CHAPTER 5 STARTING THE ENGINE
There are a few things that need to be done before the engine should be started. Make sure
that the ECU is powered (ignition on) and the Haltech Software is ONLINE. Go to the Engine
Data Page to check that the ECU is communicating properly, and that the sensors are reading
correctly. Check again that the Identification, the Fuel Set-up and the Ignition Set-up are all
set correctly. In particular, check the No. Cylinders, Ign Div/By, Load Sensor and Injection
Mode parameters. If any of these are incorrect, the engine may run, but proper tuning will be
impossible.
5.1 Calibrating the Throttle Position Sensor
The throttle sensor must be calibrated so that the ECU knows the start and stop positions of
the sensor. Set the idle throttle opening using the idle adjust screw. If the required opening for
idle is not known, make an estimate but keep in mind that this may be the reason for poor idle
later on, and further adjustment may be needed. Choose the "calibrate throttle" option from
the options menu and follow the instructions on the screen.
5.2 Checking the trigger
It is a good idea to check that the E6H/E6M is receiving a reliable trigger signal. Disable the
injector outputs found in the Fuel Set-up page to cut all fuel delivery to the injectors. This will
prevent the engine from starting. The engine should then be cranked over on the starter and
the rpm displayed on the engine data page should read about 100 to 300 rpm. If the engine
speed is zero or is erratic then refer to the section in Chapter 1 [1.3.14] regarding trigger set-
up. If the trigger is operating correctly then enable the injector output again on the Fuel Set-up
page.
5.3 Checking the Base Timing
The E6H/E6M uses a timing reference taken from either the cam angle sensor or flywheel
sensor. This gives the E6H/E6M the reference on which to position all ignition timing. If the
timing is wrong then the E6H/E6M cannot function correctly. To ensure that this base timing
is set correctly the E6H/E6M has a LOCK TIMING setting.
When the Lock Timing is set, the ignition timing is forced to the Lock Timing Angle (this is a
preset value between -5° to +25° Before Top Dead Centre (BTDC)). This is regardless of
whatever ignition timing Maps are currently in the E6H/E6M.
To enable this flag, press
ƒσ
from the Sub-Menu to select the Ignition Set-up. Using the
arrow keys move to the Timing Lock option. If it reads Lock Timing On, the flag is enabled.
If it reads Lock Timing Off, then the flag is disabled. The flag is toggled by pressing
♥
. If
the Timing Lock is on, the ECU will lock the timing to where it believes the Lock Timing
Angle advance to be.
