Default what are the conditions for closed loop?

ok well closed loop enable temp is set at 34 for now but i will be changing it soon. the transition from olfa to closed loop at 14.63 happens at about 45*c, well if its enabled at 45*c what delays it or makes it delayed, once the o2s oscillate it enters closed loop. but why wont it enter at 34*c?

hahahahaha talk in fahrenheit please......


anyways i think its something like 90+* for it to go into closed loop. If you change the closed loop enable temp you can make it enter cloed loop faster or stay in open loop longer

yeah sorry thats just what my table was in and i didnt want to close out to change it lol

well thats the only table to be changed for closed loop enable? why is it on cold start my car will reach the set mark ~90*F and still be in open loop? it wont enter closed loop until about 115*F

I am pretty sure there are other criteria but 92* fahrenheit seems to be one of the criteria to enable it

What are you trying to do

trying to delay closed loop to a warmer temp possibly, depending how things go tomorrow with other parts of the tune, o2s jsut arent hot enough to be working and giving feedback as soon as they are.
