trusted tuners

Avon Tuning

Avon Tuning was founded in 2010 by the owner and current technical director Gareth Jones. Initially Avon Tuning was completely focused on ECU Remapping and performance tuning, however over the years the company has evolved quite dramatically and we now offer a range of technical services, these services can be divided into four main categories.

ECU Remapping

Unleashing the true potential of a vehicle, depending on customer requirements this could be simply to extract as much performance as possible or to generate the most amount of fuel efficiency. All our maps are fully custom and most are developed in house on our Dynocom 5000 series rolling road. We cover all sectors, Automotive, HGV, Agricultural, Marine.

Vehicle Modification

We try to develop solutions to bypass the often unnecessary components and features installed on modern automotive vehicles. This can be for performance reasons or simply as a more cost effective solution to replacing a faulty component. E.g. Bypassing the EGR system to improve fuel efficiency and reduce maintenance costs.

DPF Solutions

We have a vast amount of experience with the often miss understood DPF systems on modern diesel vehicles and can offer a wide range of services depending on the customers’ requirements. From cleaning, to removal, to replacement, we offer a professional solution to suit your needs.

Diagnostic and Programming

Continued investment into the latest aftermarket and main dealer diagnostic equipment allows us to offer everything a dealer can and more. Often our tools can access a level of computer interrogation that even the main dealers can only dream of. From fault finding to module programming and initialization we have the equipment, knowledge and training.

Our facility

We have a 5000 square foot dedicated workshop located in a small village called Tockington on the outer skirts of North Bristol, very close to the M4 and M5 interchange. Within this workshop we carry out all DPF related work, ECU Remapping, diagnostics and vehicle modifications. We also have a sister company located in Hewish – Weston-super-Mare, who can carry out the more mainstream garage services (Avon Auto Clinic). Our Dynocom 5000 series rolling road is located in our Bristol workshop, this dyno is predominately used for research and development work and along with custom tuning.
