Are you refering to GDE in Europe? http://www.greendieseleurope.com/index.php/partnership Are they not the same company / partners? According to my understanding of their website, the two are partners, one tuner for the european diesel market europe, and of course our gde tuner here in the...

You'll definitely see a MPG improvement with GDE. I do a lot of city driving and I'm impressed, even with city driving, my mpg is higher than what it was when it was stock. With stock, I was getting 21 mpg with city driving, with gde, i'm pretty steady around 27-28 mpg in the city with stop...

Me neither, that's the first I've heard. GDE does a lot of field testing, they have their own ecodiesels and run testing on their own trucks before they start mucking around with other peoples ecu. I'd be interested to see valid proof of that claim and responses from GDE.

Also read the owner's manual, under REGENERATION so you have a good understanding of what is happening with a diesel particulate filter. Or ask questions here, there's lots of help.

Awesome explanation, thanks for sharing that information. That was always my concern and one of the reasons I chose GDE. A DPF can only do so many regen cycles, just like any wear and tear part, so if we can do things to reduce the number of times the DPF has to hit 1300F, the long term...

Does Passive depend on EGT or DPF temps inside? I measure both and the dpf shows 1250-1300 during regens, but the EGT never gets that hot... Maybe 800-900F during an active regen... What types of temps would it have to achieve to do a passive regen?

I have the one that either shows active or inactive, but I am not sure if that translates to active / passive (I'm assuming that's what it means??) If someone is better familiar with torque pro and understands the PID's I've posted, perhaps they have a better explanation. Usually when the DPF...

and in addition to what carlhenry said, get your ECU TUNED to shut off the egr which is probably the root cause of the fires, all this soot accumulating in the intake, stuck egr valves, overheating the intakes...

Sounds like a bad lemon. I hope it gets sorted out!!!! For your sanity. Keep us posted, there's lots to learn from everyone.

Most of the sensors I had posted in the pic, are custom made PID's, if you need the PID codes for the regen message and the dpf temp, I'd be happy to share that. With torque pro, there's a lot of common sensors you can monitor, and some that I had to custom create like regen messages, I had to...

I don't think SFT shuts off pilot injection. Do you know that for a fact? Yes both shut off EGR, but it is my understanding that only GDE shuts off the pilot injection which reduces the soot. I'd be curious to know if SFT shuts off pilot injection or not.

Agree with John, from my understanding, GDE removes pilot injection which is what reduces the soot production.

Here's a pic of one that has a leaking oil cooler, doesn't look anything like yours.

I believe what GDE means is that % soot that we see on a monitor isn't actually measuring how many grams of soot are in the DPF, but instead it looks at the pressure going into the DPF and the pressure exiting the DPF. Once the pressure drop is significant enough, (80% for gde) it triggers a...

I agree with John! When I was stock, my regen times were about 8-10 min long (approx 8-10 km of highway driving). With GDE, the time to complete a regen might be 10-12 min, nothing significantly longer than before. I've actually been able to keep a regen going in traffic or at a light (I just...

I'm in Mississauga, I see the same traffic. Honestly, I've tracked my regens and every regen occurs between 1150-1250 km with GDE, and that's with a LOT of city driving!! You can get yourself an OBDII scanner and an android app called Torque Pro, for a very low cost to monitor your regens...

Something else to consider - GDE tune is written by the engineers who work there. SFT is only sold here but is actually written by a company in Bulgaria called Optical Remap Ltd. So would you rather your truck get tuned by a company here in the USA where they test the tune on their own trucks...

from the pic, the bottle looks pretty clean to me, the ones with oil cooler leaks look really oily and dirty, you're seems pretty normal, as carlhenry said, drain it and fill it, it's probably pretty old anyway.

That's not true, if you put the heater on FRONT WINDSHEILD DEFROST with the car temp set to high heat, when you start the truck, stock will run a higher idle in the cold (usually around 1300 rpm). It's not comparable to the GDE high idle, but it does exist.

Look into the regens of SFT esp with city driving before you decide. Is the regen freq the same or better than stock, otherwise is it worth it? REGENS create a whole other set of issues like fuel dilution, dpf wear and tear, excess fuel usage and then you have to drive around endlessly to...
