Take a copy of the file in your engine ECU

First we take a read of the current file in your engine ECU which will have all the performance parameters stored within.

the file gets tuned to your requirements

The file then gets sent to our tuning HQ where the work is done to implement your required adjustments to performance.

write the new file back onto your ENGINE ECU

Once we have recevied the file back, we will then write the modified file back to your ECU for you to enjoy the improvements.

What we can do for you.

It is not just out and out power that we can deliver…

Power, Half/Half & ECO Tune Remaps

Power & Performance remaps do exactly that. We can release the full capabilites of your petrol or diesel vehicle without any mechanical modifcations.

We can also offer either a mix of power and economy in turbo diesel engines or a slightly reduced power option to return an improved economy, again in turbo diesel engines.

Automatic Transmission Remaps

If your vehicle we are remapping is an automatic, if it has a DSG or S-Tronic twin clutch gearbox we recommend that we remap the gearbox to both accommodate and make the most of the increased output from the engine with a faster gear shifting speed.

DPF & EGR Solutions

The DPF is a filter in the exhaust system of modern diesel cars which can block up. We are able to offer a number of options to fix any DPF issues.

The EGR valve recirculates a proportion of the exhaust gasses back into the intake system. This valve can become clogged and lead to a loss in performance.

AdBlue Solutions

AdBlue is a fluid that has been used in vehicles since 2011. These systems are prone to failure as the AdBlue fluid is predisposed to crystallise in the tank, pump, lines and injector.

We are able to provide a number of options to resolve any AdBlue issues your vehicle may have.

VW/Audi/SEAT/Skoda ECU Emissions Update Software Rollback

The emissions update performed on vehicles by manufacturers puts excess strain on your engine’s fuel, emissions control and exhaust systems, making the engines run rougher and use more fuel.

We are able to roll back your ECU software in addition to your remap or in isolation.

Fault Code and failed component deletion.

Sometimes there are components that can fail on modern cars that will illuminate the engine management light. The most common we see are manifold swirl flaps, which can cost thousands to replace.

As an alternative, we are able to offer fault code and component deletion, which will mean the management light does not come on, and the car can continue to be used.

Client Testimonials

Don’t take our word for it – here’s what our clients say:

5 Stars for MapTune.co.uk

Exactly what I wanted. I spend a lot of my time on motorways and wanted a bit more grunt for overtaking and a bit more economy on the cruise.

Got both. Much nippier and I get 7mpg more.

James Usher

Audi A4 2.0 TDi

The swirl flap mechanism on my A6 had worn out and the repair kit plus fitting would have cost a fortune.

Went for a power remap and had Martin delete the swirl flaps. Now my 2.7 goes like a 3 litre and no engine light.

C Nield

Audi A6 2.7 TDi

I just wanted my car to feel a bit more sprightly when I drove it as it was the lowest output model Ford did in the range so I got the benefit of lower tax. I opted for the power remap and the car is transformed.

Peter Bond

Ford C Max
