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. 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 DC5R Parts provide me with an ECU?

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 to 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.

The modified ECU with a big Hondata sticker on it K-Pro Manager software and USB drivers on a CD Installation instructions 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.
