RSX and Swap Platform

KTuner for 05-06 RSX Base and Type-S, 02-04 RSX, EP3, and Swap vehicles.

KTuner is for off-road research and development testing only. Every vehicle should be flashed back to factory before being driven on a public road.

KTuner has a great feature set for the RSX, EP3, and swap platforms.

What are my options?
• KTunerECU End User System – KTunerECU Hardware with software. Datalog and make your own changes – $449

How do I get KTuner?
• Contact a dealer for dealer testing or to order a KTuner kit.

What’s required?
• Your factory 05-06 ECU can be physically modified by a dealer to accept our KTuner development hardware.
• You can also order a prepared 05-06 ECU from any of our dealers.

02-04 RSX, 03-05 EP3, and swap vehicles:
If you’re using an 02-04 engine harness you will need a conversion harness to utilize the 05-06 ECUs our platform is built on.

Will anything change?
• If using an ECU other than factory the immobilizer light on the dashboard will flash. You can disable the immobilizer in the software and unplug the immobilizer unit to prevent flashing on the dashboard or you can have the ECU sync’d to your immobilizer at any Honda/Acura dealer. *If you have already locked your KTuner unit to the ECU unlock it before they sync the immobilizer or tell them not to change the ECU VIN number. If they change the VIN number the KTuner unit will no longer communicate with the ECU if it’s locked to the previous VIN already.*
