Tuning the Honda K20 (DC5) – High Revving VTEC on Hondata

The Honda DC5 Integra Type R is an icon for a reason – lightweight, sharp handling, and powered by the legendary K20 engine. Known for its screaming VTEC powerband and razor-sharp throttle response, the DC5 is a perfect candidate for a precise ECU calibration.

The Setup

This particular DC5 came to Motorworx running a well-maintained K20A with supporting intake and exhaust upgrades, ready to be dialled in on Hondata. The owner’s goal was to maximise usable mid-range torque while retaining the high-revving excitement the K20 is famous for.

On the Dyno

Once strapped to the rollers, the Hondata system (mated to the factory Honda ECU) allowed us to fine-tune fuelling, ignition, and VTEC engagement. The results were impressive – crisp throttle response, stronger pull from the mid-range, and a seamless transition into VTEC that keeps the engine charging hard all the way to the redline.

The Result

With its new calibration, the DC5 feels sharper than ever. The Hondata tune not only unleashes extra power but also refines drivability, making this high-revving K-series even more rewarding both on the road and track.

At FC Tuning, we bring out the best in every setup – from turbocharged builds to naturally aspirated screamers like this fast road DC5 K20.
