The TDI Engine

TDI-RemapThe term TDi stands for “Turbo Diesel Injection” and references the type of diesel injection method used. The early TDi engines used a Pumpe Düse injection system which had pressures of 2025bar constant. They provided for great power and delivery but as more stringent emission regulations have come into place this method has proved too dirty and unrefined to move forward with. As a result the VAG group have moved to Common Rail technology 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.


A TDi Remap from Celtic Tuning can completely transform your TDi engine and revolutionise your own driving experience. The introduction of modular engines and the huge leap forward in electronic control has meant that a TDi 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.


2010> VW Transporter 2.0 TDI runs a Bosch EDC17CP20 engine management system and comes in 84bhp, 102bhp, 140bhp and 180bhp formats. They all share the same basic block engine which has a factory torque output of 295lbft… the only difference being the 180bhp has a twin turbo setup. The 84bhp, 102bhp and 140bhp have 100% mechanically identical engines with the only variance being the software. They run the same injectors and turbo systems throughout these variants and as such we can take the 84bhp up to a factory 140bhp without going outside factory tolerances.

TDI Fuel Economy

Having your TDI Remap with Celtic Tuning will not only increase the power of your engine it will also provide you with great gains in fuel economy. The key to fuel economy is fuel pressure and torque delivery which is how modern diesel engines are achieving such impressive figures. A Celtic tuning TDI Remap optimises fuel pressure points and torque delivery to ensure that under general driving conditions you will see a nice improvement in fuel economy.
