Product Details
| Part Number: | HON-KPRO-WITHECUC |
| Brand: | Hondata |
| CARB Approved: | No |
The Hondata KPro V4 represents a fully programmable ECU solution designed for 2002–2004 Acura RSX (Base & Type S), 2002–2005 Honda Civic Si, and 2002–2004 Honda CR-V (Manual) factory ECUs. It serves as the tuning platform for K-series engines, delivering flexible fuel and ignition control, data logging, and advanced control features within a modified factory ECU. For your installs that involve turbocharged K-series builds or high-compression all-motor setups, KPro V4 provides the tools to execute precise calibrations.
The KPro V4 mounts inside the stock K-Series ECU and connects to a Windows laptop via USB. Using KManager software, your installer can edit fuel and ignition maps, adjust cam angles, enable launch control, and perform real-time tuning. It is one of the few systems that enables immobilizer disabling, making it essential for K-Series engine swaps.
PRB ECU cores are available. A PRB core enables nitrous and boost control within Hondata. Core availability is limited to stock on hand; if a configuration shows as unavailable, please contact us to arrange purchasing.
