KManager is Windows software which allows re-programming and datalogging from the K-Series Programmable ECU.

Download the latest KManager software here. The latest beta version (if any) is available from the Hondata forum.

System requirements

Windows XP / Windows Vista / Windows 7 / Windows 8, 256 Mb RAM, integrated USB and with internet access.

Note: The software will run on Windows XP, Vista, 7 & 8 32bit and 64bit.

Built in Calibrations

Over thirty different calibrations ship for four different ECU types ship with the K-Pro. Included is a calibration similar to the Hondata # 4 reflash and the K20A (ITR reflash). Each calibration here has taken about 8 hours of dyno tuning. More boost and more RPM will require bigger injectors. All tuning done with stock or RC injectors.  It is still recommended to tune your car on the dyno as the specifications for the cars tuned in the calibrations will not exactly match your car.

Boost

Boost is mapped to 11 psi (0.8 bar) using the stock map sensor and 28 psi with replacement MAP sensors. No additional hardware other than larger injectors is required or recommended to use the boost maps in a K series engine.

Nitrous

The K-Pro ECU upgrade is nitrous aware. Arm the nitrous and have the nitrous relay operated on one of several outputs. The K-Pro ECU on switching the nitrous relay will simultaneously retard the ignition and add fuel. A dry kit and bigger injectors are highly recommended although this will drive a wet kit by switching both fuel and nitrous relays simultaneously. This operates in conjunction with any form of NA or forced induction tuning.  The nitrous feature will not work on the PRA, PRC or PRD ECU's.

VTEC

VTEC can now be switched on base on RPM and air pressure. This means you can have VTEC at a low RPM for supercharging and big cams and at a higher RPM for part throttle.

Closed Loop

The US and Japanese K series engines use a wideband front oxygen sensor capable of maintaining a steady accurate air/fuel ratio even under wide open throttle. This causes problems in boosted cars where it is possible to achieve significant boost levels at partial throttle while the ECU is trimming fuel to 14.7. This lean condition is not good for the engine and causes hesitation. This problem is not often seen on the dyno where runs are done at full throttle. This problem is most commonly seen rolling onto the throttle from a cruise.

Hondata can now switch your ECU to open loop based on boost pressure which will make your boosted engine run safer and smoother.

Parameters

For advanced high boost use, individual cylinder fuel trim gives extra fuel to any hot running cylinders for increased reliability.

ECU options

For race car use, the immobilizer, OBDII and all associated sensors can be switched off and removed, simplifying your wiring. The multiplexer (amongst other things) transmits information to the gauge cluster - for example water temperature.

Datalogging

Datalogging is done via the USB cable to a laptop. Systems with a serial number of 4111 or greater, sold after 8/3/07, have an on-board datalogging capability. More information about on board datalogging for the KPro.

Datalogging graphs can display up to 4 charts of 4 sensors each in any combination.

Display

Several of the major sensors can be displayed in large, easily identified numbers. Great for road or dyno use.

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 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.
