Indeed, in the '90s, everything changed in terms of engine chiptuning in cars. You probably have already grasped the reason, but let's take a look at the fundamental steps and how the advent of electronics opened new doors to tuners.
The new SUV is named Grecale. Usually, we don't delve into dimensions, but today we'll make an exception, recalling the measurements of this sporty model: it is 485 cm long, 198 cm wide, and 166 cm tall. It uses a variant of the "Giorgio" platform (also used by the Alfa Romeo Stelvio but without common components), features vertically developed headlights, and lines reminiscent of the MC20.
The XPF Emulator operates by connecting to the car's stock exhaust system sensors through a dedicated wiring harness. This ingenious emulator sends precise reference signals to the electronic control unit (ECU), simulating the perfect operation of the particulate filter itself.
When it comes to tuning cars, practices aimed at increasing torque and, consequently, engine power, whether fuelled by diesel or gasoline, are often discussed in a very general manner without specifying the main aspects to consider. In this article, we will try to shed light on the most important aspects (or at least the main ones) that can be addressed to enhance the performance of an automotive engine.
In the '90s, there were a series of innovations regarding diesel injection systems. We transitioned from purely mechanical rotary injection pumps to electronically controlled rotary injection pumps (similarly for less common inline pumps). Then came radial piston injection pumps with a complex electronic control system based on CAN, PDE injection systems (pump-injector elements), and towards the end of that decade, common rail systems became wide
