Frequently Asked Questions

What is An ECU?
The Engine Control Module (also called the Powertrain Control Module or PCM) is the brains of the engine management system. It controls the fuel mixture, ignition timing, variable cam timing and emissions control. It constantly monitors emissions performance via its OBD (Onboard Diagnostics) programming, and it oversees the operation of the fuel pump, engine cooling fan and charging system. It also interacts with the transmission controller (if separate), ABS/traction/stability control system, body control module, climate control module and anti-theft system. In short, the engine control module performs a wide variety of functions that are necessary to operate a vehicle.

Do you do custom tuning?
There is a lot confusion about custom and generic files, many of our competitors use the word Custom as marketing without really knowing what it means or if they do know they are simply lying to promote their business.
Our remaps are custom to your vehicle as in that we take a read of your ECU as this is tailored specifically to your vehicle and we then modify this data changing only the neccasary parts of data.
However strictly speaking these are Generic files that are tried, tested and proven calibrations, there is no need to reinvent or change something that is already proven to work
successfully time after time, but this is no different to what would happen if you went to a tuners with a rolling road / dyno facility, they would still use their last proven tune and demonstrate the gains on the dyno.

We know for a fact that tried, tested and proven is much better than an unproven custom tune stab-in-the-dark.

A real custom tune would set aside best part of a day on the dyno and take a known good baseline. Then using the dyno, AFR meter, boost gauge and obd2 logging data, etc. to progress the file, with multiple revisions to suit the vehicle setup, is this what you’ve been sold and if not it’s not Custom.

In summary, quality generic files are not a dirty word but actually favourable if you’re looking for safe additional power and drive-ability.

Why don’t vehicle manufacturers tune their vehicles?

Vehicle manufactures are in a tough position here, they have to build one cost effective vehicle for all drivers, taking into account tax banding, insurance, performance, price and economy, gone are the days when if you wanted more power you bought a vehicle with a larger engine. It’s just not economical for manufactures to design and develop new engines for each model in the range or necessary in this modern age.
A good example of this is the Ford Transit van utilising their 2.0 TDCi Engine, the vehicle is available with 3 x power options, 105 PS, 130 PS and 170 PS, the only difference is the map within the ECU, oh and the price.

And surprisingly, many manufactures do offer ECU remapping services, Volvo for instance allow main dealers to remap their vehicles under the Polestar badge, and Mercedes under Brabus.

Will a Remap invalidate my cars warranty?
A car remap will void your engine’s warranty (including the turbo or supercharger), and it may also void your clutch and gearbox warranty too. If you have heard different elsewhere, then you’ve been lied to. Car manufacturer warranties clearly state that modifications to any components that are not approved by the OEM will void their warranty.

A car remap not approved by your OEM falls under this.

If your car is still under warranty, then, you should definitely consider this – especially if your particular car has had to have warranty work carried out on the engine before, as your car will be at a heighted risk of needing further maintenance in the future. Of course, your car may need no warranty work carrying out at all. In this case it doesn’t matter if you have had a car remap. But, it’s a risk if your car still has any significant warranty on it.

Why do prices for remapping vary so much?
We only utilise the very latest tools and software , you should always insist that the tuner uses genuine tools and that they are in licence, a cloned or fake tool has no technical support and there is no back up should the worst happen.

Our maps are bespoke dyno proven files for your vehicle made, nothing is left to chance, their remap and ecu mapping R&D is the most serious and dedicated in the ecu mapping and chip tuning industry bar none, always ask the source of the map.

Why do power claims vary so much from tuners for a Stage 1 map for my vehicle?
You will see that the top companies within this sector all have developed maps producing very similar gains. Beware of tuners who claim significantly more, it’s either being economical with the truth relying on that the customer will not notice to win the business, or the engine and components will be pushed too hard and become unreliable.

How is the tune carried out?
Note: For safety reasons we only work on vehicles are that are capable of being tuned via the world standard OBD2 port as this is still the most secure way to carry out remaps, the steps are as follows:

1. An engine diagnostic check is undertaken and any fault codes cleared prior to starting the remap, as a customer you will be advised of any issues.
2. An battery stabilisation unit is attached to your vehicle as it’s critical to maintain voltage during the process.
3. A full copy of your existing ECU’s software is made, labelled carefully, backed up and stored for easy access.
4. A copy of your file is sent off to the tuners to modify to give the desired improvements to your vehicle’s power, torque and fuel economy.
5. The new map is uploaded to your ECU to transform your vehicle’s performance.
6. We carry out another diagnostic test to ensure that there are no fault codes present.
7. We hand you your keys and invite you to go for a drive and experience the transformation of your vehicle..

Is Remapping my vehicle safe?
Modification of vehicles is not without its risks, particularly when it is older, or driven to its limits constantly, inevitably there will be occasional serious failures as parts can and do fail when reaching the end of their useful life and very rarely is the failure due to the map itself.

However we do try to mitigate any risks as our goal is not how much additional power can be attained, but focused on delivering improved power and torque, to a comfortable point between what the engine and transmission can safely handle whist factoring in issues like exhaust gas temperatures, emissions, etc.

For peace of mind we do offer a 12 month mechanical breakdown warranty for eligible vehicles.
