Professional Mobile ECU Remapping in Manchester
Welcome to Dark Peak Performance, Manchester’s premier mobile ECU remapping and vehicle diagnostics specialist. We bring professional tuning services directly to your home or workplace, covering the entire Greater Manchester area.
Your vehicle’s Engine Control Unit (ECU) is a small computer that controls how your engine works. Manufacturers often set this software to conservative levels to account for poor fuel quality in other countries or to create "lower power" versions of the same engine for marketing purposes.
ECU remapping (also known as chips or software tuning) rewrites this software to safely unlock power, torque, and efficiency that was restricted at the factory. The result? A smoother, faster, and often more economical vehicle—without any mechanical changes.
Why Choose Dark Peak Performance?
There are many "maps on driveways" services, but DPP stands out for professionalism and safety. Here is why Manchester drivers trust us:
- We Come To You: Our fully mobile service saves you time. We operate across Manchester, Stockport, Tameside, Oldham, and beyond.
- IMI Certified: We are qualified by the Institute of the Motor Industry, ensuring we understand the complex mechanics of your vehicle, not just the software.
- Genuine Tools: We use legitimate, subscribed tools (e.g., Alientech, Autotuner) which provide stable, safe connections to your ECU. We never use cloned or fake equipment that risks "bricking" your ECU.
- Custom Files: We don't use generic files from the internet. Every remap is custom-calibrated for your specific vehicle ECU software version.
- Diagnostic-Led Approach: We always perform a full health check before writing any software. If your car has an underlying fault, we won't tune it until it's fixed. Your safety comes first.
Detailed Service Overview
We offer a range of tuning options tailored to your needs. Not sure what you need? Just ask.
Stage 1 Remapping
Designed for standard vehicles with no hardware modifications. Increases power and torque by 20-35% on turbo vehicles.
From £179
Economy & 50/50 Tuning
Optimised for fuel efficiency. Ideal for fleet vehicles, vans, and high-mileage drivers. Save up to 10-15% on fuel.
From £179
TCU / Gearbox Tuning
Faster shift speeds, torque limiters raised, and optimised shift points for DSG, S-Tronic, and ZF gearboxes.
From £149
DPF & EGR Solutions
Software solutions for clogged Diesel Particulate Filters and sticking EGR valves. Strictly for off-road use.
Stage 1 Performance Tuning
Our most popular service. A Stage 1 Remap is designed for a vehicle with stock hardware (standard exhaust, intake, etc.). By carefully adjusting parameters like boost pressure, fuel injection timing, and ignition advance, we can safely extract significant performance gains.
Benefits include:
- Increased Horsepower & Torque (typically +20-35% for turbo engines)
- Sharper throttle response (less "lag")
- Smoother power delivery across the rev range
- Safer overtaking capability
Economy & Fleet Tuning
With rising fuel costs, our Economy Remaps are increasingly essential for van drivers and commuters. By increasing low-end torque, we allow the engine to pull harder in higher gears at lower RPMs. This means you can change up a gear sooner and stay in high gear longer, significantly reducing fuel consumption.
Diagnostic Services & Fault Finding
Is your engine management light (EML) on? Is your car going into "limp mode"? Dark Peak Performance offers comprehensive diagnostic services. We don't just read the code and guess; we investigate the root cause.
We cover all systems including:
- Engine Management
- ABS & Traction Control
- Airbag & SRS Systems
- DPF & Emissions Systems
- Battery Registration & Coding
- Electronic Parking Brakes
Price: Diagnostics start from just £49. If you proceed with a repair or remap, this fee is often waived or discounted.
Our Safety Process
Safety is our priority. We treat every vehicle as if it were our own.
Health Check
Full diagnostic scan to ensure no underlying faults exist before we start.
ECU Read
We read your vehicle's current software via the OBD port or bench connection.
Calibration
Your file is custom-edited by our tuning partners (Viezu/Avon) for your specific needs.
Write & Test
The new software is written to the ECU, followed by a post-map diagnostic scan.
Test Drive
We verify the performance and ensure smooth operation on the road.
Frequently Asked Questions
Will remapping void my warranty?
Manufacturer warranties generally do not cover modified vehicles. However, our remaps are software-based and often undetectable by basic dealer diagnostics. That said, if a major engine failure occurs and the ECU is sent for forensic analysis, the modification could be found. We recommend waiting until your warranty expires if this is a major concern, though many customers choose to proceed regardless due to the high reliability of our maps.
Can you chip my non-turbo (naturally aspirated) car?
Yes, but the gains are smaller than turbo vehicles. Expect a 5-10% increase in power and sharper throttle response. The main benefit on non-turbo cars is purely drivability rather than massive horsepower figures.
Is remapping reversible?
Yes. We can restore your vehicle to the original factory settings at any time. We keep a backup of your original ECU software. If you wish to return the car to standard (for example, when selling it or returning a lease vehicle), we can revert it for a small service fee.
Do you come to me?
Absolutely. We are a fully mobile service. We need a safe place to park (driveway or work car park) and, ideally, access to a power socket (though we carry our own power supply for most jobs). We cover all of Greater Manchester.
Will my fuel consumption increase?
If you drive aggressively to enjoy the new power, yes, fuel usage may rise slightly. However, under normal driving conditions, many customers actually see an improvement in MPG because the engine doesn't have to work as hard to maintain speed.
What is DPF/AdBlue removal?
These are "off-road only" services. Removing emissions equipment makes a vehicle illegal for road use in the UK and will result in an MOT failure. We offer these solutions for export vehicles, track cars, or off-road machinery. We require you to sign a disclaimer acknowledging these legal implications.
