Upgrades

KPro upgrades should use this form

2001-2005 D17 Civic DX, LX, HX & EX Manual transmission only (US vehicles only)

The K-Pro for the D17 consists of a hardware modification to a donor K-Series ECU, a specially modified cam timing wheel, plus Windows software which allows you to re-program the ECU and datalog sensors.

To order, fill out this form and contact a Hondata dealer. Turn around time is usually 2 days from the time the ECU is received by Hondata.

Warning

Within the USA this product is legal only for racing vehicles which may never be used upon a public highway.

Application Notes

• The stock D17 ECU cannot be converted to a programmable ECU. A new RSX-S ECU or donor ECU must be used.
• The Hondata adjustable cam pulley has specially modified timing teeth. The stock timing wheel will not work.
• The Civic HX and all 2004-2005 Civics use a wideband 02 sensor compatible with the K-Pro.
• Base maps are included for a stock D17 non VTEC Civic and a D17 non VTEC turbo.
• The K-Pro ECU will not work on automatic D17 Civics.
• Any K-Pro used on a 2002-2004 RSX-S will work provided the Hondata cam gear is used.

Donor ECUs

ECUs for the D17 may be sourced from the following vehicles

• 2002-2004 RSX Base 5 speed (PND -A0 ECU)
• 2002-2004 RSX Type S 6 speed  (PRB-A0 - ECU)
• 2002-2004 CRV 5 speed (PPA-A0 ECU)
• 2002-2005 Japanese DC5 Integra Type R (PRC ECU)
• 2003-2005 Japanese Civic Type R (PRD ECU)
• 2002-2005 Civic Si (PNF ECU)

General Notes

• All 2004-2005 Civics and the 2001-2003 Civic HX use a compatible wideband 02 sensor. Two wires need to be moved for rear O2 operation.
• The 2001-2003 Civic DX, LX & EX Civics use a narrowband 02 sensor. Two wires need to be moved for closed loop operation.
• If you plan a K engine swap, install the appropriate engine harness and switch on VTC in the KManager software.
• 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 via USB.
• Most OBDII features may be disabled for race vehicles.
• The D17 knock sensor is incompatible with the K-Pro and must be disabled in the KManager software.
• Error codes and the OBDII readiness status may be datalogged.
• The K-Pro ECU can be matched to the Civic immobilizer system. See here for details.
• For training materials see here.

Installation

• The adjustable cam pulley is shaped differently than stock. You will need to remove the power steering pump and alternator and loosen the engine mount.
• Removing the stock ECU is fairly involved. There are three choices for the K-Pro installation:

1. The K-Pro can be installed in the location of the stock ECU.
2. The K-Pro circuitry can be installed into the Civic's stock ECU case. You will need to cut a USB hole.
3. The K-Pro ECU can be installed in the glove compartment. You may need to cut the rear plastic.

2004-2005 DX/LX/EX & 2001-2005 HX installation

For the Civics that use a wideband sensor you need to move two wires to activate the rear O2 sensor. If you have OBD 2 disabled and do not need to use the secondary O2 then it is not necessary to move the wires.

2001-2003 DX/LX/EX installation

These Civics have a narrowband O2 sensor. The donor US ECUs (see above) are designed to run by default with a wideband front O2 sensor. So we use a European PRA calibration, which is designed to run with a front and rear narrowband O2 sensor, feed the voltage from the Civic's front O2 sensor into the K-Pro's rear O2 sensor input, and alter the K-Manager software to run closed loop from the secondary O2 input. In this situation OBD II must be disabled.
