HDI Remap

The HDI Engine

The term HDi stands for “High Pressure Diesel Injection” and references the type of diesel injection method used. A HDi engine is a common rail engine which runs at pressures up to 2,000 bar (29,400 PSI) and can inject up to 7 times per cycle per cylinder. The fuel is delivered to all injectors by one fuel rail “Common rail” and is electronically controlled for upmost precision of injection timing. The modern common rail diesel engine can inject up to 7 times per cycle and has been the key to current refinement and economy standards.

HDI ECU Remap

A HDI Remap from Celtic Tuning can completely transform your HDI engine and revolutionise your own driving experience. The introduction of modular engines and the huge leap forward in electronic control has meant that a HDi remap can exploit the potential in your engine whilst staying within factory tolerances. Manufacturers use this same technique to vary the output of engines that they provide you with to save on costs and maximise profits.

Example:

2012> Peugeot Partner Van runs a Bosch EDC17C10 engine management system and comes in 75bhp and 90bhp formats. The 75bhp is simply a factory detuned version of the 90bhp and as such we can make the 75hp a factory spec 90bhp by altering the software alone. We can therefore take the 75bhp to the same maximum power output as the 90bhp with the same level of tolerances.
