ECU option is typically less expensive but does not retain reverse lockout functionality. The PRB Type-S ECU option is more costly but preserves all original features, including reverse lockout, making it the preferred choice for many Type-S owners seeking a less compromised setup.\n\nImportant compatibility notes and limitations apply. The 05-06 KPro is certified exclusively for use in the 2005-2006 RSX chassis. Certain sensors may require disabling to avoid ECU error codes. The 2005-2006 O2 sensor is incompatible; an O2 sensor from an 02-04 RSX or 02-05 Civic Si must be used instead. Cruise control performance may be affected at higher speeds due to differences in speed sensor signals. This product is intended for off-road or racing use only and is not street legal in the United States.","brand":"Hondata","offers":[{"title":"Default Title","offer_id":52688722788664,"sku":"HON-KPRO0506-PND","price":1070.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662668611.webp?v=1784893806","url":"https:\/\/store.motormia.co\/products\/k-pro-v4-ecu","provider":"MOTORMIA","version":"1.0","type":"link"}
