NO ECU IS INCLUDED WITH THIS PURCHASE. YOU ARE RESPONSIBLE FOR SENDING IN AN ECU CORE.
PLEASE NOTE: IF YOU HAVE THE 2005-2006 RSX AND WISH TO USE THE KPRO YOU MUST SEND IN A 2002-2004 RSX TYPE S ECU. NO OTHER ECU IS COMPATIBLE WITH THE THE 2005-2006 RSX KPRO.
What is the K-Pro ECU?
The K-Pro ECU is a specially modified 2002 to 2004 Honda ECU with a USB interface to a notebook PC running Windows XP. It is currently available for the standard shift Acura RSX base model and Type-S, the US Civic Si and the Euro Civic Type R. K-Pro ECU Manager software allows the setting of cam angle, ignition advance, fuel, and a variety of other aspects. The purpose of the K-Pro ECU is to fine-tune the Honda ECU for best possible engine performance under various operating conditions and with various engine configurations. It also allows you to disable the immobilizer which is particularly important to those people performing engine swaps.
What ECU do I need to send in? Can Hybrid Racing provide me with an ECU?
Hybrid Racing does NOT provide you with a compatible ECU. You must mail your ECU to Hybrid Racing as long as it is on the list below:
Who should use it?
Anyone who wants to a) take full advantage of modifications, from simple bolt-ons to extensive engine work, by tuning the engine specifically for those modifications, b) monitor the engine via data logging, and c) learn how numerous variables inside the engine relate to one another and how they are influenced by making changes to fuel delivery, ignition timing, cam angle settings, and other variables.
The K-Pro is far more than just another performance modification. It is a tool to monitor and change the operation of the ECU which, in turn, monitors and orchestrates the operation of standard “conventional” modifications such as less restrictive air intakes, headers, intake manifolds, cams, exhaust systems, and even super and turbochargers.
Unlike those “passive” modifications, the K-Pro is an “active” modification. Its operation must be learned and understood. If used properly, the K-Pro is key to unlocking the true potential of a Honda engine. If not, it may become an incomprehensible source of frustration. It may even harm the engine if inappropriate changes are made and uploaded into the ECU. A prospective K-Pro user should, therefore, expect a learning curve. Those unfamiliar or unwilling to learn K-Pro operation and the principles behind it can still use the K-Pro to good advantage, but they should expect to pay a tuner to tune the car properly. Tuning may be necessary not only to get the best possible performance but also because the base K-Pro calibration may cause the engine to knock. That’s because unlike the Hondata reflashes which are safe one-size-fits-all maps, the K-Pro calibrations are much more aggressive because, after all, K-Pro users can always modify the calibrations to make them fit their engines.
Those willing to spend the time learning the K-Pro will find it an incredibly powerful tool for unlocking the true potential of their engines. Those do not feel up to it and do not want to foot the expense of having a professional tune their K-Pro can always resort to Hondata’s static ECU reflashes.
What you receive
The modified ECU with a big Hondata sticker on it
K-Pro Manager software and USB drivers on a CD
A six-foot USB cable
2 silver Hondata stickers
The modifications included installation of a 1.75 x 4.5-inch Hondata-branded daughterboard. This required soldering a couple of connectors onto the motherboard. I analyzed the daughterboard because I was curious as to what it does. The two main chips on it are:
In addition, Hondata made a small cutout in the rear wall of the ECU housing to accommodate a standard USB connector. As is usually the case with USB peripherals, the USB driver must be installed before the ECU is plugged in for the first time. After that, the ECU can be connected to the computer even if it is not in the car. The PC will then recognize it and install the proper driver. When it first came back, I simply connected the K-Pro ECU to my notebook and installed the USB driver. Then I put it back into its mounting bracket in the passenger footwell of the car and reconnected the various cables.

Kpro Version 4 Updates
The KPro4 uses a faster processor with more capability than the KPro-III. This allows the KPro4 to perform more tasks without slowing down the ECU, like live tuning, output to a dash, flex fuel and advanced protection. Calibration uploads and data logging from a laptop are also faster.
Enhanced onboard data logging
The KPro4 has double the data logging memory (64 MBit) of the KPro-III and can datalog at double the rate (100 Hz), giving an onboard recording time of 10 - 220 minutes.
Faster upload & data logging
The upload time is 30% faster than the KPro-III, with a typical initial upload time of 7 seconds. Subsequent uploads are also faster, and live tuning can be used for instantaneous updates.
Laptop data logging is also 30% faster than the KPro-III.
Live tuning & autotune
Main tables can be updated in real time, without affecting the operation of the engine. This allows dyno tuning without pausing to upload.
Autotune uses live tuning and a laptop to tune fuel tables as you drive.
The KPro4 includes Bluetooth for data logging and tuning wirelessly with a laptop without a USB cable, and mobile data logging on an Android or IOS device.
Ethanol sensor input
An ethanol sensor can be directly connected to the KPro4, allowing flex fuel operation, with adjustments to fuel & ignition tables, performed automatically based on fuel ethanol content.
Speed sensor input
A speed sensor input can be directly connected to the KPro4 and sent to the ECU. This is configurable to any pulse based sensor and eliminates the need for a stock speed sensor.
Dash & data logging outputs
The KPro4 has a serial output (both TTL & RS232) and CAN output so that a dash can be driven from the KPro. The AiM MXL, Racepak & generic CAN outputs are supported.
Advanced protection options use the KPro4 analog inputs and engine information to intelligently shut down the engine when the conditions might be dangerous to the engine.
Better wideband support
The KPro4 can process a wideband lambda input (either analog or digital) and allow the ECU to run in a closed loop from an aftermarket wideband without requiring the stock o2 sensor.
