JTD Remap

The JTD Engine

The term JTD is FIAT’S internal name for the “Turbo Diesel Common Rail Injection” engine and references the type of diesel injection method used. A common rail engine 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.

JTD ECU Remap

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

2008 Alfa Romeo GT 1.9 JTDm runs a Bosch EDC16C39 engine management system and comes in 150bhp and 170bhp formats. The only difference between these two variants is the software as the engines are 100% mechanically identical. So the 150bhp JTDm we can remap to either a Stage 1 factory 170bhp or the Stage 2 fast road.
