Enrich Power AFR Enable Min. Temp.

I noticed both in my stock bin (AXXF) and in the S_AUJP this is set to 116.75 Deg C which is 242.15 Deg F. Now judging by this temp it seems to be set so high that you don't ever want this variable to kick in, is that right or do you want it to kick in?

I ask because I have a 180* thermostat and between that and my fan settings my car normally runs at full temp 182* sometimes reaching 189*. In extremes it will go up to 195*. I already reworked about every variable there is in the bin for this new lower full temp I run now except for this one.

So bascially considering my new lower running temp what should I set this "Enrich Power AFR Enable Min. Temp." variable to?

Thanks

EDIT: Also what about the "Stay Alive Memory Enable/Disable Temp." variable, where should that be set?

I could be wrong, but I think there is a PE temp enable for HOT PE. This allows a lower PE enable %TPS for and Overheating engine to help cool it with fuel, I suppose, and reduce knock tendancy and shuts off integrator and learning. It could be a mislabled variable. If you have a wideband, can you see it going rich at WOT? I'd check around and look through any hacks you can find, and see if they have it labeled differently.

This has an $8D hack. Just look for your variable location in here (right click, edit ECU item, and look at the start address - 602 for this one), and it says use table L8608 if coolant temp = this or greater, and then look at the description for L8608, and it says it's for hot coolant. So, I think my assumption is correct, and that temp sets the PE enable TPS to the Hot PE enable TPS.

I've found lots of cool stuff digging through 32B code and finding the correct location in the $6E code using this method.

Thank you. I figured it was along those lines but wasn't sure exactly what.

I've set mine to 115.25 Deg C which is about 239 F.
