Edge install. Any tips?

[woodynorman]

Pretty much my first post here...It's good to have such a knowledgeable bunch of people to get info from!

I just got my Edge Juice w/Attitude tuner for my 2014 6.7 2500 Ram. Hope to install it this weekend.

Any tips, tricks, or pitfalls to watch out for?

I'm not sure about the EGT sensor. Do I really need it? I was hoping the trucks computer would monitor EGT's, and the Edge would read it, but maybe I'm wrong?

Would appreciate any info...

Hi Woody, no personal experience yet, but you'll find lots of posts about the EGT sensor. General consensus seems to be that since you're pushing the engine beyond what Cummins designed, you should monitor as much data as possible to make sure you don't overdo it.

I would install the EGT sensor, the Edge products are known for running VERY hot on anything 03+.

So I got the Edge installed. Well everything but the EGT probe. It's just a pain to get to and drill the hole in the right place.

It appears as though I can get 3 different EGT readings without it. I have Post DOC EGT, Post DPF EGT and Post Turbo EGT.

My question is...can I use one or more of these temps as a reliable way of monitoring EGT's? If so, which reading would be best? And if so, what would be the equivalent values to the exhaust header EGT sensor? In other words....a 1300* exhaust EGT=how many degrees Post Turbo, etc...

Thanks!!

Post turbo would be the only one to watch. Before emissions started really taking an effect on diesels the general rule of thumb was 300°, since the start of tight housing turbos and variable vane turbos that number varies from 100-400°.

Those numbers seem low. Just cruising at 45-50 mph, its around 400* I think. I've only driven it a little bit though, and was playing around with the gauges so I'm not totally positive on that.

It also depends on how far post turbo the probe is, each inch does make a difference

 

[woodynorman]

So I did a little googling and it seems the general safe max temp, post turbo, is 800*. I will use that temp until I install the probe in the manifold, which appears to be the proper way to measure EGT's.

It seems that the post turbo temp is good to monitor shut down temp. Anyone have a good number for the proper shut down temp?

I'll bet you a nickel you exceed 800° during regen.

Post turbo should be under 350° for shutdown after towing. The rest of the time it's probably cool enough below 400°, and if you are in regen it won't ever get that low.

I'll bet you a nickel you exceed 800° during regen.

EGT1 is located post-turbo at the bottom of the exhaust down pipe just in front of the Diesel Oxidation Catalyst. On my 2014, this sensor doesn't show a noticeable increase in temperature during a regen cycle. However, EGT2 which is located just after the Diesel Oxidation Catalyst and just prior to the Diesel Particulate Filter shows a marked increase in temperature during regen. EGT2 usually reached 1000F or more. EGT3, which is located just after the Diesel Particulate Filter, also shows elevated temperatures similar to EGT2 during regen.

This observation (EGT1 not increasing in temperature during regen) leads me to conclude fuel is being injected in the cylinders post combustion, where it travels unburned down to, and reacts with, the Diesel Oxidation Catalyst. This reaction is creating the high exhaust temperature needed to burn the accumulated soot from of the Diesel Particulate Filter. Meanwhile, the exhaust manifold, turbo, and down pipe stay cool. Only the exhaust system from the Diesel Oxidation Catalyst onwards is super heated.

Best regards,

It appears as though I can get 3 different EGT readings without it.

There should be 5:

EGT1 - Diesel Oxidation Catalyst Inlet
EGT2 - Diesel Oxidation Catalyst Outlet
EGT3 - Diesel Particulate Filter Outlet
EGT4 - Selective Catalyst Reduction Mid Bed
EGT5 - Selective Catalyst Reduction Outlet

Best regards,

John L.

It appears the '13+ trucks may have revised the post event a little, I know on the 07.5-12 the regen was visible on pre-turbo pyro's, and post-turbo pyros.

 

[woodynorman]

When in regen, the post turbo EGTs are way high. Like 600-800, with very little load.

I'm pretty sure the post turbo EGTs are way higher than most think they are. I can easily hit 800 with hard acceleration. This is with just maybe 1000 pounds of cargo. That is stock setting on the Edge. On power level 2 or 3 it climbs over 800 easily.

I'm real curious to get the pre turbo probe in there so I can really see what's up

how is the edge juice working out for you? did you get your pyrometer installed? what kind of temps are you seeing? would you recommend the edge set up or do you regret doing it?

Funny you should ask that question today, as I just got done taking the Edge off my truck....



....because I'm taking it to the dealer tomorrow morning for service (I'd rather them not know I'm using it) It's easy enough to remove, like 10 minutes maybe. I didn't install the EGT probe, cause thats not so easy.

I like the unit. It's nice to be able to see a lot of different temps, what gear I'm in, or the fuel economy meter (which reads a couple MPG higher than actual). There's so many different things you can monitor with the Edge.

As far as the different power levels go, I've found myself using the stock setting most often. This truck really does have a lot of power, and I don't really need more. Every once in a while, I will put it on level 5 and let er rip merging on the freeway.

My MPG on the stock setting, around town during the work week, is about 15....if I'm lucky. On any other Edge power level, it drops to about 13. Because I drive about 100 miles a day, I need that extra couple MPG I get running stock.

As I said, I haven't installed the EGT probe. I watch the post turbo EGT. The highest Ive seen towing my 10K trailer is 1025 degrees. Thats up a pretty steep grade north of here, with the cruise control set at 60 mph, stock setting.

I don't really regret getting the Edge, but if I would do it again, I would probably just get the Edge Insight that just reads all the temps etc..but isn't the programmer.

i really appreciate your reply and sharing your experience with it. i had an edge programmer on my '05 dodge ctd and the instructions that came with it said not to let egt get above 1200 deg. and since i had a k&n filter and a 5" turbo-back exhaust on mine it never did. of course it didn't have as much of the emission stuff as the '14s do. also, i had my pyrometer mounted pre turbo in the exhaust manifold so i don't know how much that affected the reading.
but it sounds like their mpg improvement is a false claim.

from what my '05 ram/cummins edge w/attitude manual said, 1300*f pre turbo is a safe max EGT.
