94170715 - Tephra V7 Min Temp for Closed loop

Is there any way to add an address to change this setting for this ROM? My car is very picky at cold idle, usually running lean, with my factory 94170008 I had the temp set at 120* or so and it helped with a smooth warm up and AFR. I don't have this setting in 0715, or at the very least I don't see it, and hours of searching has turned up nothing. Any possible solutions?

No one has a lead on this? Maybe if anyone has the stock 94170015 ROM they can see if they have that setting? I had it in my 94170008 but who knows if the addresses are the same

I fixed this code before, it had something to do with the rear o2 being disabled improperly.

make sure Tephras rear o2 simulator is set up to disable rear o2 heater.
turn on rear o2 in periphery0,
set bit. 1 to 1 in periphery1
set bit. 1 to 0 in periphery4

Thank you Merlin! Are you sure it's ab and not aa? I get erroneous characters with ab but 45F with aa

It is a one byte parameter, so 15AB.

You can us a 2-byte temp scaling (as I generally do) if you wish and then it would be 15AA.

Mine must be 2 byte because the 15AA was the winner. Took me a while to figure out how to put the setting where I want by editing the XML file, but this was my end result, with an OL-CL switch at 120*F

table name="Min Coolant Temp for Closed Loop" category="Warmup Settings" address="15aa" type="1D" level="4" scaling="Temp"

Of course with the < / > at the start end of the code, but if you put that in here it erases the code...

Worked perfectly, need to adjust my cold idle fuel settings a bit but it idled much better warming up. Thank you very much, and hopefully anyone else looking for this answer finds it here
