So many loyal D4d steeds we’ve helped on their way to greatness over the past year or two, what we always see is there’s definitely a large correlation to the injector wear and bad power with these older model D4d’s!!
With the diminishing power levels comes bad fuel consumption which can be expected with Turbo diesel vehicles… To explain the efficiency of modern turbo diesel engines we have to solely look at the fuel injectors as they control fuel, timing and response of the vehicle!!
Atomizing diesel isn’t difficult but there’s almost always an incomplete burn of diesels especially at lower pressures and temperatures and this is why aging vehicles benefit so substantially from our ECU remapping as we account for the more inefficient injectors and spray patterns, boosting fuel pressures aiding in a massive improvement in an engines volumetric efficiency and complete burn of diesel on each engine cycle and this is how we improve power so substantially but still achieve better fuel consumption!!
It’s knowledge like this we also openly share to cut the stigma that has been associated with remapping vehicles and its normally because people all assume plug & play chips fall into the same category!!
As much as the chips may improve power levels, they negate a lot of sensor readings and important adaptations, corrections and adjustments the factory ECU continuously does!!
This is why ECU remapping reigns Supreme!!
