What is ECU Tuning?

ECU tuning is the process of enhancing your vehicle’s performance by adjusting the engine management software. Whether you’re looking to gain more horsepower, torque, fuel efficiency, or a better driving experience, performance tuning offers tailored solutions for your goals.

At BitPerformance, we make the process easy — with our fully equipped mobile workshop, we come to your home or workplace.

ECU tuning isn’t just for sports cars. Everyday vehicles like cars, vans, and commercial fleets can benefit too.

Why Consider ECU Tuning?

🔧 Increased Power & Acceleration
Unlock hidden potential by optimizing boost pressure, fuel delivery, and torque — for sharper throttle response and quicker performance.

⛽ Improved Fuel Efficiency
A well-tuned engine can burn fuel more efficiently, reducing consumption under normal driving conditions.

🚗 Better Driveability
Enjoy smoother power delivery, responsive handling, and a more refined driving experience.

🎯 Tailored to Your Needs
Whether you want economy, power, or a balanced setup — we adjust the map to match your driving style.

ECU Remapping by BitPerformance

We specialize in custom ECU remapping, the most advanced method of tuning modern engines. This involves reprogramming your vehicle’s ECU to safely adjust parameters like:

Fuel injection

Ignition timing

Turbo boost

Torque limits

Throttle response

Included in Our Tuning Services:

✔ Stage 1 & Stage 2 ECU Remapping
✔ Safe and tested engine optimization
✔ Mobile service across Dublin & surrounding areas
✔ Diagnostics and post-remap verification

What Is a DPF Clean?

A DPF (Diesel Particulate Filter) clean involves restoring the filter’s ability to trap harmful soot and particulate matter from the exhaust gases in diesel vehicles.
Over time, these particles build up and restrict exhaust flow, causing poor performance, high fuel consumption, and even limp mode.

🔎 DPF Health Check & Cleaning Process

At BitPerformance, we always begin with proper diagnostics:

1. Diagnose – We identify whether the issue is truly with the DPF or caused by an underlying fault (e.g. sensor, EGR, turbo leak, etc.).

2. 2-Stage Chemical Cleaning – If required, we perform a full DPF clean using pressure-based, on-car chemical methods.

3. Post-clean Testing – We confirm pressure levels and soot readings to ensure the system is back to normal.

> ⚠ Note: In many cases, a clean is not necessary. We regularly find that a blocked DPF is a symptom, not the actual problem.

Common root causes include:

Faulty temperature/boost sensors

Glow plugs or fuel vaporizer failure

EGR valve or EGR cooler faults

Turbo leaks or cracked manifolds

Intake/intercooler leaks

Stuck thermostat preventing regeneration

✅ Why Choose a Professional DPF Clean?

✔ Restored Fuel Efficiency
Unclogging the DPF improves engine breathing, leading to better fuel economy.

✔ Reduced Emissions
A clean filter significantly reduces harmful soot emissions, keeping your vehicle compliant.

✔ Extended Filter Life
Prevent excessive ash buildup and avoid the high cost of replacement.

✔ Improved Engine Performance
Reduce turbo lag, restore lost power, and eliminate limp mode issues.

✔ Lower Maintenance Costs
Professional DPF cleaning is far cheaper than replacing the filter — and safer than a risky forced regen.

✔ Increased Engine Longevity
A clean exhaust system means a healthier engine over time.

> 🚫 We do not perform unnecessary forced regenerations. Instead, we fix the real cause so regeneration happens naturally and safely.

What Is Engine Carbon Clean?

Engine Carbon Clean is a hydrogen-powered treatment designed to safely remove carbon deposits from inside your engine — without chemicals, without dismantling, and with maximum results.

Over time, every internal combustion engine builds up carbon on parts like intake valves, pistons, and the EGR system. This build-up leads to:

Sluggish performance

Poor fuel economy

Increased emissions

Long-term wear and engine stress


Our mobile service helps restore your engine’s efficiency and performance — at your home or workplace, with zero hassle.

🔧 Why Do Engines Build Up Carbon?

Incomplete fuel combustion leaves behind carbon residue

Modern fuels often burn less cleanly

Short journeys and idling make it worse (especially in diesel engines)

Affects performance over time even in well-maintained vehicles

⚙ How the Process Works

1. Diagnostic Check
We scan your ECU to check engine condition, identify any faults, and ensure safe operation.


2. Hydrogen Cleaning Process
Hydrogen gas is introduced via the air intake while the engine idles. It reacts with carbon deposits and breaks them down into harmless gases that are expelled through the exhaust.


3. No Chemicals. No Dismantling. No Risk.
Safe for all diesel and petrol engines — including hybrids, vans, motorbikes, and performance cars.


✅ What You’ll Notice After the Clean:

Smoother, quieter engine

Improved throttle response

Reduced smoke and emissions

Better MPG (fuel economy)

Lower risk of engine issues or DPF problems

🧰 Ideal for:

City drivers • Diesel cars & vans • Turbocharged engines • Preventive maintenance
One service can make your engine feel like new.

Enhance Your Vehicle’s Performance with Gearbox (TCU) Remapping

If you want sharper acceleration, smoother gear changes, and a transmission that truly matches your engine’s power — a TCU remap is the perfect upgrade.
At BitPerformance, we specialize in unlocking the full potential of your automatic gearbox, directly at your home or workplace.

🔧 What Is a TCU Remap?

The Transmission Control Unit (TCU) controls how your automatic gearbox shifts. With a remap, we reprogram the gearbox software to:

Increase shift speed and smoothness

Raise torque limits (especially when paired with an ECU remap)

Enhance throttle and low-speed response

Improve manual paddle shift reaction

Optimize torque converter behavior

And in some cases – even reduce fuel consumption


Whether you drive a DSG, ZF8HP, S-Tronic, Tiptronic, or 7G-Tronic gearbox — we tailor the remap to your vehicle and driving style.

🚗 Why Don’t Cars Come Tuned from the Factory?

Manufacturers often use the same gearbox hardware across multiple models but restrict performance through software — to create “model separation” and meet market targets.

For example:
A VW Golf DSG gearbox can be the same unit as one in an Audi S3 or RS3, but the shift behavior and torque handling differ entirely — all due to TCU software.

With our remap, we unlock that factory-hidden potential.


✅ Benefits of Gearbox Remapping

✔ Faster, smoother gear shifts
✔ More aggressive or refined drive feel (your choice)
✔ Better paddle/manual shift control
✔ Early torque converter lock-up for smoother take-off
✔ Reduced power loss = better fuel economy
✔ Fully personalized mapping based on your vehicle and goals

> 📌 Note: A gearbox remap does not increase fuel consumption. In fact, smoother shifting can help improve MPG in urban and highway driving.
