！Before installation, confirm that：
This high-performance component does not comply with the laws and regulations for highway driving and cannot be used on any vehicle that has been registered or certified for use on highways. This means that the component may only be suitable for racing cars or other off-road vehicles. If it is installed on vehicles driving on the highway, legal issues will be borne by oneself.
Note: For your safety, we recommend disconnecting any negative battery terminals when working on any vehicle, installing cold air intakes requires removing the pipe from the turbine intakes, using paint and not allowing any dust, debris or tools to remain where they may enter the system.
This is the installation process for the ER-0074: 2010-Present Stage 2 ISX 15 CM2250 CM2350 EGR Delete Kit,provided for your reference during installation.
ECM tuning is required before installation:
Close the EGR valve and unplug all EGR sensors through ECM adjustment.
Please remember that while deleting the EGR, we must remove all exhaust filters (DPF Doc scR) if the vehicle is equipped with DEF.
Step 1:
The basic principle for blocking off EGR is the same on all engines,EGR has to be blocked with steel plates on both cold and hotside.
1st block off plate goes on position where EGR manifold meets exhaust manifold.
2nd block off plate goes on position where EGR manifold meets intake manifold.
The reason we recommend blocking off EGR on both sides, is because that way engine will run the best.
Once You block off intake (cold) side, your intake manifold air volume and geometry will not be messed by EGR tubing.
There will be no chance of sucking air from EGR manifold, and that way causing an air leak.
Same thing is for exhaust(hot) side, your exhaust manifold geometry will be again according to factory spec.
Cummins EGR block off - Hot side/Cold side
Here is an example of the EGR's Hot side and Cold-side plate position.
The photo is taken on CM2250/CM2350/CM2350A X15 ISX, but all other cummins engines (CM871,CM2150D, ISL, ISc, SB, ISM) are similar.
Step 2:
Next thing to do is unplugging EGR valve's electrical connector.(photo below is from CM2250/CM2350, but all other engines are similar.)
Now we need to unplug EGR sensors.There are two types of sensors we need to unplug:
1nd EGR differential pressure
2nd EGR temperature senso
