Diagnostics/Performance Tuning
Modern vehicles are ever increasing in complexity and the need for specialist equipment and knowledge is growing accordingly.
We specialise in offering dealer level diagnostics and fault finding without the dealer level prices.
We carry dealer level tooling and have access to all of the latest technical data, wiring diagrams & technical bulletins and this allows us to carry out a professional and competent diagnosis and repairs on german vehicles.
Before booking in for diagnostics can you supply us with as much information as possible such as:-
Does the problem only occur when the car is hot or cold?
Are the warning light intermittent?
The more information we have, the more promptly and accurately we can diagnose the fault.
We hope you will find the information you need on this site
in addition, look forward to being of assistance to you.

“A recent upgrade carried out on a BMW 530D 2004 E60, showed an increase of 30bhp. The maximum torque increased by 35lb/ft to 405lb/ft. However, the largest gain was a staggering increase of 54lb/ft @ 3200rpm.”
Mike Collen, Managing Director, Diagnos.co.uk Ltd
The benefits are evident: more power, more engine flexibility and increased fuel efficiency; an attractive combination. Petrol upgrades show more torque, smoother throttle response and speed limiter removal.

Performance tuning
Diagnos has developed tunes for all of the control units listed above. There are however hundreds of variations for each control unit and vehicle. It is necessary therefore, for you to diagnose the vehicle with Autologic and determine whether or not –
• A performance tune exists for the current level of ECU software
• Diagnos are required to develop a Performance Tune for this variation
If a tune does not exist, we can send specific data about the control unit to diagnos. New Performance Tunes can be written and uploaded to the dianos.co.uk website usually within 24 hours
For engine control units that are "flash programmable", Autologic offers the advantage of performance tuning (also known as chip tuning). Autologic Performance Tunes are modifications to the manufacturers’ vehicle tune data, designed to improve engine and running performance. These performance tunes are downloaded to the vehicle`s ECM from the Autologic through the on-board diagnostic connector. Performance tuning with Autologic can usually be carried out on a vehicle within one hour while the customer is waiting.
• Increased power and torque
• Smoother delivery of power
• Increased fuel economy
• in most diesel
• applications
• Sharper throttle response
• Faster acceleration
• Reduced number of gear changes
All upgrades are through the diagnostic connector, meaning that the ECM does not have to be removed and opened up
