In order to do a proper EGR delete You have to do following:<\/strong>
\n– EGR delete ECM tuning
\n– block off EGR gas flow
\n– unplug EGR valve connector
\n– unplug EGR sensor connectors<\/p>\n

ECM tuning:<\/strong>
\n– Our ECM tuning will allow you to block off EGR valve, and unplug all EGR sensors.
\nKeep in mind that along with EGR delete, we must delete all the filters on exhaust (DPF DOC SCR), and DEF if the vehicle is equipped with it.
\n– All our Cummins EGR delete tunes come with a fleet safe power upgrade.
\nThis upgrade will provide You the best fuel economy.
\n– List of all our delete tunes for Cummins engines.<\/p>\n

Work that needs to be done:<\/strong>
\n– The basic principle for blocking off EGR is the same on all engines.
\nEGR has to be blocked with steel plates on both cold & hot side.
\n1st block off plate goes on position where EGR manifold meets exhaust manifold.
\n2nd block off plate goes on position where EGR manifold meets intake manifold.<\/p>\n

– The reason we recommend blocking off EGR on both sides, is because that way engine will run the best.
\nOnce You block off intake(cold) side, Your intake manifold air volume & geometry will not be messed by EGR tubing.
\nThere will be no chance of sucking air from EGR manifold, and that way causing an air leak.
\nSame thing is for exhaust(hot) side, Your exhaust manifold geometry will be again according to factory spec.<\/p>\n

– Here is an example of the EGR’s hot side plate position.
\nThe photo is taken on CM2250\/CM2350\/CM2350A X15 ISX, but all other Cummins engines(CM871, CM2150D, ISL, ISC, ISB, ISM) are similar<\/p>\n

– Next thing to do is unplugging EGR valve’s electrical connector.
\nAgain, this photo below is from CM2250\/CM2350, but all other engines are similar.<\/p>\n

\"\"<\/a><\/p>\n

– Now we need to unplug EGR sensors.
\nThere are two types of sensors we need to unplug:
\n– EGR differential pressure
\n– EGR temperature sensor
\nBelow are the photos of EGR sensors locations on CM2250\/CM2350\/CM2350A X15 ISX.<\/p>\n
