The Jeep Compass SUV has just received a major power and torque boost thanks to a new Dieseltronic tuning box from Race Dynamics, a Bangalore-based company that builds performance enhancing accessories for both cars and motorcycles. The tuning box pushes up power and torque numbers of the Jeep Compass Diesel’s 2-litre Fiat Multijet turbocharged engine by about 15%. Race Dynamics has also put out dyno charts that show the exact quantum of power and torque increase due to the diesel tuning box. The stock Jeep Compass makes about 134 Bhp-280 Nm (at the front wheels), which is a lot lesser than the claimed figure for the 2-litre Multijet engine: 170 Bhp-350 Nm (measured at the crank).
After adding a Race Dynamics Dieseltronic tuning box, these outputs (at the wheel) have been enhanced to 151 Bhp and 320 Nm, which is a significant increase indeed. The tuning box can be installed quite easily by any competent mechanic, and it connects to the fuel rail of the engine.
It works by fooling the engine’s Electronic Control Unit (ECU) into thinking that the fuel pressure and turbo boost is low for a given throttle opening. This makes the ECU compensate by injecting more fuel into the engine, which is the reason why power and torque get significant boosts. The dual channel Dieseltronic tuning box for this particular Jeep Compass is priced at Rs. 26,000.
Those wanting to buy the Dieseltronic tuning box for the Jeep Compass must remember that tuning boxes can void warranty if detected by service centres. Generally, owners who use such tuning boxes disconnect them and remove them from the car before dropping off the vehicle for service.
While diesel tuning boxes do increase performance significantly without major engine damage, there’s always the possibility of the engine lasting about 10-20% less than the stock engine. This is a compromise that comes with every major performance enhancement for the engine. Usually, diesel engines last for at least 2-3 lakh kilometers, which means that most owners won’t even notice the slightly lower overall life of the engine.
