Let's discuss the 418d version F32-33-36-82-83. Sorry, with all due respect, who advised you to buy a 4-Series with this engine configuration? We understand those who don't want to choose the 3000 turbodiesel versions or even more so those who are frightened by the M4 (450 horsepower) and M4 GTS acronyms, but going " under" the 2-liter common rail 184hp seems risky when talking about BMW 4 Series.
Welcome back; we have returned (as promised) to discuss in detail how chip tuning units work on diesel engines that use PDEs, or injector pumps, as their injection system. We previously described other injection systems, namely, the first electronic injection control system via an electronically controlled rotary pump, then the second evolution of centralized injection pump, i.e., the one with a radial piston pump.
The Jeep Compass 1.6 multijet 120hp is a car that has found a fair amount of success. It's available with an array of different engines, but today we are talking about the diesel 1600 that uses a customized version of the Fiat-derived 4-cylinder common-rail, with four valves per cylinder and 120hp maximum power.
This is the W222 version produced since 2013, with a nice 3-liter common-rail V6 engine that has a lot of new technology in its engine management and power supply. The engine is one of many variants of the 2987cc with 6 V-cylinders, four valves per cylinder, a variable geometry turbocharger placed between the cylinder banks, and an intercooler.
These pumps already had some electronics built into the mechanical body, from which four wires led out to two solenoids controlled in PWM by the same electronics. The control of the injection pump by the ECU (at least in the more complex versions) was handled via CAN-BUS (Controller Area Network). This was a standard bus protocol used predominantly in the automotive field. We have two additional chip tuning models for this type of pump.
