The Element Hydra EMS has a number of closed loop fueling options:

Closed loop "14.7:1 AFR" utilizing the OEM rear 02 sensor. This is definable with a start and end rpm plus a load range within vacuum.

Closed loop "14.7:1 AFR" utilizing the Hydra WB 02 sensor. This is definable with a start and end rpm plus a load range within vacuum.

Closed loop "Wideband Target Table" utilizing the Hydra WB 02 sensor. This is definable with a start and end rpm plus all load ranges including boost. The target AFR is defined by a 32x32 ""Wideband Target Table" so you can decide what AFR you want to run for a given load and rpm.

Closed loop/AutoTune "Wideband Target Table" utilizing the Hydra WB 02 sensor. This is definable with a start and end rpm plus all load ranges including boost. The target AFR is defined by a 32x32 ""Wideband Target Table" so you can decide what AFR you want to run for a given load and rpm. The difference here is that this alters the fuel map permanently by tuning the fuel table until the AFR matches those set in the "Wideband Target Table."

Whatever is outside of either your rpm range or load range is then open loop fuel control.

Thanks,
