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.

    Air Fuel Ratios

    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 pressurises 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.

    EGR Removal/Delete

    EGR Delete software can save you money in repairs and in fuel costs. Celtic Tuning are at the forefront of EGR Removal and EGR Bypass software and can correctly remove the functionality from the software of most ECU types. Some companies will simply turn off the codes associated with it being unplugged but this is not the correct way. The EGR valve needs properly disabling to ensure it is not trying to recirculate exhausts gases whilst still physically working in the engine.

    •   Restored Engine Power
    •   Restored MPG
    •   Cleaner emissions as faulty EGR’s create much higher soot deposits
    •   Can prevent DPF failure as the soot is caught in the DPF trap
    •   Can prevent EGR replacement which can cost hundreds of pounds
    •   Still 100% MOT compliant
