Was wondering about this specific tuner as well. Looks to be a replacement for the original ECU. If I replace the original ECU, I would need to know how to prevent the garage from flashing over the GDE flash. The process of replacing the ECU is not something that I would want to do before taking my truck in for service. GDE seems to be on the right track though with regards to tuning the eco diesel motor and its supplemental equipment. Is pretty expensive as well.
I would also like to get clarification on the types of tunes and how to switch between them if it is an option.
Anyone else looked into this company and its products?
That would definitely void a warranty if the dealer had to apply a flash update and the flash could not be made or at least looked like the flash was made (even though the aftermarket ECU would reject the flash). Sounds like I may have to either wait or look at another product. I like what MoparEcoDiesel has come up with, but I would like more info regarding what the flash effects and if there are any issues with any other systems in the truck as a result of the tune before adding it to my truck. GDE would have to do the same as well. Maybe I'm just too overly cautious
This is my take, im conflicted. Kinda from another question, but kinda related to the gde.
The only thing I'd delete is the scr. Gde announced yesterday a new tune for CCV mods for cel problems, but they don't do scr delete tunes, but on the flip side Celtic tuning does the scr delete but does not do the CCV tune. On the one side I hate oil messing up my intake and valves but on the other I have this evil demon hiding in my exhaust system. I think about it every day. So for one I am super happy and content with my power level programming so I don't care about horsepower gains. 2. My truck has been mint flawless perfect with everything on the emissions side. I don't know if it's because of all my mods, my driving or the way I maintain it, but I promise you my truck is better now the way it runs than last year. 3. My new CCV kit has been doing good so far and to date @ 132000 miles I've stopped about 10 quarts of oil going through the cac. I'm going through a complete computer zero relearn on the whole emission systems monitoring system right now to see if all monitors will hit readiness all by itself with my master ccv kit. If it hits allready, I'll guarantee it and sell it. As a note, whenever a monitor is not ready for emissions testing, the entire mode 06 system is ultra ultra ultra sensitive to the slightest out of range condition. So until the system completely hits readiness you'll have a nightmare of a time getting good mileage and keeping pending codes at bay. So both Celtic and gde will turn the egr off which is great but I don't know if when they're changing those specific monitors range values if those monitors will never show ready, if that's the case I'll never be able to legally pass emissions in my state. All monitors must show ready. I am an emissions control master tech. So decisions decisions.
so if you are using the GDE tune and you truck requires some sort of flash update, can it be flashed without messing up the GDE tune. and still stay within warranty or if dealer has to check codes is it going to cause problems with warranty, i understand if you are out warranty than it not an issue, you just don't want to corrupt or erase an $800 flash, and having an extra stock ecu on hand is getting kinda expensive unless GDE would give you one? lol... and the extended warranty companys are more routinizing than factory warrants.
I am still interested in it but debating between it and the banks bullet...I like being able to pull it out if need be come smog time etc. Seems a little harder to get caught with a tuner you can pull out without a trace....
