Frequently Asked Questions

What is ECU remapping?

An ECU remap is the fine tuning of the program that deals with your engine’s performance and management. As well as achieving greater power and torque by remapping we also deal with drivability problems that occur within lower rev ranges, such as flat spots, turbo lag and hesitation issues, giving the engine more initial torque, which makes for a more responsive and enjoyable drive.

How much power will I gain ?

No two cars are the same, so a ‘uniform’ end result cannot be predicted to absolute precision. We guarantee to provide the largest achievable increase in BHP within safe parameters, which varies from engine to engine. As an approximate guide, you can typically expect an ECU remap from Advanced Tuning to result in power increases in the regions of;

  • Non turbo petrol or diesel – upto 10-15%
  • Turbo petrol – upto 20-30%
  • Turbo diesel – upto 20-40%

What warranty do you provide ?

Any software installed on your vehicle by Advanced Tuning is covered by a lifetime warranty.

How will remapping effect my MPG?

As with power increase estimates, specific figures are difficult to estimate, as no two engines or driving styles are the same. Usually, petrol engines do not see an MPG gain from remapping, unlike diesel and turbo diesel vehicles, which – if driven normally with economy in mind – can see upto 20% improvement in MPG following our fine tuning*.

Other factors such as incorrect tyre pressure and fitted roof storage products can adversely affect fuel consumption. We also would recommend purchasing fuel from a recognised brand outlet such as Shell, Texaco or BP as opposed to supermarket fuels as the diesel contains a small percentage of biodiesel which lowers the cetane rating of mineral diesel and the petrol contains ethanol to act as a dilutant.

*Based on actual customer feedback.

Will the ECU remapping damage my car?

The plain and simple answer to this is ‘no’. We never use generic ECU remapping files and always custom design a map tailored to suit your vehicle specifically. We also never over-stress components or sacrifice the reliability for a few extra BHP.

Do you have a rolling road dyno?

Yes we do, it is used constantly for research, development and refinement of ECU maps for existing vehicles and new models not yet in our current portfolio.

Do I to come to you to have it done?

We have dealers covering locations all over the UK. If you don’t see your location covered in our listed areas, don’t hesitate to get in touch.

Do I need to inform my insurance company?

We would never advise anyone not to inform their insurance company. However our ECU remapping processes are undetectable by virtually all dealer diagnostic equipment. Furthermore over 90 percent of insurance companies won’t add an extra premium so the decision is entirely at your discretion.

If I have specific requirements can you help?

We tailor our ECU remapping to suit individual engines and in most cases we can remap your car to suit a specific driving style or need. Whether this is more torque for towing purposes, more power for off-road use.

How long will it take to carry out?

To complete, the ECU remapping process should take no more than one hour for remapping through the diagnostic port. To be absolutely sure, please allow up to two hours for the work to be completed in full.

My car has an automatic gearbox

We can still remap your vehicle even though it has an automatic gearbox. It does not affect the process, the time it takes or the end result.

My car is high mileage?

High mileage makes no difference providing the engine and its components are in good mechanical condition.

Is ECU remapping reversible?

ECU remapping is totally reversible. at any time you desire – we maintain a copy of your original vehicle map on our secure database. What’s more, Advanced Tuning’s experienced technicians will be happy to carry out the work required to restore your vehicle to its original settings and back to remapped for a reasonable charge.

Are there any hidden charges or costs?

Absolutely not. The price that you are quoted on the day of your booking is the price you’ll pay for your remap.
