Show original supplier description
The K-Tuner KTunerEndR1 is an end-user board tuning system designed for K series engines, enabling users to tune their ECU for enhanced performance. This system includes a circuit board that requires installation into the vehicle's ECU and connects to a laptop via a USB cable for tuning. The KTuner R1 board features 8MB of on-board logging, direct flex fuel support for ethanol content and temperature, four analog inputs for 0-5 volt sensors, and two speed inputs for VR or HALL sensors. It also includes a peripheral port for accessories like Bluetooth modules and LCD displays. This tuning system is compatible with a range of Honda and Acura vehicles, including K-series swapped vehicles, 03-05 Civic Si, 02-04 RSX (with conversion harness), 05-06 RSX Type-S and Base Model, 04-06 TSX, 03-05 Accord (4cyl), 06-07 Accord (DBW), Accord EuroR CL7 and CL9, and 03-06 Element. For K-series swapped vehicles using 02-04 RSX engine harnesses and adapter harnesses, a separate 02-04-to-05-06 ECU adapter harness may be required. **Important Considerations:** This product is sold for competition use only and is not legal for use on public roads or highways. It is intended solely for sanctioned racing events on closed courses. Furthermore, this product is not for sale in the state of California. ECU is not included with the purchase, and installation by anyone other than KTuner or an authorized dealer may void the warranty.
