Most turbo diesel vehicles and some turbo petrols will see an improvement in fuel efficiency after a remap. This may be up to 20%* for turbo diesels and up to 10%* for turbo petrols. Please feel free to discuss this when you contact us.

Renault CLIO 1.5 dCi Diesel ECU Remap Methodology

The process takes around 2 hours and in most cases is carried out by simply connecting our equipment to your Renault CLIO 1.5 dCi’s diagnostic port.

Firstly, we download a copy of the software from your Renault’s ECU. We keep a backup of this original software on our Amazon S3 Cloud servers.

Next, we test drive the vehicle with you so that we can check that there are no obvious reasons why your Renault CLIO 1.5 dCi shouldn’t be remapped. We can run generic diagnostics at this point if required. Once this is complete, we carry out the process of creating the new software version and then upload it into your Renault CLIO 1.5 dCi’s ECU.

Finally, we test drive your Renault again with you to make sure that you (and we) are happy with the results.

The new software for your Renault CLIO 1.5 dCi Diesel ECU Remap will be custom written, by our own file writers, using the original file that we copy from your vehicle as a unique starting point. This ensures that all vital vehicle data are retained and that the new software is tailored exactly to your vehicle’s existing settings and to your requirements.

Most Renault’s do not require any removal of parts to carry out a remap, but very occasionally we do have to remove an ECU and carry out the work directly on the ECU itself. In this case the job will take a little longer. Your technician will advise on this at the time of booking.


Pricing is worked out on a per vehicle basis and varies slightly between vehicles so please call or email for exact details.

Our prices are very competitive, but we are not bargain basement tuners tuners.

Our software is premium quality and custom written for each Renault CLIO 1.5 dCi individually. This is reflected in our (very slightly!) higher prices.

Quality: An Important Question

If you buy a Renault CLIO 1.5 dCi remap or tune from eBay or a franchise chain, you can save maybe £25 to £75. OK, this is a reasonable amount of money, BUT:

Is it worth risking the reliability of your Renault to save such a relatively small amount of money? Or would you rather have your Renault’s engine management software upgraded by a master tuner?
