The K-Series Programmable ECU (K-Pro) consists of a hardware modification to any K-Series ECU, plus Windows software which allows you to re-program the ECU and datalog sensors.

On-board datalogging is standard on all K-Pros from serial number 4111 (version 2)and above.  For more information go here. Additional analog inputs and double the datalogging memory now available with the K-Pro V3. K-ProV3  supersedes all previous versions.

 
Counterfeit and on-line auction site warning
It has come to our attention that counterfeit KPros  - green circuit board Versions 1 and 2 are being sold as new and used. Protect yourself from purchasing a counterfeit K-Pro.

Features

Main features:

  • Fits inside the ECU
  • Designed and assembled in USA
  • USB connection for speed and compatibility
  • KManager Windows based software for parameter & table editing, calibration uploading and datalogging.
  • Many built in calibrations for common engine combinations
  • Built in datalogging to a laptop
  • On board datalogging memory (2 MB memory, 10-110 minutes datalogging)
  • Adjustment for different sized injectors, with overall fuel trim.
  • Configurable for any MAP sensor (to 5 Bar and above)
  • TPS based table lookup for ITBs
  • Engine protection from over boost and lean protection.
  • Expanded fuel and ignition tables, both in rpm and load, to 60 lbs boost and 11,000 rpm (these are not the upper limits)
  • Launch control with anti-lag
  • Three multi purpose outputs for nitrous control or similar
  • Supports lambda tracing from the stock wideband o2
  • PWM output for boost control

KManager editing software features:

  • High and low speed 16 x 20 ignition and fuel tables for correct VTEC tuning
  • Injector size fuel trim
  • Fuel trim for starting, throttle tip in and individual cylinder trim
  • Rev limiter with fuel cut
  • Launch control with anti-lag
  • Adjustable VTEC window with load and throttle control
  • Adjustable idle speed
  • MAP sensor type and calibration
  • Adjustable boost cut with hot and cold settings
  • Closed loop control
  • Air temperature compensation
  • Fuel and ignition correction based on gear
  • Closed loop
  • Three general purpose outputs for nitrous control, quad boost control or similar
  • On board datalogging trigger conditions

Application Notes

  • Base maps are included only for K20A2, K20A3 (RSX Base), K20A3 (Civic SI) and K20A engines.
  • The 2002- CRV ECU (5 speed) (PPA -A0# ECU) can be used.
  • Support for the manual K20A3 engine and the secondary intake runner as used in the base model RSX and CRV. 
  • The Japanese PRD and PRC ECU do not support a fuel tank pressure sensor required for some US emissions tests, but will likely pass a tailpipe sniffer test if the catalytic converter is in place.
  • PNF, PPA and PND ECUs for 5 speed transmissions will not operate the reverse lock solenoid on 6 speed transmissions.
  • The K-Pro ECU will not work on Automatic vehicles.  Automatic ECUs cannot be converted to manual.
  • To use the K-Pro on a 2005-2006 RSX, an adapter harness is required, an 02-04 specially modified ECU must be modified for used and the primary oxygen sensor from an 03-04 must be used.
  • Turn around time is usually 2 days from the time it is received.

General Notes

  • From previous ECU's Honda has changed from 2 dimensional tables (engine speed and engine load) to 3 dimensional tables (engine speed, engine load and cam angle). The K-Pro ECU retains these 3 dimensional tables to ensure the engine is running at optimum efficiency and power for every cam angle.
  • The stock JDM and US O2 sensor is wide band and can read from 11.5:1 to 30:1 A/F ratios.
  • Most OBDII features may be disabled for race vehicles.
  • Error codes and the OBDII readiness status may be datalogged.
  • Base tables are supplied for the RSX Type S, RSX Base, Civic SI and Integra Type R engines. These tables have been dyno tuned.
  • No external programmer or other equipment is necessary. Just plug the ECU into a laptop via a USB cable.
  • Tables may be map-traced in real time.
  • The K-Pro ECU is not real-time updateable, however most changes to tables and settings can be uploaded in 1-2 seconds. 
  • The K-Pro ECU is a separate product from the s100/s200 line, and will not share the same options (e.g. 3 step) nor software (HondaLogger, RomEditor). All systems are fully programmable by the user. All K-Pro ECU systems include all features (e.g. boost, datalogging).

Feedback

THE VERDICT: Hondata K-pro is the sh_t!! Ever since I got my RSX, I never seemed to bond with the car like I did with my Old civic Si... I tried putting bolt ons, making it look pretty, a turbo kit and nothing seemed to helped it.... but the I added K-Pro.. and its a different story. The car feels and pulls sooooo strong its unbelievable. I raced my friend with a turbo prelude, port and polish, higher boost etc, and i can literally say that I left him like he was standing still! Before Hondata we were pretty much dead even all the way to 100. Yesterday, I gave him a 2 second lead and I railed him in soooo fast that I thought that he had either let off or slightly tapped the brake... needless to say, it made me fall in love with my car again!!
