The 1 Series were born with common-rails and have been tuned by us thousands of times, both in Italy (where we manufacture) and abroad. The most tuned engines with our CHIPBOX ECUs in the early years were the 16-valve 2-liter common-rails, especially those with 163hp. In the years following the early versions, other power ratings of the 2-liter turbodiesels were introduced right up to the very frequently tuned bi-turbodiesel version.

As a result of the architecture and operation of electric engines, they do not need to have a minimum RPM. Furthermore, they can deliver maximum torque even at zero RPM, practically from a standstill! Sounds strange, doesn't it? Yet it is, and to understand it, we need to know how an electric motor works for automotive purposes, which in many ways is not very different from an electric RC model engine.

One of the main factors that make it possible for many people to reduce their fuel consumption is that the chip tuners increase torque in almost all cases, even at low engine speeds. On average, this allows greater use of the high gears of the transmission, especially in a manual car, where the driver makes use of the gearbox with this intent.

Viscous coupling is a mechanical component that is used in some passenger car transmissions. Normally there are two uses: one in which it is employed as an additional organ for self-locking differentials (on both 2WD and 4WD transmissions) and another when it acts as an auxiliary element in non-permanent all-wheel drives.

In recent months we have received several reports concerning a new problem related to remapping the ECU of several BMW models. The problem relates to remapping the most recent models, which, while remapping provides excellent increases in power and engine torque (and thus performance), it also generates two problems. Let's have a look at what these problems are.
