Here is what the stock map looks like :

hi Brettus, Did this work for you? I have a JDM 2005 model and it seems to stay in closed loop until the 6k rpm exit even if i lowered the values in the "unkn" map.

Hi , yes it does work but only at low rpm I believe . If you want to exit closed loop at higher rpms just adjust the 'closed loop exit rpm' parameter.

My Versatuner Load Limit UNK table looks exactly like that table above, and my 2007 also has inconsistent exit from CL into OL between 2,000-5,000 rpms. i wonder if i should set the values to ~0.75 or 0.80 between 1,000 and 5,490...?

Also, has anyone ever played with the acceleration enrichment tables, that seem to add fuel at heavier loads in the 1,500-3,000 rpm range? Or should i just tune with the air fuel tables?

Follow-up: Load limit unknown was indeed screwing my attempts to tune in the 2,000-5,000 rpm range.

i changed my load limit unknown values to around 0.65 - 0.75 as rpms increase between 2,000 and 5,490, and now it is easy to enter open loop and rely upon the air fuel ratio tables for tuning.
