Integra DC5 — Stage 2 ECU Tune
- Optimized engine control for K24 swap configuration
- Enhanced air intake flow with Skunk intake system
- Improved exhaust scavenging with custom headers
- Reduced backpressure through 2.5 inch exhaust system
- Precise fuel and ignition mapping for swapped engine platform
This DC5 received the popular K24 swap and landed on a Haltech 1500 standalone for full control. Supporting mods kept it sensible: intake, headers, and a 2.5 inch exhaust to let the bigger motor breathe without overdoing it for daily duties.
The tune focused on drivability and reliability rather than chasing peak numbers. Final result was 118 kW at the wheels with 210 Nm, which suits the chassis well and keeps it tractable around town. The Haltech platform gave us clean fuelling and ignition maps across the range without any of the quirks you sometimes see with adapter harness setups.
Good foundation for a usable street car that still has room to grow if the owner wants to push harder down the track.
Why the K24 over the original K20?
The K24 brings more displacement and torque, which makes for easier street driving and better mid-range pull without needing high-compression or aggressive cams. It's a popular swap for DC5s that stay naturally aspirated.
Is 118 kW low for a K24 with these mods?
Not at all. With basic bolt-ons and no headwork or aggressive tuning, this is a solid naturally aspirated result that prioritises reliability and response over peak power.
Can this tune handle E85 or further mods?
The Haltech 1500 supports flex fuel and has headroom for injectors, cams, or boost if the owner upgrades later. The base map would need adjustment for any fuel or hardware changes.
