I think the better "safe" option would be to get two ECMs...one tuned by GDE, one stock. Easy to swap ECMs. There are moral issues involved, those are up to you. There are also cost issues involved, as a second ECM isn't cheap but good insurance in case you want to go back to stock until (unless) the flash tool becomes available.

I don't like any of the piggy back options. GDE may be biased, but I agree with their opinion in this case - you're better off doing nothing than going piggy back.

Right, and this seems reasonable, prima facie, but that scenario really doesn't tell the whole story. Specifically, FCA legally has the burden of proof to prove that the tune caused the damage.

But if your engine blows up - probably even your tranny or any other driveline component - while using it, you can bet FCA is gonna get out of fixing it under warranty if they find out about the tune.
Correct, and this is how it works in practice. They ignore their burden of proof.

I see no moral dilemma in "not giving them an excuse to void my warranty". Giving someone an excuse to rationalize abusing you is not an ethical obligation. Your spare PCM idea seems good, especially given what we've learned about what's *not* stored on it.

That's not where I see the moral issue. I see it arising if you DO damage the engine or drivetrain after the tune is installed. Let's say you drag race the Neon next to you and your transmission blows up. You then pull out the GDE tuned ECM and replace it with the stock one. Is that right even if it's the extra power of the tune that blew up your tranny? (Not that there's any way of knowing for sure if it would have happened anyway!) that's the moral issue I see. Not for me to decide except for myself.

Keep in mind, I was using a smartphone app. So there is some margin of error combined with my less than professional drag racing abilities. 😀

I agree. A proper tune will be far superior to something that just fakes out the fuel pressure and boost sensors.

Re: green diesel engineering tune

GDE is a tune for the entire engine whereas devices like Banks are a bandaid that dumps more fuel to only make more power.

Right, but I think something could still be amiss here. Their altitude runs are 1.5 and .75 seconds so the closer to sea level you get the more the GDE tune should pull over stock unless there was a very wide margin of over compensation built in by the OEM.

Also, I'm probably one of the heavier GCs. Mine is 4x4x, skid plates, Mopar rock rails and some other kit.

Re: green diesel engineering tune

A question for GDE regarding the eventual hand-held flash tuner: I know on other manufacturers' platforms, the flash tuner cannot be just plugged in and used. Sometime the ECU still has to be removed from the vehicle and manually flashed, and part of the "bench flash" process is that it tells the ECU accept flashes via the OBTII port. Is the the case with the JGC? Meaning, once the hand-held unit is available to purchase, will we also have to mail you our ECUs?

Maybe this will be the case, but hopefully not. It is an unknown at this time.

Re: green diesel engineering tune

GDE can we send you the stock ecu and you copy it to a second ecu that we purchase from you and then ship us both back with one of them having the tune on it? How much would that run?

That is the same thing as ordering the clone ecm and just keeping the clone. We do not need your stock ecm, just the following: VIN, if equipped with adaptive cruise and/or hill descent, select speed control, if is a Summit or Overland, and the injector codes.

Hope this clears it up.
