10 cent tuning for common-rail engines

a possibility :::::::

spoofing the signal from the rail-pressure sensor by means of
resistance in series with the signal lead from the sensor, the whole thing over a
kick-down switch on the accelerator pedal (when full throttle is open) and an additional switch in parallel
to disable the entire thing
Additionally, I suggest adding a second resistor with three diodes in series to the other resistor, so that the distortion in the area of the maximum pressure is reduced.

this method is the same as the one used for the suction pressure (charge pressure) sensor.

- this whole thing results in approximately 15-25% more power and torque
- the rate of distortion is increasing with increasing rail pressure
- when idling (when the kickdown switch is open (full throttle)) with a sensor voltage of 1-1.3V
ca. 3-6% more pressure
- in the partial load range (when the switch is open), approximately 6-13% more pressure
- at full load, up to 1000 bar, approximately 13-18% higher pressure
- in the range of 1300 bar (maximum pressure), approximately 13-16%

ATTENTION!!! Only use with diagnostic device.
- The control valve's operating ratio shall never exceed 80%.
