Tuning With No Load

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 before continuing.

Using the throttle only, increase the engine speed to the value of the first RPM row above idle. This is typically 1000 RPM. If the engine is at exactly 1000 RPM then only that range needs to be adjusted.
Adjust for a stoichimetric mixture, or the closest to stoichiometric as possible with the engine running smoothly and without misfire. Repeat for each RPM row, 1500, 2000, 2500, 3000 RPM etc.
The engine should now start and free rev cleanly with slow throttle applications.

While free revving at higher engine speeds, check the engine speed on the computer. If it becomes erratic, or fails to follow the actual engine speed correctly, check the Trigger Edge
