Which retard function is programmed in increments from 0 to 15 degrees in 0.5-degree steps?

Which retard function is programmed in increments from 0 to 15 degrees in 0.5-degree steps?

• A. Tuning software
• B. Launch retard
• C. Step retard
• D. Individual cylinder timing

Answer: (B)

The concept being tested is a function that retards ignition timing specifically during the launch phase with fine-grained control. Launch retard is designed to back off spark timing as the car starts moving, helping prevent wheel spin and control torque. The description matches this function because it’s adjustable in small increments—from 0 up to a maximum, typically around 15 degrees, in steps as small as 0.5 degrees, giving precise traction tuning for the launch. This makes it the best fit for a feature meant to manage launch dynamics with high precision. Other options describe different timing controls—step retard would retard timing in stages but not necessarily tied to launch, individual cylinder timing targets each cylinder separately, and tuning software is the general platform rather than a specific launch-focused function.
