Just to be clear.

GDE has 4 tunes for the ECM
Eco Tune. Operates with stock F37 TC (torque converter)
Full torque Eco tune same as above has more torque for TC's that can take it.
HOT tune. Balls to the walls.
Turbo tune that's for their turbo upgrade.

I originally got the Eco tune and original TC
When my TC was updated I upgraded to the "full torque Eco" tune that I'm very happy with :JEEPIN:

If I wanted an all out hot rod I would not have gotten a Liberty :SOMBRERO:

To which I will add the GDE Stage II turbo (a big improvement over stock) requires the turbo tune but there is a discount in cost of the pkg if you already have a GDE tune AND a torque convertor upgrade from stock is an absolute essential. I drove a stock TC with the EcoTune for a couple of years, including some towing, without a hint of shudder but once I installed the new turbo I got shudder within the 1st 50' of a full throttle run. Needless to say I drove gently from geordi's back to Tally and then a couple of weeks later to SunCoast where Ron and company installed my SunCoast TC.

Hey papaindigo, do you experience ANY shudder/vibration with the stage II and Suncoast? My Euro-TC is way better than stock, but it doesn't feel butter smooth with full throttle upon lock up with just the ECO tune, so I am worried about upgrading tunes even with the Euro TC.

I've had mine in for a few weeks now, works great!

8.2L per 100km is my typical average for the tank for daily driving, mostly on 100km roads doing 105 with lots of 50km small towns and some city driving and 3-4 min cool downs.

more power forsure

Gas gauge is not totally fixed but better, 500km for the first 1/2 and 350 for the last half.

Main thing, NO EGR!! so no issue down the road with the turbo.

So far I am really liking my GDE eco tune. I only have two compaints. The first one is no more black smoke on full on throttle... You know where you have a guy in a mercedes convertible just on your rear end type... The second is the gas guage... I am at 1/8 of a tank and I start going through the OHH crap moves... Find a station that has diesel and fill up with 16 gallons... Wish I could have known better.. II had 4.5 gallons to go!!!! I had all those ohhh crap moments going thru my head of that I ran out of diesel and would have to have an excorcism done on the liberty to have her run again.

arengant - no shudder but then I'm not one to hammer my throttle often other than to keep turbo vanes nice and clean and I don't tow a lot. I like the feel of the Stage II turbo/Suncoast combo but IIRC GDE is running the Stage II with the Euro with no issues. Honestly probably the main reason I went with Suncoast is they are close, would do the install, and would warranty the new torque convertor. I did find out later that my local DCJ dealer, pretty good one, has installed Suncoasts on several Dodge trucks so they probably could have done the work without the drive to Ft. Walton but then I got to chat a bit with Ron and see some of their facility.

This is what Keith at GDE said about the Fuel-Gauge re-cal. What year is your CRD?

"The fuel gauge adjustment works very well on the 2005 CRD and it does not do anything for the 2006 due to a change in the CAN bus communication, strange issue."

One of the reasons I bought a CRD was because of the tune as well

what are you guys cleaning out your vgt with, any kind of spray on the market? besides showering down on the skinny pedal every now and then haha
and has anyone tried to stack an mp-8 powerplay or anything else with the gde tunes with positive feedback?

IMHO, I wouldn't stack anything else on this engine once you have a GDE tune. GDE has pretty much optimized what the components of our engine can do over a long period of time. Anything else will just go against those safety measures and shorten longevity.

I've never been a fan of glow plugs. from my understanding thats the only big weak link in these engines. once that issue is taken care of and some regular maintenance items i think it would be fine. i mean from what ive seen you cant really order 300 hp injectors for these little things. at the moment i need to focus on gauges. and im looking for input on what exactly would be the best bang for the buck. this is a common rail with CAN system iirc so there should be plenty of info coming through the obd2 vs what i see on my 99 cummins which is almost nothing. maybe ill just get a scan gauge 2 and forget the rest. as long as i have a tranny temp gauge ill be happy

You better read up on the CRD and scan gauge compatability :grim:

geordi · **Posted:** Sat Sep 08, 2012 5:06 pm

Not just the ScanGauge issues... You are sadly mistaken if you think the plugs are the weak point. Frankly, they are probably LAST on that fairly long list.

Let me see...
Torque converter, turbo oil supply, turbo size for the engine, oil pressure sensor location, EGR, FCV, MAF, MAP, CCV... Lifter / rocker design that fails at some unknown but moderate mileage... Random hacked-together computer system that is not standards-compliant which makes devices like the ScanGauge crash the TCM out of gear at high speed... Finally, the glow plugs, which have been solved by using the Etecno metal plugs.

The biggest problems: clueless dealers and ZERO support from Chrysler because they would rather that we all just went away. (but bought another MOPAR to replace it)

Many of these problems have solutions that can be found here, the rest (like the lifters) have solutions under research currently by the members here.

I WISH the glow plugs were the only weak point.

i was referring to the block itself. but thats good info. i would call a decent size block leak a major problem for me. chrystler sucks booty. im obviously gone alot being military, so when i had a problem and didnt have the time, to make a long story short, i had to get a tow truck come DRIVE my jeep onto a tow truck(just watching that was enough to make me have very dark thoughts haha) take it to the dealership, and quote me 50 bucks for replacing the belt tensioner. then call me 20 minutes later and told me the 50 dollar charge was now a 650 dollar charge because they didnt realize it was a DIESEL and they would have to get the "top diesel mechanic in the southeast" to come work on my stinky poo. obviously the tensioner has nothing to do with the type of fuel the vehicle uses. needless to say i was glad my soon following assignment would allow me to relieve some stress

i guess people can say sh--it on tv but not on here.... amazing

Yes it is amazing that some still enforce basic common courtesies and respect. I personally like it. As a military member you should embrace it as it is a common core value.

well in fact, censorship has nothing whatsoever to do with courtesy OR respect. and it most definitely does not have anything to do with core values. I'm glad that MY RSOs are intelligent enough to know that hahaha.

If you can't handle people using the honest language to explain things like how much of a Charlie-fox this engine design is, or the actual definition of fubar bothers you... How will you deal with the infinitely worse disrespect of high velocity metallic insults to your pride?

I have the utmost respect for anyone in our armed forces, and while I have not served, my relatives have. I can say for certain that a little bit of accurate and colorful description now and then is not a detraction from their character, no matter how blue the language.

The world is a messy place. I won't allow myself to be offended by mere words, there are far more important things to be concerned about in life.

Now back to our regularly scheduled pishing and kvetching about all things MOPAR.

It's not Censorship it's using appropriate language in a public forum. Want to use a colorful word, get a thesaurus. The military does not conduct business using these type of words. Not in my 22 years of service, not now as a DA-C and not during the 42 years I have been around the military.

So far I have been very pleased with the GDE tune on a new engine. Every 1000 miles it seems to get better and better.

this is NOT to my understanding a military site. i am also not understanding why you have rso on your signature. this site has nothing to do with weapons. you need to look up the word censorship. and living in Virginia of all places you should know. they still give fines to people that utilize their first amendment right.

back to the forum. does anyone here have actual dyno or quarter mile numbers from any of the green tunes?

jinstall · **Posted:** Wed Sep 12, 2012 9:51 pm

I have a background in military public affairs. I am well versed in censorship.

I have had no time to get to the track and see what my new 1/8 mile times are with the GDE tune.
