* 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 wideband 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).
2005-2006 RSX owners are at a slight disadvantage when looking to add a Hondata K-Pro programmable unit to their vehicle. The 2005-2006 RSX Type-S model ECU has been documented to use a different processor and countershaft speed sensor that spins 100 times faster than the older 2002-2004 ECU. The variations between the older model ECU and newer Type-S requires the '05-06 RSX owners to either purchase one of the few compatible ECU's listed above in our parts section or purchase a new unit outright from Hondata which we did for an additional $600 (not including the K-Pro).
Compatible ECU: (PRB) 2002-2004 U.S. RSX Type-S ECU, 2002-2004 (PRC) Integra DC5 Type R JDM ECU, 2003-2004 (PRD) Civic Type R JDM

Drop any aftermarket camshaft into your import ride without proper engine management tuning and it's a sure bet that horsepower gains will be minimal at best. Programmable ECU hardware such as the K-Pro has the unique distinction of re-programming the factory ECU and datalog sensors to provide the maximum horsepower potential, whether your drive a high-horsepower N/A vehicle or a turbocharged monster. With a simple plug-in of the jumper harness adapters and the newly modified ECU in place, the laptop was fired up and programmed within an amazingly short time period. The vehicle quickly responded to the newly adjusted maps as a pickup of 22 hp at 2300rpm. The most obvious gains over our previous dyno run were graphed at 5000rpm to 7200rpm where a significant increase of 17hp and 18 lb-ft of torque in the midrange was obtained as the increase continued until our newly revised redline of 8600rpm. In order to optimize the horsepower and torque on the newly programmed K20 powerplant, we used the K-Pro to lower the VTEC crossover point from its factory 5800rpm to a lower 4800rpm. In lowering the low cam to high cam transition, the powerband was not only smoothed out, but also served to benefit the engine in the midrange.
