Ecu fuse keeps blowing

Hey guys anyone have any ideas what could be causing my engine cont fuse (ecu fuse) to keep blowing. It happens randomly and once it blows it keeps blowing until I leave the car off for a few hours and change the fuse.

I have air suspension, a manual swap and a lot of our mods. But nothing other then the manual swap shouldn’t really affect anything for the ecu though

Any codes?

Here is a schematic of everything that is connected to the ENG CONT (#50) fuse:

I would start by checking for water in/near/around the ECU area... just in case.

Then, I would check your wiring harnesses for any signs of damage. Make sure everything is clean and tight.

Didn't you replace a coil pack? They are on this circuit... just saying.
