Rapid TPM: a new platform for cars with turbo-diesel and turbo-petrol engines
Rapid TPM (Turbo Power Management) is DIMSPORT's latest technological innovation. It is a new generation platform that is able to handle turbo-diesel and turbo-petrol engines. The new module is equipped with a microprocessor, FLASH eprom and RAM eeprom so as to gain full control of the relevant pressure sensors; these are also able to control some signals sent from the CAN BUS line of the vehicle's original electronic control units.
All Rapid modules were developed with a view to keeping unchanged the safety and protection features of the original engine control unit, such as the self-adapting functions of the vehicle's electronic system and the monitoring of critical parameters relating to engine function. Some wirings are already designed to work with communication protocol SAE J2716 SENT.
THE WORLD OF TURBO-PETROL
The world of cars has evolved giving new space to supercharged Petrol engines, which are increasingly common in small to medium-sized vehicles. The approach chosen for Rapid TPM allows for customised engine function, by analysing various signals such as air flow, intake manifold pressure, turbo pressure and engine RPM.
The platform is linked directly to the sensors with plug&play wiring, which is specifically designed for each compatible vehicle.
In the case of turbo-diesel engines, Rapid TPM works with the signal sent by the rail pressure sensor in a simple and efficient way; in addition to this, the pressure in the intake manifold can also be altered in order to manage the turbo, using engine RPM as well as any additional signals that may have been sent from the CAN line as a reference.
ONE SINGLE MODULE FOR ALL APPLICATIONS
TPM modules are the same for all applications: The choice of Specific wiring and the writing of custom-made firmware using the TPM Software, allows for the creation of a customised kit for the required application, with the added benefit of standard calibration provided by DIMSPORT and a professional tool for even finer tuning of the vehicle in real time.
The other Rapid modules
Besides the TPM platform, Rapid offers a range of successful products made exclusively for Turbo Diesel engines.
This product range is available for cars, commercial vehicles, trucks, tractors and boats. All modules were developed with a view to keeping unchanged the safety and protection features of the vehicle's original electronic control unit, such as the self-adapting functions of the vehicle's electronic system, the management of the diesel particulate filter and the monitoring of critical parameters relating to engine function.
ADJUSTING THE RAIL PRESSURE
The first approach (the Rapid LPI and LPT approach) makes it possible to personalise the function of the engine and fuel flow by calibrating the signal indicating the diesel fuel injection pressure in the rail differently.
The advantages are: incredibly easy installation thanks to fewer wirings and the overall optimisation of torque output.
MANAGING INJECTION TIMES
Recalibration of injector opening time (duty-cycle injectors) makes it possible to manage specific signals sent by each injector, thus obtaining a detailed record of injection times and the quantity of fuel injected. Modules are linked directly to the injectors with wiring created ad hoc for each compatible vehicle.
This approach involved the development of especially advanced modules, equipped with a microprocessor, FLASH eprom and RAM eeprom for full control of the injection parameters, leading to the creation of successful products such as BHV, XTI, LPD, VPE and many others. The result is a module that supports significantly enhanced vehicle performance even during multiple injections, for example pre- and post-injections necessary in managing the diesel particulate filters.
CUSTOMISATION USING THE CONSOLE
The digital calibration console makes it possible to modify Rapid's reference values, which determine the intervention threshold and the increase in torque and power, customising performance depending on the vehicle and what the requirements are. DIMSPORT provides a standard calibration for each application but additional fine-tuning can be made in real time, on the road or on the power test bench.
