Performance Remapping

Contact us to see how Turbo Dynamics and Celtic Tuning can help increase your performance - mapping@turbodynamics.co.uk

Celtic Tuning are specialists, through development and reverse engineering, in the performance tuning of most modern vehicles. With all manufacturers now turning to modular engines to ensure maximum cost savings and economies of scale, it has ensured even greater tolerances are available in the engine units. The basics of this are they now produce fewer engines to keep design and manufacturing costs down and use software to provide varying levels of power outputs to satisfy the various markets. Due to our experience with tuning vehicles, where requested, we can also provide custom tuning whereby we are able to accommodate larger turbos, injectors etc as well as remove speed limiters and raise rpm limiters etc.

Chip tuning is the original definition of what modern day ECU Remapping has become. Chip tuning requires the removal of the Eprom from the ECU and the software is programmed to the chip on the bench. The software inside the chip is what is referred to as remapping, i.e. altering the standard software within a chip. Chip tuning or chipping has become less and less prevalent in the market place as, since 1996, OBD remapping has taken its place enabling remapping to be done via the OBD (on-board diagnostics) port. They are essentially exactly the same thing, only OBD port remapping is less intrusive and requires no removal or opening of the ECU. As electronics have advanced further, the latest generation of ECU’s have what is referred to as a locked TriCore processor. This in basic terms has removed the ability to flash software via the OBD port and the only method available is to open the ECU and remap via direct connection. It is much less invasive than chip tuning as you do not remove the Eprom, the only downside is opening of the ECU for warranty purposes.

We work on all ages of ECU from the early EDC's requiring chip tuning right the way through to modern MEDC17 locked tricore processor ECU's with tuner protection. A Celtic Tuning superchip can provide you with all stages of upgrade from a basic ECU Remap right up to full engine conversions.

All of Celtic Tunings software is dyno developed and logged to ensure engine parameters are accurately monitored for the following:

Air Fuel Ratios (AFR’s)
It is important to ensure optimum AFR is achieved not just for performance-tuning reasons but also for reduce pollution (greener) and better economy. This, in basic terms means that the engine isn’t running a lean or rich fuel mixture. This is also important in ensuring that your engine is MOT compliant. The optimum state, known as stoichiometric mixture, is achieved when there is just enough air to burn all of the fuel supplied.

Boost Pressure
It is important that correct boost pressure control is achieved to ensure that no spikes or dips occur to ensure maintained life of the turbo charger. A spike in the boost delivery can cause over-boosting which pressurises the compressor to a level beyond its tolerance. The turbocharger rotor overspeed can cause excessive thrust loading and take the compressor to a level beyond its tolerance.

Exhaust Gas Temperatures (EGT)
When increasing the fuelling and boost pressures of an engine it naturally increases the EGT. It is important to log the EGT of an engine as there is a crucial limit which shouldn’t be surpassed to ensure maintained longevity. This is a good tool in monitoring the efficiency of uprated intercoolers etc.

Injector Duty Cycles (IDC)
This is crucial to know the fuelling limitation of the injector. On some modern cars we are seeing injectors with 100% IDC from standard meaning there is no room for further modification without upgrading the injectors (this is rare however). If it was a turbo application, and the boost pressure was raised, due to there being no additional fuel available, it would cause the engine to run lean and potentially melt your pistons.

As a result of fine monitoring and adjustment to their software, the Celtic Tuning superchips are able to provide safe and reliable tuning for both performance and economy. We will not operate outside of the engines capabilities on standard components as your vehicles reliability is as important to us as it is to you.

All of the software comes with a 14 Day full money back guarantee, a lifetime software warranty and for those vehicles under 3 years old and less than 60,000 miles we also provide an insurance underwritten mechanical breakdown cover so you know with TD and Celtic Tuning your car is in safe hands. Terms and conditions apply.
