Have a ZXT box on my 07 5.9 and just received the Recon ZXT gague set and installed same Saturday. During the install lost the fitting that goes into the manifold for the Pyro probe ( Don't ask, looked for over 1 hour and never did find it though ) so made one out of a brass fitting I had. (seemed to fit and install OK but not sure of the length of probe into the manifold to that leads to my questions). After setting all the parameters on my Recon as recomended and taking the truck for a test drive noticed the boost under full throttle easily got to 36-40 range and immediatly fell off, under normal throttle saw 0-6 as normal boost. EGT's bothered me and may be totally normal but have to ask. Installed in the sugessted location with the change of the fitting till I can call Jeramay and order a replacement. EGT's ran at idle around 400 degrees, quickly rose to 700-1000 under normal acelleration and droped to 500-700 range running at a steady speed but under WOT quickly excedded the 1350 setting, saw a little over 1400 a couple of times. Truck was fairly cool, hadn't been run for more than 15 minutes and will not get a chance to check till late Sunday running down the highway as this was on backroads mostly. Plan of calling your shop to check and see about ordering fitting Monday am so if you read this would appreciate your thoughts on this. Truck runs well and no hints of problems so far, 3000 miles on it.

Thanks in advance of your reply....Don

 

You must have a similar "black hole to the outer universe" in your driveway. I have one too and any important nuts, bolts, etc that I drop instantly disappear off the face of the earth. Quite frustrating really.

FWIW your boost and EGT's look perfectly normal to me.

 

Yeah numbers look good but I would leave that brasss fitting in for too long.. I'd find something stronger that can tolorate the heat.

 

I have the exact same setup (still need to install the recon) and those egt's would have to get even higher when towing my trailer (6k lbs), so they scare me. You sure thats normal. Why do you not set a boost warning on the 04.5-07 trucks in the recon?

 

Yes, those are normal EGT's. It's a lot harder to get from 1100 - 1300 than it is to go from 700 - 1000...if that makes any sense. A 6k load won't have any drastic affects on EGT's (except maybe max EGT's but how often do you floor it while towing).

 

Your numbers are fine, completely normal.

 

Its happened!

 

It's not that you don't set a boost warning, it's one of the setup parimiters for the Dodge late models that says when seting up the gague for the truck (not the warnings as that is set in another page of settings) to set boost to off, maybe because it is coming from the Map sensor instead of a boost bolt????

Really all setttings are very simple to set, just read them and follow the directions and all will be well. Took me about 2 very slow hours to install due to my caution and that did not include the time I looked for the fitting and/or drive time to the hardware store for parts.

OK further information: Drove 60 miles to sons house this afternoon. Watched temps and see 600-900 seems to be cruising range. Medium throttle pressure increases temps to 700-1100 degrees. And again at WOT 1400 and even a little higher but for very short bursts, less than 2-3 seconds would be my guess and probably shorter as I was getting worried and time stands still when worrying. And as far as when towing I have had to use deep throttle depending on what kind of incline I may have stopped on or when cruising the mountains or even just trying to pass someone on the highway so the comment to not worry could be a worry for those of us that tow frequently or long. I have to believe that this may be due to the wrong fitting for the pyro and newness of the truck, still kinda tight and that maybe it will loosen up a little after some more miles so just looking to see what others are running under similuar situations and if I am within normal ranges as compared to others OR ARE SHORT BURSTS AT 1400 DEGREES a possible problem waiting to happen. Again I don't think so from the above but inquiring minds need to know.

Oh and as far as the trailer it's a 11500# fiver about double of your 6K trailer so yes I am not stressing about it but I am a little worried as we tow from Mi to Kentucky, Tennessee, and Floridia regularly with many short trips on the weekends and sometimes long weekends.

 

I make about 7 hour runs with the 6k trailer up and down I-5 in Oregon and washington, and over the hills out to the dunes in Oregon. So what is the max temps I want to see while not on the pedal hard....1350 degrees?

Donhov, do you have an air intake or exhaust upgrades at all?

 

According to all I have read and even the suggested range from Quad it seems to be 1350 Degrees. I'm sure momentary bursts above that would be OK but don't want to run any long inclines at that temp for very long.

 

so do you have an intake or exhaust upgrade? They say it helps lower egt temps. I have an intake I made, but I dont want my exhaust to be really any louder than it already is.

 

I tested the AFE Stage II against the stock intake with back to back runs and it was good for 80* less max EGT.

 

Per my signature I have the Quad Green filter cold air intake but I have not compared it to stock as don't want to deal with it as far as changing it again.

 

EGT looks pretty normal, as does boost.

You will see that the temps stabilize in the 1350-1450deg range. If you stay in it they might even fall slightly after your tranny is locked up. The boost will keep it cool as well. I would say those numbers are in the 50-100deg over stock range and maybe not even that high on your particular truck.

1350 deg is EXTREMELY safe. Most stock 600/610 trucks will hit this easily when towing. We recommend 1350 because it is a guaranteed never to melt anything no matter what temperature.

I have run a LONG ways over 1500 degrees although I do not recommend it.

I have also run brass fittings but, I do recommend using the ones that come with the TC. This will not affect temps though.

 

Thats why my clutch slips now
