closed loop question

Post by panoramix3519 »

When i work in closed loop and the ecu is trimming the maps for example 4%, when i go full throtlle so i am in WOT so i am in open loop, the trimming from closed loop the 4% is still triming from the maps or the trimming is working only when i am in closed loop and when i go to wot is the maps working without triming?

Yes you have a value in closed loop parameters it is the maximum MAP for closed loop, above this MAP it is open loop

It will use the fuel trim in open loop for safety.
