KManager is Windows software which allows re-programming and datalogging
from the K-Series Programmable ECU
latest KManager software
latest beta version (if any) is available from the Hondata
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
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.
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 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
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.
For advanced high boost use, individual cylinder fuel trim gives extra fuel
to any hot running cylinders for increased reliability.
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
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
Several of the major sensors can be displayed in large, easily identified
numbers. Great for road or dyno use.
- 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
- 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.
