Performance Diesel and Petrol Engine Tuning – ECU Remapping

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 has become less and less prevalent in the market place as OBD remapping has taken place enabling remapping to be done via the OBD 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.

All of our 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 in order to ensure that stoichiometric mixture. This in basic terms means that the engine isn’t running lean or rich fuel mixture. This is also important in ensuring that your engine is MOT compliant.

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 pressurizes 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 up rated 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 our super chip, we are able to provide safe and reliable tuning solutions to both customers and other tuning companies.  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.

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.
