excesive time to enter closed loop... origonally the 9653 rom i was using the min temp for closed loop was set at 70c and had no problems. i switched to 9055 for a while then went back to 9653 and started getting this CEL. eventually i droped the min temp to 7c and it went away.

 

I am not even seeing this table in my 9653 Rom.

 

Have not had this problem with the tephra V7 t5 version of this firmware, in fact we watched the trims update on my car, right up until I ran over my intercooler piping (hey teph, any chance you can throw in a SD patch for limp mode? :-D )

 

I have no problem logging trims and my latencies are all nailed down but yet I still throw a P0125 once in a while.

 

try putting this in your 9653 xml

<table name="Min Coolant Temp for Closed Loop" address="15aa"/>

and put this in your evo7base xml

<table name="Min Coolant Temp for Closed Loop" category="Fuel" type="1D" level="1" scaling="Temp"/>

or drop this combined line in your 9653 xml

<table name="Min Coolant Temp for Closed Loop" address="15aa" category="Fuel" type="1D" level="1" scaling="Temp"/>

 

Thanks a lot man!!!

 

Sorry for bumping an old thread, but just wanted to see if changing this temp did infact cure the P0125 code for any of you.

I just added the line to my 9653 xml and saw it was set at 32F. Being that its been pretty cold here in Va lately im hoping by dropping that temp down to say 10F (probably a little extreme) will make this annoyance of a CEL go away.

 

Just thought id post up that dropping the min coolant temp to 10* did nothing for me. Still got P0125.
