each wire in the harness is marked every 70 mm (~3”) with its function in
clear text. This makes it possible to cut the wire to desired length and still
read its function.
1.1.3 NIRA rk
NIRA rk is the calibration software that allows you to setup and configure a
large number of parameters in NIRA i7x. It is designed to run on a PC using
the Windows operating system and communicates with NIRA i7x via a Kvase
CAN-dongle.
The many functions of NIRA rk are described in detail starting in chapter 4.

1.2 Glossary
Absolute pressure is measured starting at 0 kPa.
This is the pressure in vacuum. At sea-level the
absolute pressure is approximately 100 kPa, +/- 10
kPa depending on the weather (high or low
pressure.)
Methodology to compute the amount of fuel to
inject based only on rpm and throttle angle.
Sometimes referred to as “throttle mapped.”
This mapping approach can be difficult to use and
requires a high resolution throttle position sensor
potentiometer.
On engines with aggressive camshaft profiles, the
pressure in the intake manifold fluctuates
significantly. In such cases it’s not possible to get a
