Why Choose the AccuSpark Performance Curve?

Many original Beetle distributor curves were designed during the 1970s emissions era, prioritising fuel economy and emissions compliance rather than engine performance.

The AccuSpark performance curve has been developed with modern enthusiasts in mind.

Compared with the standard factory curve, the AccuSpark curve provides:

Stronger mid-range advance
Ignition timing increases earlier through the rev range, improving combustion efficiency where road engines spend most of their time.

Sharper throttle response
The engine responds more quickly to throttle input, making the car feel livelier and more engaging to drive.

Improved drivability
Acceleration feels smoother and more progressive without the flat mid-range often associated with factory emissions-era distributors.

Better suited to modern fuels and upgrades
The curve works particularly well with common enthusiast modifications such as performance carburettors, improved exhaust systems, and modern unleaded fuel.

The Result

Compared with a typical factory distributor curve, the AccuSpark curve helps the engine feel:

quicker, more responsive, and less flat through the mid-range.
