Autotune™
Software Setup
Step 1.
Select menu M1, Engine setup.
Set “A/F ratio sensor” = Linear I/P A/F meter.
Step 2.
Select menu M1, ECU A/F control.
Set “Open loop table” = Enabled.
Step 3.
Select menu M2, Target A/F ratio table (open loop table)
Setup this table with the “Target” air fuel ratios you wish the Autotune™ software to tune
the engine.
Below is an example table for a turbocharged engine. There are many engine variables
that effect the required air fuel ratio, plus fuel octane and the application the engine will
be used. A engine used for drag racing can use leaner mixtures than an endurance
engine.
