Radical Remaps Tuning OBD - ECU

For many years now, engines have been electronically controlled by an ECU (Electronically controlled unit). This is the vehicles brain and defines the ignition timing, fuelling, boost pressure and other engine running parameters. We can optimise these parameters to enhance the performance of your engine by reprogramming the factory ECU within your car.

An ECU Remap for a turbo engine typically produces 25% more power and 30% more torque dependant on the spec and condition of the engine. The increased engine power output will significantly give more throttle response, with more torque upon acceleration and reduced turbo lag throughout the entire rev range.

Key Points:

  • Significant Increases In Engine Power
  • Custom ECU Remapping From £200 Depending On The Vehicle Tuning Method
  • KTAG Bench Tuning
  • ECU Cloning
  • Huge Increases In Torque Throughout Your Engines Rev Range.
  • Increase Your MPG Helping You Beat Increasing Fuel Costs
  • Safer Overtaking And Much Better Towing Capability
  • Stage I, II & III Tuning Available
  • ECU Repairs & Postal Remapping Just Pop Your ECU In The Post
  • We Tune Your Vehicle For Life! It will Never Need Re-tuning Again
  • Full Diagnostic Check Before Any Work Carried Out
  • Speed Limiter Removal

Remap Stage 1 Eco

If you are looking for purely MPG gains then the green ‘Eco’ map is the option for you.

This option generally see’s an increase of 8 – 15% on MPG and is the more popular map we fit on taxi’s

Gains are dependant on vehicle condition and driving style

Stage 2: Economy & Performance

This option is the most popular of our remaps providing maximum uplifts in BHP and torque whilst retaining the 8 – 15% MPG increase from the Eco map

Helps to take away the lag found in modern cars when pulling away, gives sharper throttle response and provides more mid-range power for acceleration and overtaking

Perfect for any vehicle and an excellent choice for towing vehicles and for motorhomes

Stage 3: Full Performance Gains

This is our full power option, with maximum achievable gains in BHP and torque whilst staying in the green zone and not compromising your engine

Typically 10% more horsepower and torque than our stage II maps

Ktag Bench Advanced Remapping & Cloning

This is for when ECUs cannot be remapped on the car and requires the ECU to be removed from the vehicle and tuned directly to the circuit board on the bench. This normally takes 3-4 hours to complete this mode of tuning and can only be carried out at our tuning centre in Exminster. With this mode of tuning we can now access all parts /sectors of your vehicles maps this means a much better remap can be achieved!

With this method of tuning it is also possible to clone ECUs. This is where we take a damaged ECU and transfer the information on it to another unit resulting in a cheaper alternative to Main Dealer prices for replacement ECUs for your vehicle.

Prices for this range from £300-£450 depending on the level and type of work required. Please contact us for more details

All our ECU remaps come with a lifetime software guarantee. Additionally, if you do not experience any improvements stated we will tweak or adjust the file for you. We offer a seven-day money back guarantee on all our remaps. We also offer our customers a ‘Optional Extra’ this is our Mechanical & Electrical 12 month or 30,000 mile Break Down After Remap Warranty’ which gives you total peace of mind for qualifying vehicles.

Our philosophy is to provide our customers with the best possible aftermarket ECU tuning solutions for their vehicle coupled with outstanding customer service. We pride ourselves on giving our customers world leading ECU remapping solutions, giving you the performance advantage. Just look at our ‘Customer Testimonials’ to find out how our customers are enjoying the benefits that our ECU Remapping service provides.

After every remap we like to accompany you as you test drive your car. We believe the best way to show you our confidence in ECU Remapping is to be with you when you see the results for yourself. It’s this part that makes our job worthwhile, and we truly enjoy knowing you are 100% happy with the changes before any payment is taken.

Please feel free to ‘Contact Us’ if you have any questions or enquiries and don’t forget to include your vehicles registration number.

The Hidden Dangers! of Diesel Tuning and Remapping. A few things to Consider before Purchasing a Remap.

Radical Remaps guide to professional Custom ECU Remapping. I have included this information on our website due to the huge increase in our company repairing sub-standard Remaps. We our now repairing more and more Ecu’s due to cheap substandard remapping being carried out by so called professional remapping companies.

We normally repair 2-3 ECU’s a month because people are getting sailed down the river when it comes to Custom Remapping. Some of the work that we have seen lately has been unbelievably BAD. I will give you an example of a customer who contacted me and explained that he had his car remapped by a well known remapping company 2-3months ago and the vehicle seemed to be going into limp mode and loosing power and producing lots of smoke!

He explained that he had taken the vehicle to a diesel repair specialist to determine the problems they then started to try and eliminate the defects by changing different sensors, EGR Valve and so on. This was unsuccessful the problem still remained. We said that I would need to take a copy of the file that was installed on his ECU so we could determine if the Remap he had done was suitable for his vehicle.

We took the copy and found that the Remap had many defects that were, contributing to the bad running and performance of his vehicle. We found that the turbo boost was turned up, but the Turbo limiter was not adjusted! The Torque limiters where turned up to far as much as 45% to much. Fuelling was not adjusted the list went on. We had to totally Remap the vehicle so all of the problems where sorted out and we put the ECU software back to the tolerances to suit the vehicle CUSTOM REMAPPING.

The up shot of the above example is that the customer had to spend more money trying to chase down the problem by changing sensors and so on, with no success he had to pay for another Remap as well. The original price for the sub-standard Remap was £200. The cost of changing engine parts £550. The cost of our custom Remap fix was £275 the total cost is you can see was very expensive.

There are many other examples but I hope that this information will help you the customer to make a informed decision and choice before you Remap your vehicle by someone that is just too cheap! A normal Custom Setting file price for a given vehicle can range from £100 to £160 this is the cost to any legitimate tuner before they do any tuning. The setting file gives the tuner access to the vehicles ECU. So if someone quotes you £100 – £150 for a full custom Remap there is something wrong!! Given the ‘Setting File’ costs, advertising costs, fuel costs £150 will not pay for the latter. So how do they get around this, well its easy give the customer substandard re-used maps thus negating the setting file cost, now he is in profit of £100-£150.

What is a Setting File? ‘ECM Titanium’allows the user to work on injection, ignition (real degrees of advance), boosting parameters, correction maps, rev./speed limiters avoiding problems tied to map locating. This is possible by the “SETTING FILES” which locate the data set areas containing all the important parameters controlling the engine workings

It is prudent to ensure you are getting good backup and after sales support. Simple things such as:

  • 7 day no quibble trial period so you can test in your own time.
  • Lifetime warranty on the product against corruption or other defect.
  • A Optional Comprehensive Machanical & Electrical after remap Warranty.
  • Easy access to your original calibration file if you need it.
  • Fuel economy improvements guaranteed if turbo diesel powered.

Finally, your installer should be able to give you the telephone number of the actual file calibrator if it isn’t himself.

That way you can call him and get some information as to their credentials. Please take care out there… don’t be the next customer whom comes to us to get their ECU working properly again after someone has damaged it with cheap tools, ECU tuning inexperience and Cheap re-used files.
