Holden ZB Commodore Dyno Tune | AFM Delete, Power & Torque Gains

If you think a high-mileage car can’t perform like new, think again. This Holden ZB Commodore dyno tune proves that with the right upgrades and ECU calibration, even a daily driver with over 315,000km can feel completely revitalized.

In this blog, we’ll walk through a recent dyno tuning session for a Holden ZB Commodore (over 315,000km) where we removed AFM, optimized fueling and spark tables, and unlocked the transmission for serious gains in both power and drivability.

The Problem with AFM on Holden Commodores

Active Fuel Management was designed to improve fuel efficiency, but in reality, it often causes issues like rough running, loss of torque, and long-term engine wear. Many Holden tuning specialists recommend AFM removal as one of the first steps to improving both performance and engine longevity.

Dyno Tune Process: What We Did

For this ZB Commodore, here’s what our team carried out:

• AFM Delete – to prevent premature wear and improve consistency.

• Fuel & Spark Optimization – recalibrated fueling and spark tables for better throttle response.

• Torque Enhancement – dialed in low-to-mid range torque for stronger pull in daily driving.

• Transmission Calibration – unlocked and tuned via bench tuning for smoother, more responsive shifts.

Dyno Results: Before vs After

📊 Here’s what the numbers looked like on the dyno:

• Before: 408.4 Nm / 187.8 kW

• After: 440.8 Nm / 211.8 kW

That’s a solid jump in both torque and power, with noticeable improvements throughout the entire rev range.

Benefits Beyond the Dyno

Apart from the performance gains, this Holden Commodore is now set up for:

• Better fuel economy thanks to refined fueling.

• Longer engine life by eliminating AFM-related stress.

• Improved drivability with smoother gear changes and stronger acceleration.

Even with over 315,000km, this ZB Commodore now feels fresh, responsive, and ready for many more kilometers on the road.
