Commodore VE — Stage 3 ECU Tune
- 17% power increase
- 11% torque increase
- Improved fuel efficiency
- Enhanced engine responsiveness
- Optimized air intake flow
This VE Commodore moved past bolt-ons with a 233/238 VCM camshaft, CNC ported heads, and a MAFless over-the-radiator intake. The factory ECU was retained, and the file was built to suit the new airflow and valve events without speed density.
The workshop supplied dyno results showing 286 kW and 458 Nm at the wheels, up from 244 kW and 415 Nm in factory trim. That's 42 kW gained, which sits right where you'd expect for this combination on 98 RON.
Calibration centered on ignition timing, fuel delivery, and cam phaser control to match the new valve profile and unrestricted induction path. The car pulls cleanly through the mid-range where the ported heads and cam do their work.
Can the factory ECU handle a cam and head package like this?
Yes. The factory ECU has the authority to retune fuel, timing, and cam phasing for a moderate naturally aspirated build. A MAFless tune removes the airflow meter as a constraint.
What power gain should I expect from a similar L98 build?
This one gained 42 kW at the wheels with a 233/238 cam, ported heads, and intake on 98 RON. Results will vary with compression, head work quality, and how well the intake flows.
Is this suitable for daily street use?
The cam spec is moderate enough for street manners, though idle quality and low-rpm drivability will be compromised compared to stock. It's a usable weekend car if expectations are set correctly.
