GOOD RIDDANCE! GM was early EGR (LLY) and the 6.7 nightmare was 3 years ahead being 2010 compliant in 2007. Some of these morons who did this early emissions beta testing on us do not work at the auto companies anymore. How Biodiesel ever got approved as an alternative fuel with it's increased NOx emissions by the EPA is a mystery.įurther information is both GM and Chrysler shot themselves in the foot by trying to introduce emissions earlier than the usual gun held to their heads by law. You can't see the increased NOx.Īnd NOx is worse with running B99. Blocking the EGR visibly cleaned this up. Just watching a LMM towing with no more than the DPF removed was interesting for the visible smoke. Lml duramax egr delete install free#The free flowing exhaust has already reduced the EGR flow. So your timing may become advanced by eliminating EGR. This is why tighter standards have to use Urea for NOx control as PM gets out of control.ĮGR use has an affect of slowing the burn. It is the ultimate clusterF# where towing heavy doesn't burn the DPF clean as the PM entering it is so high from so much EGR use. PM is unburned wasted fuel that plugs your DPF that then takes even more fuel to burn out clean. The EPA has a hard on to reduce NOx and particulate matter, PM, that shows up as reduced MPG and higher prices at the grocery/other stores from delivered goods. It requires serious plumbing changes to the exhaust and intake and in my opinion is only advisable for the hard core racer.ĮGR reduces NOx. Essentially an EGR delete removes the EGR valve/motor assembly along with the EGR cooler etc. It also requires ECM programming to deal with the DTC’s associated with removal of the EGR motor. EGR delete by my definition is complete removal of system components which is a highly invasive and unnecessary procedure. Then some unsuspecting “diesel newbie” hears this and goes out and orders an EGR delete kit not knowing what he/she is in for. Lml duramax egr delete install mod#People tend use the term EGR delete universally for any mod relating to the EGR. This one has been growing in popularity as of late and is a key source of frustration on my part. Simply put, the system and diagnostics are disabled. This is accomplished via ECM programming. It will never give you grief and there is no invasive wiring, blocking, or component removal. With this mod even if the EGR motor or position sensor fails there are no resulting issues or codes set. The operation of the EGR is simply ceased within the ECM programming. This is simplest and most permanently effective way of dealing with EGR related issues. This often makes this mod a pay me now or pay me later type of proposition. Lml duramax egr delete install upgrade#We have seen plenty of the EGR motors fail requiring replacement or upgrade to programming to fix. The EGR blockers have proven over time to be quite effective, but Installation involves cutting and soldering of your engine’s wiring harness along with insertion of the blocker plate between the EGR cooler and the vehicle exhaust system. The Finger Stick (named after its creator Jon aka “Fingers”) and a stainless steel blocker plate to prevent flow of exhaust through the EGR cooler. The Blocker package consists of 2 components. That is not to say this is a bad option, it’s just the old way and requires a functioning EGR motor and position sensor in order to function properly. We offer the EGR Blocker packages as a cheap “band aid” approach to take care of these issues. If you are the type who likes to skip forward to the conclusion I’ll make my suggestion right here and now: EGR disable via Kennedy Programming This Tech Tip has been written in an attempt to educate and minimize time spent on the phone discussing something that shouldn’t be so complicated. Warning: Emissions tampering is unlawful on any motor vehicle used for on road purposes in the US. If somebody has a dumbed down version of how the EGR actually works that might help too.ĭuramax EGR Blocker vs. Good read for anybody just getting into this stuff, from Kennedy.
