What does "EFT1" monitor?

This might need to be in the performance section but I'll try here first. What is my Spartan tuner monitoring "EFT1"? It's been cold in Ohio so that's been running about 80-90. Then today I fueled up and went home and shut the truck down for about an hour. When I fired it up the Spartan was warning me about something and the EFT1 reading was in red and reading 140. I restarted the dasdaq and it had gone down to 120 then as I drove went on down to 103. The temp here today is only 76. Do I just need to adjust the danger zone on this? What is it? What's the normal range?

Eft1 is Fuel rail temp. Check your fuel coolant reservoir and see I it's low.

Ya it's a little aluminum tank with a sight glass on the side and a small radiator cap on the top. Like 04hdfatboy said drivers side, mounted high and near the firewall.

Soooo has anyone else had their Spartan DashDaq (that is still pre-set from Spartan) have this issue? I'm not throwing a code or anything. It almost appears as if the "limit" is 140 as both times it's happened it's ready 140 then after a idling/driving for about a 30-40 seconds it cools back down to below 140 and stops beeping. Does anyone know what Ford says is the Max fuel rail temp?

use to happen to me when I had my spartan. It's fine you can live with the warning or bump it to high number or turn off the audio alert. the reason it trips is the coolant is not moving after you stop the motor and heats up.
