Tuning Fuel
Quicktune Feature
The Haltech Quicktune feature is a feature that helps to automate the tuning process by performing the comparison between target AFR and measured AFR, and then performing the appropriate injection time adjustment. The Haltech Quicktune feature can be ...
Applying Load to the Engine
WARNING To avoid engine damage, an engine should always be tuned rich then slowly leaned out until the desired AFR is reached. Always ensure that an engine is in good condition before performing any tuning. Watch coolant temperatures closely during ...
Tuning With No Load
You should also have the engine running at operating temperature before doing any tuning of the base maps. Go to the Engine Data Page at this point and check all the sensor inputs are reading correctly, and that the temperatures have stabilised ...
Tuning for Idle (fuel)
The idle mixture is very sensitive to changes in injection time. Idle injection times are usually around 1.5 to 2.5 ms. If the injection time at idle is much lower than this, it may become difficult to set accurate idle and cruise air/fuel ratios. ...
Tuning Base Tables
Tuning Method Injection Time The fuel table contain the base injection time for the given load and RPM at which the engine is operating. The base fuel map has the greatest influence on the air/fuel (A/F) mixtures. With injection time tuning, you ...
