Global FAQ FOR TUNING

Overview: HOON-Mode is an advanced, switchable feature exclusive to Penta Performance that is programmed directly into your vehicle’s ECU. It allows you to enable or disable performance-related functions on demand while preserving full factory behaviour.

How it works: Your vehicle’s ECU controls many systems, including engine management and Cruise Control. HOON-Mode is an additional logic layer that we program into the ECU and link to the Cruise Control input as a safe activation trigger.

Real-world benefit: This allows features such as crackle behaviour, boost control, and launch functions to remain completely disabled during normal driving, while becoming available only when you choose to enable them.

Cruise Control logic: Cruise Control operates in three distinct stages, which allows HOON-Mode to function without affecting factory operation.

Disabled Stage:
Cruise Control off — HOON-Mode is disabled.

Enabled Stage:
Cruise Control enabled but not actively controlling speed — HOON-Mode is active and performance features are armed.

Engaged Stage:
Cruise Control actively controlling speed — HOON-Mode is disabled.

Why this matters: HOON-Mode never overrides Cruise Control. When Cruise Control is actually in use, HOON-Mode is automatically turned off, ensuring factory behaviour is preserved at all times.

HOON-Mode options:

HOON Boost+
Allows tiered boost levels depending on whether HOON-Mode is enabled or disabled. This gives you a lower-power, conservative mode when off and increased performance when on.

HOON Crackle
Crackle behaviour that is directly linked to HOON-Mode. When HOON-Mode is off, crackle is completely disabled.

HOON Dual Crackle
A multi-stage crackle system controlled via Cruise Control input:
Cruise Control off = Crackle disabled
Cruise Control on = Mild crackle
Cruise Control on + holding “0” = Aggressive crackle

HOON+ Launch
An integrated launch suite including:
• Two-Step Launch Control
• Rolling Launch
• No-Lift Shift

Configuration: All HOON+ Launch parameters are adjustable through the dedicated HOON+ software tab, allowing fine control over behaviour and limits.

Activation requirement: HOON+ Launch relies on a Cruise Control input to arm the system.

Without Cruise Control: Vehicles that do not have Cruise Control cannot currently use HOON+ Launch.

Retrofit option: Many vehicles can be retrofitted with factory Cruise Control hardware and software. Once installed and functioning, HOON-Mode and HOON+ Launch can be enabled.

Factory safeguards: No. HOON-Mode does not interfere with traction control, ABS, stability control, or factory torque monitoring.

Important clarification: HOON-Mode only uses Cruise Control as an activation signal and does not bypass or override core ECU safety logic. All factory protections remain active.

ECU fundamentals: The ECU manages fuel delivery, ignition timing, boost control, and numerous safety strategies.

Factory calibration: OEM software is intentionally conservative to account for varying fuel quality, climate, and emissions requirements.

Flash tuning: Remapping allows us to recalibrate these targets to better suit your vehicle, modifications, and intended use, resulting in improved power delivery, throttle response, and overall drivability.

When it’s required: Tuning is essential when installing upgraded components to ensure the engine operates safely and correctly.

Standard Tune (Flash Tune):
A Standard tune is a vehicle-specific flash tune developed using known ECU definitions and proven data. It provides improved performance and drivability without requiring datalogging or follow-up revisions. This option is ideal for owners who want reliable results with minimal involvement.

Competition Tune (Road-Tuned):
A Competition tune is a fully custom calibration developed through real-world datalogging. This process allows the tune to be refined specifically for your vehicle, modifications, and driving conditions. It is well suited to highly modified vehicles, motorsport use, or customers who want the calibration optimised as far as safely possible.

ECU definition: Every ECU firmware is unique. We begin by reading, backing up, disassembling, and defining the ECU before making any changes.

Map development: Once the ECU is defined, we identify and modify the relevant maps to suit your vehicle and installed hardware.

Road tuning: For Competition tunes, datalogging is used to analyse real-world engine behaviour and apply revisions until the desired result is achieved within safe limits.

Location: We are based in Western Sydney and service vehicles across the Sydney Metro area.

Availability: We are actively expanding our partner network to support customers across Australia and internationally.

No. All tuning is performed through the OBD port. The ECU does not need to be opened or physically modified.

ECU preparation: Each ECU firmware must be disassembled and defined before tuning begins. This ensures accuracy and avoids unsafe assumptions.

Initial turnaround: The first tune typically takes 2–4 business days.

Competition revisions: For road-tuned vehicles, each revision generally takes 1–2 business days, depending on datalog quality, vehicle setup, and required changes.

Depends on the part: Exhaust upgrades can usually be installed prior to tuning.

Important: Certain components, such as turbo wastegate changes, may require tuning before installation. Please contact us to confirm the correct order.

Fuel economy impact: This depends on tune goals and driving style.

Everyday driving: Many customers experience little to no change during normal use.

Performance driving: Aggressive driving and increased load will naturally consume more fuel, which is expected when extracting additional performance.
