AEM EMS Blowing Fuse
I've hooked up my AEM EMS, and I've had it hooked up permanently for a couple days now. Today, as it is idling, the 10A fuse I highlighted in the picture blows after a few minutes of idling and the car shuts off. This has occurred 3 times today, and it was not happening earlier.
What is this fuse powering exactly? I'd like to trace what is pulling 10+ Amps.

I am running the spoolin up cop, yes. I had never heard this before; AEM recommends this?
On a side note, I'd like to confirm how I have my AEM Uego wideband (35-3401) wired. I have the white 0-5V wire going to pin 76 on the EMS.
Do I need to attach the ground for the Uego to the ECU? The EMS diagram shows black going to chassis ground, and a non-existent brown wire going to pin 92 for ground. Does the blue serial wire go to pin 92 on the ECU, or is a ground to the ECU from the UEGO not necessary?

I have a difficult time understanding why stock dwell settings could blow a fuse at idle with the spoolinup.
Thanks

My dwell settings are set to how AEM's Evo base map has them. Do you know what approximate settings guys use with the Spoolinup cop? My tuner can adjust them later once I hit the dyno.

Maybe somebody that has the spoolinup kit and an AEM can give you their settings. The only other thing I could think of is a wiring issue with the spoolinup kit causing a short or an issue with the coils. Does it blow the fuse after approximately the same amount of time idling each time?

I went through 3 10-amp fuses today. There was no specific timing as to when the fuse would go, but it was always during idle.
I had the Evo VIII coils selected in the coil dwell wizard. Since it is a Toyota coil, I may try one of the Toyota coil configurations.
I moved to a 15-amp fuse, and I haven't had the issue again today.
Thanks for the info.
