The ECU Job
The ECU Job contract has three missions: Train Inventory, Schedule, and The ECU Job.
Train Inventory (Planning Work)
The train inventory planning work is a pretty straightforward job. First, you need to make your way to Elysian Island as instructed. When you arrive at the location, you will need to disguise yourself as a dock worker by collecting the outfit from the van parked nearby.

The van is never in the same spot. It will always be random but within the vicinity of the boat. You don't have to worry about finding the van, as it will be shown on your mini-map, indicated by a small stick figure icon.
This disguise will allow you to blend in with the other dock workers. The Merryweather guards will not notice you unless you stay in their cones of vision for too long or bump into them. You will also be detected if they see you with an equipped weapon.
After getting the uniform, make your way to the back of the boat. Directly go towards the rear section of the boat and climb up using the stairs on the side.
When you reach the rear top of the boat, you need to start looking for the container manifest. There are multiple spawn locations where the manifest can spawn, and they are as follows:
Wooden Crate #1
This crate is on the left side of the middle partition at the rear end of the boat. The manifest will spawn on top of the wooden container.
Wooden Crate #2
The second wooden container is on the other side of the middle partition, directly opposite the first wooden crate. The manifest will be on top of the second wooden crate.
The third location is the dark green box on the second level. Climb up the stairs in front of the second wooden crate, and climb the ladders right after.
You will find a stack of green crates. The manifest will be on top of the stack.
Once you've found the manifest, take a picture of it and send it to Sessanta.
Next, you will be instructed to go to the front of the boat to steal an industrial cutting saw.
Go to the very front end of the boat and climb the ladders up to the top.
The cutting saw is in a bright blue duffel bag and can spawn on any one of the boxes (crates, wooden boxes, water tankers, etc.) located at the front end of the boat. We found ours on a wooden crate.
After grabbing the duffel bag, leave the boat and deliver the cutting saw to your Auto Shop to complete this mission.
Schedule (Planning Work)
This planning work is a simple mission. You need to go to a location, locate a train, and scope out the area by taking pictures.
Make your way to the location and take a picture of the train and send it to Sessanta.
Wait for her to contact you again and then take a picture of one of the brake cylinders and send it to Sessanta.
Then you need to find the train schedule which is in a control tower. The tower will be heavily guarded. It is best just to clear out the guards instead of sneaking your way in. It is much faster.
Once you've collected the schedule, deliver it back to the Auto Shop to complete this mission.
The ECU Job (Final Job)
When you start this job, the first thing you must do is select the 'Sharpshooter' as your weapon loadout. This is important as we need both the Sticky Bombs and the Heavy Sniper Mk II.
Also, make sure you are fully stocked up on super heavy armor and snacks, as this mission will be full of combat.
Once again, if you can afford a Jester RR, we highly recommend getting it and upgrading its tires to bulletproof and louvers for the back window, which gives extra protection against incoming shots.
Make your way to the interception point and wait for the train to come.
When the train arrives, ready your sticky bombs and throw them at the brake cylinders to destroy them.
You will get a notification that the brake cylinder has been destroyed.
After destroying all four of the brake cylinders, the train will come to a stop. Drive slightly ahead of the train to avoid the Merryweather soldiers' line of fire and take out your Heavy Sniper Mk II.
Use your vehicle as a cover and shoot the chopper five times to destroy it for good.
Get back into your vehicle and drive till the end of the train, killing all the Merryweather soldiers as you drive by.
Merryweather soldiers will keep on spawning, so you need to be quick about it and take them out. Whenever you see a chopper spawning, you need to prioritize the chopper over the foot soldiers as the chopper drains your health.
Once you've cleared the soldiers, you will get some breathing room. Check your messages to see the container codes you'll need to find the ECUs.
Those codes are sent by Sessanta, and you need to match with the codes on the side of the containers.
We got S8B5 and S91F. These codes are written on the side of the containers. Once you've found the correct container, interact with it to open them up using the industrial cutting saw.
If you've opened the correct container, you will find the ECU inside. Collect it and look for the second container.
As you collect the ECUs, more choppers and Merryweather soldiers will spawn. So take cover inside the train and first take out the chopper.
After the chopper, you can take out the rest of the soldiers. These choppers won't be armored like the first chopper that spawned in the beginning. You can easily shoot the pilot and they will go down.
After getting both ECUs, get back into your vehicle and deliver them to KDJ, a.k.a Moodymann. Just keep driving to your destination and you should be fine. This is where the louvers help protect you from the incoming shots from behind.
The mission is completed after delivering the ECUs to KDJ.
