What engine parameters would I have to change in order to decrease the Air Fuel Ratio atfull throttle?

[bananatofufrogboi]

Our class is using the engine simulator to simulate maximum horsepower and throttle using the dynamometer feature after changing engine parameters in the engine code. But after tweaking several lines of code, the full throttle Air-Fuel Ratio always ends up at 13.3.

What engine parameter should I change to decrease it?

Pretty sure the sim will always target AFR of 13.3 for power, I recommend taking a look at the following repo which is more updated.

Possibly under intake you can do the following

intake intake1( plenum_volume: plenumVolume * units.cc, plenum_cross_section_area: plenumCrossSec * units.cm2, intake_flow_rate: k_carb(intakeFlowRate), runner_flow_rate: k_carb(runnerFlowRate), runner_length: plenumRunnerLength * units.mm, idle_flow_rate: k_carb(0.01), velocity_decay: 1.0, molecular_afr: airfuel_ratio, idle_throttle_plate_position: idle_throttle_position )

Thanks for the input. Took a while, but I found where the "molecular_afr" line of code was. Turns out it was in engine-sim-v.0.1.14a\es\objects.mr
