Using the cross hairs Cross hairs are provided on the tuning grids to help you bring the engine load/RPM up to match the load cell being tuned. When the cross hairs are centred in the load cell this means that this is the best time to adjust the cell value.
The engine must be up to operating temperature before tuning.
The engine must be held as close as possible to load / Rpm point being
adjusted. c) Temporarily disable the acceleration enrichment while tunning.
Clear Flood Mode
Clear flood mode is used when the engine is flooded. A throttle position sensor must be fitted. When the throttle is pressed passed 90% while cranking, the Ecu will not fire injectors. This allows the engine to clear any excess fuel in the manifold.
Tuning grid command keys
These commands are also available on a pop-up menu when you right-click on the tuning grid.
Page-Up and Page-Down Keys Press the page-up key to increase the value of a cell by 1 and Page-down to decrease the value by 1.
You can also select a range of cells and increase or decease them by pressing the Page-up and Page-down keys. Use Shift and any combination of arrow buttons to highlight / Select a range of grid cells that you want to adjust and then press the Page-up or Page-down key to increase or decrease each cell by 1.
Auto Trace (Space Bar) You can automatically position the cursor onto the load/rpm point of an engine while the engine is running by pressing the space bar. If you keep the space bar pressed then the system will trace the engine as it moves through each load point. Each load point will be highlighted with a green boarder indicating the load path of the engine.
You can clear the path by pressing the "Clear Trace" button or "alt + c"
NOTE: When barometric compensation is active the load point that the ECU is using may not match with the Manifold Pressure being displayed on the live gauges. This is because the ECU now determines the load point based on volumetric efficiently.
Insert RPM Column (Ctrl +Right Arrow or Shft+Alt+C) Press Ctrl then Right Arrow to insert a new RPM column in between the current cursor position and the column to the left. This will push all RPM columns from the cursor (including the cursor) to the right and then insert a new one.
