When increasing the fuelling and boost pressures of an engine it naturally increases the EGT. A spike in the boost delivery can cause over-boosting which pressurises the compressor to a level beyond its tolerance. 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. This is also important in ensuring that your engine is MOT compliant. This in basic terms means that the engine isn’t running lean or rich fuel mixture. It is important to ensure optimum AFR is achieved in order to ensure that stoichiometric mixture. 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.Īll of our software is dyno developed and logged to ensure engine parameters are accurately monitored for the following: 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.

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. As electronics have advanced further, the latest generation of ECU’s have what is referred to as a locked TriCore processor. They are essentially exactly the same thing, only OBD port remapping is less intrusive and requires no removal or opening of the ECU. 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. altering the standard software within a chip.

The software inside the chip is what is referred to as remapping, i.e. Chip tuning requires the removal of the Eprom from the ECU and the software is programmed to the chip on the bench. A Celtic Tuning super chip can provide you with all stages of upgrade from basic ECU Remap right up to full engine conversions.Ĭhip tuning is the original definition of what modern day ECU Remapping has become. At Celtic Tuning we write/develop our own software in house which gives us endless flexibility to provide you (the customer) with the exact results you are looking for from your ECU Remap.
