Description

The Hondata KPro4 is a powerful programmable ECU built for K Series engines, offering extensive control over engine parameters. It boasts adjustable VTEC engagement and on-board VTEC solenoid control, along with adjustable launch control and anti-lag features for performance driving. For boosted applications, it provides PWM boost control with integrated boost cut, overboost protection, and AF lean protection. The KPro4 also includes safety features like low oil pressure and low fuel pressure protection. It offers 8MB of onboard datalogging memory, capable of recording up to 215 minutes of data, and supports Bluetooth connectivity for wireless data transfer and monitoring via the Hondata Mobile app. This ECU is compatible with K Series engine swaps using ECUs from 2002-2004 Acura RSX, 2002-2005 Honda Civic Si, or 2002-2004 Honda CR-V models. It is important to note that for 2005-2006 RSX models, an adapter harness and a specially modified 02-04 ECU are required, and automatic RSX transmissions are not supported. Lead times for conversions can be 6-8 weeks, and all sales are final.
