CHAPTER 5 STARTING THE ENGINE
There are a few things that need to be done before the engine should be started. M ake 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 that the ECU Set-up: M ain Set-up and Fuel Set-up are correct.
5.1 Calibrating the Throttle Position Sensor
The throttle position sensor (TPS) must be calibrated so that the ECU closed throttle (0%) and
wide open throttle (100%). 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 F10 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
trigger is operating correctly then enable the injector output again on the Fuel Set-up page. (If
the rpm reads “0” or is erratic; Refer Appendix D Trigger Interface, 92).
5.3 Determining Engine Fuel Needs
You should now be ready to start the engine. At this stage, you should not be using the Zero
Throttle M ap. Check that it is disabled in the Fuel Set-up.
Go to the Fuel maps and display the 0 rpm range. During cranking, the pointer will appear
across this page, until the engine speed picks up and lifts into the 500 and 1000 rpm ranges.
Press the
   
key to jump to the current load point immediately.
If you are using manifold pressure as the load sensor, the engine will be close to atmospheric
pressure during cranking. If you are using throttle position, then the F10 will be using bar 1
while cranking and idling. Once the engine is tuned, you should not need to apply any throttle
to get the engine to fire. When cranking the engine watch for the indicator arrow over the
bars. This will tell you what bar the F10 is using to calculate the fuel. The bars around the
position that the arrow indicates are the Bars that will need to be adjusted to get the engine to
run.
Note: The bar that is indicated by the arrow is the bar that the ECU is
referencing for its fuel needs whilst the bar that is highlighted is the bar that
you are adjusting.
If the engine is not firing at all, check that there is spark. Also check that the spark plugs are
clean and are not wet. It is unwise to crank on the starter motor for extended periods. The
engine should fire and run within the first few seconds of cranking.
