Minimum temp settings

[funcars]

I had Buschur Racing install my AEM EMS and tune it in my 91 Talon. Which runs really good and strong, BR all the way. Well in the winter under 36 degrees it would not prime the fuel pump. So I changed the temp settings under options then configure. I set them to -24 degrees. It is still not priming. What other temp settings are there? I already changed the under hood sensor just to make sure it was in good shape. Im sure there are more but havent found them. Any help would be great.

I'm surprised that was missed, very sorry. There is a fuel pump default that was set to 32 degrees back in the early 2000's but none of those maps should be left around. If you set the min temp for the fuel pump to -24 and it still doesn't prime something else should be wrong. Sure the fuse isn't blown?

Thanks. I'm sure thats the one I already changed, but will double check in a few mins. Fuel pump fuse is good just drove it two days ago when it was in the low 40's. Now we got this mid 20's in southern Ohio and no prime. On aem forums one individual said there are like 3-4 different ones. But he listed them as L8-L6-L11 (not sure those are the exact ones). I found the one under configure outputs and a page under fuel that had a min and max temp.. I'm not sure what the correlation is between the codes he listed and where they are on the screen. The fuel pump default setting under options or fuel? The one I saw was under options but was listed as coolant temp.Sorry I'm still learning.

I went through the whole list of options. Any that where set at 32f (default), I set them to -24. And it finally started up in this 17deg. weather. I will probably change them back one by one until it does not start. Are there any specific ones that should not be set that low? Any that where pre-set I did not touch, but there where several that I believe dont affect me. Like the coil temps. Any help is great help.

I would leave them ALL set low. We don't all live in California where they figured out 32 degrees was a safe default number! haha
