Has anyone done all the deletes and have GDE TUNE?

As the title states has anyone done all the deletes,egr,dpf,def, and have the GDE tune?

I ask because I just had my first cat replacement done on this past Monday 3/6/16 @31,800 miles and all current programing updates.

My last 3200 mile road trip I got the service engine soon light on "Solid" since i was pulling my 16ft trailer with 5k lbs on it. I went to first dealer I could find, they checked all the codes since I did not have my own reader with me. They told me I needed to have my cat replaced asap. They reset the code and did all programing updates.This helped for short term! Since I was traveling they told me I should contact my local home town dealer.

I have excellent dealer,when I called them still 1 week from returning home they preordered all the parts for the recall. Surprising they did not break any sensors and all is well so far. Just got it back yesterday. Will let ya'll know how it goes from here on.

My local dealer is mod friendly and when I talked to the service mgr (neighbor) he suggested I wait until I am out of warranty just to make sure there will be no blow back from MFG incase the motor goes tits up between now and when factory warranty is up.

I would like to start to collect all the parts necessary to make my JEEP into "OFF ROAD" ready status haha, as time and budget allow.

I plan on buying a new second ecm to hold the tune so I can easily swap as needed when having Jeep serviced, unless GDE will soon give us reflash by owner option by PC .

I would like to know where to source these parts that you have used.

I would like to know how your Jeep preforms since the upgrades, mileage and any furthers issues you may have had since?

Since you Australian owners of ECO's never had all the Air polution crap on you vehicles like the USA what problems are you having?

26-27 in town, 34+ highway. i also got the cb intercooler and pipes. the down pipe is coming soon as well. i have all the deletes, but the dpf. i will get the downpipe and send my ecm back to GDE for that delete as well. i heard that you will see 40mpg. i would not hesitate to do this. i too got an extra ecm, and think its well worth it.

Re: Has anyone done all the deletes and have GDE TUNE?

I just ordered the Offroad Pipe from CB and as soon as I get my jeep back with the new heads installed, hopefully next week, I'll be getting the GDE Offroad Tune. I want to make sure it runs well of course and give it a good dive before I do it but I also want to keep the EGR miles to a minimum. I'd love to see 40mpg but I'm not that optimistic. GDE says there are minimal gains for power and economy and I wonder if that's to cover themselves legally. They probably didn't road test it because they legally can't thus they have no road data. I do hope to see more than the 1%-2% GDE says you'll see and I would expect to without the restrictive DPF but we shall see. I have an average of 27 mpg and I'll post updates on here of my "Offroad" mileage as I test it. We have alot of flat smooth "off hughway" roads here wink*wink* and my commute is made upon them.

They absolutely can test it. There isn't any need. It's the same tune with the DPF turned off. DEF and EGR are already turned off in the hot tune. If it wasn't "legal" to test it, then they couldn't post stats from the hot tune by that logic since EGR is federally mandated and it is shut off in the hot tune. The only fuel economy gain you'd see is from a lack of a regen cycle.

Re: Has anyone done all the deletes and have GDE TUNE?

love the GDE product. i use distilled water instead of def fluid during the warmer months. GDE says that a downpipe doesn't do anything, or air filter and exhaust don't do anything. i do not agree at all. with a downpipe and exhaust you will see a big improvement in mpg.

i added a 'dry' drop in filter (afe) and a custom cat back exhaust. yes, there is an improvement. i also added the CB engineering intercooler and pipes, that also makes a difference.

i will be ordering the downpipe soon and will send my ecm back to GDE for the delete. i will add the banks intake manifold as well. future plans are to twin it anyway...

I see your point about the EGR being federally mandated but there must be something more to it than that, they have to label the Offroad Tune as "Offroad only" because it is illegal to sell it otherwise.

Also the hot tune does not "turn off" the DEF, it aligns the usage so that the fill interval always coincides with the oil change interval. This is clearly stated on their website. There is also data showing that with the hot tune and the EGR disabled, the ecodiesel still passes emissions tests so maybe that's how they get around it. I know a few guys with 09ish Cummings Rams that have done DPF deletes and gained several MPGs over the other tunes that leave the DPF in place. I'm not saying the results will be the same, I'm just hoping they will. I understand there should be slight gains sure to lack of regens. I'll be sure to post my results.

If you've talked to the guys at GDE they do turn the DEF off. Its kept in an open loop which essentially is just injecting DEF without any measurement of the NOx being produced. So instead of injecting more or less DEF based on the amount of NOx being produced, it just injects. Which is why you can use distilled water instead of exhaust fluid. It's not actively reducing the way it's designed to. It might still reduce it, but if it's stock software it's reducing based on the amount present in the exhaust.

When you get codes for "reductant below threshold" like P20EE, it's because the DEF isn't reducing the NOx levels enough. That's why folks with the GDE Tune don't have issues with the SCR white washing and needing to be replaced.

Interesting. Thanks for that info. I'll still be doing the full delete and posting my results. I've seen two different guys with rams and PPEI deletes post their results. One said he got 7mpg overall increase and the other said he gets about 35mpg average. I trust GDE more than PPEI and I'll be plenty happy with similar results. I'll be happy just to disable the EGR, truth be told.

Amen to trusting GDE more. Lol. I have the hot tune now and I'm plenty happy. If I lived in a state where I could get away with it I'd run a straight pipe. I did a cleaning of the intake manifold before my last oil change and it would have been a lot worse without the EGR disabled

Nice. As I stated before, my jeep is in for the cylinder head TSB and I asked them to clean the manifold while they're at it. They tried to tell me that it shouldn't need it. I laughed at them and said "do me a favor and look at it, I'm sure you'll feel otherwise." I basically had to force them to do the TSB. I've got about 85k miles on it I'm sure it's pretty bad in there.
