engine operation. This is used for limp home in applications where pressure is the
primary engine load input.
Calibration range is in KPa(Gauge).
Advanced Setup
Setup the engine TDCs for ignition and fuel odd fire/dual injector engines.
THIS IS AN ADVANCED FUNCTION.
Base angles (IGN)
Base angles (Ignition).
First make sure that you coils, number of cylinders, ignition edges and dwell
control mode is set as changing any of these later on, will remove your custom
TDC setup.
Also make sure that "Engine setup","TDC spacing" is set to a known setup.
Now edit the angles at each TDCs to suit your engine.

Base Fuel Delivery
Basic fuel delivery calibration table providing fine (0.1%) adjustment of fuel. This table,
the engine "load", barometric pressure and corrections dependent upon intake and
coolant temperature, acceleration and deceleration and external trims determine the
actual rate of fuel delivery for all engine operating conditions. The table data values being
a representation of the engines "Volumetric efficiency" allows considerable simplification
of the calibration procedure. Up to 32 engine speed and 16 engine load dependent
calibration sites may be chosen at random calibration intervals giving up to 512
adjustment points.
WARNING
BASE ANGLES (IGN) NEEDS TO BE IN INCREASING ANGLES ONLY.
ROLL OVER FROM 720 TO 0 IS OKAY, AS THE ANGLES ARE STILL
COUNTING UP.
WARNING
BASE ANGLES (FUEL) DOES NOT HAVE TO BE IN INCREASING ANGLES
LIKE "BASE ANGLES (IGN)".
