Overview

The Hondata KPro V4 is a fully programmable ECU solution designed for K-series engines, providing flexible fuel and ignition control, data logging, and advanced features within a modified factory ECU. It connects to a Windows laptop via USB for tuning using KManager software, allowing for edits to fuel/ignition maps, cam angles, and real-time adjustments. This system is essential for K-series engine swaps as it enables immobilizer disabling.
Show original supplier description
The Hondata KPro V4 is a fully programmable ECU solution built for K-series engines, offering advanced fuel and ignition control, data logging, and precise calibration capabilities. This ECU is specifically designed for the 2002–2004 Acura RSX (Base & Type S), 2002–2005 Honda Civic Si, and 2002–2004 Honda CR-V (Manual Transmission), as well as any K Swap utilizing an ECU from those chassis years. It supports features such as expanded ignition and fuel tables up to 11,000 rpm and 60 psi boost, engine protection against lean AFR, overboost, and low oil/fuel pressure, and multi-cam angle tuning for VTEC/VTC. Key features include an 8MB onboard datalogging capacity, live tuning and auto-tune capabilities, and Bluetooth support with the Hondata Mobile app. The KPro V4 also offers adjustable VTEC engagement by load and throttle, rev limiter with fuel cut, and multiple general-purpose outputs for functions like nitrous and boost control. It requires a compatible Honda/Acura ECU core (PRB, PND, PNF, PRA, PRC, PRD, PPA, PPL) and core availability may cause fulfillment delays of 6–8 weeks. Important notes include that this product is for off-road/racing use only and is not legal for use on public roads in the USA. It is not CARB approved. Additionally, all Hondata KPro sales are final once the product is received, and returns are not accepted for used or potentially used units. Confirm compatibility and usage prior to ordering.
