Toyota 22R-E air/fuel ratio ECU coolant signal hack / bypass tuning module for hesitation lag at WOT

Описание к видео Toyota 22R-E air/fuel ratio ECU coolant signal hack / bypass tuning module for hesitation lag at WOT

This video covers a little micro switch / ECU mod I did on my Toyota 22R-E motor which helps prevent engine hesitation / acceleration lag (due to a sudden lean condition) when running the factory ECU on a modified / performance motor and going WOT from cruising. In the video I discuss closed loop as well as open loop operation and how this modification of the THW coolant signal can help fine tune air/fuel ratios under heavy loads (outside of that which the factory ECU can fully handle).
