Had the CRD for a week now and it's over due for a Tune.

Keeping in mind that I am still under the Jeep powertrain warranty, should I spring for the Flash programmer tool? (2year 26K left)

I normally use my Scanguage to read codes, but I am not sure that it will read all of them.

So is it worth the $300 to be able to flash back to the stock tune prior to having warranty work done? From what I have read on GDE forum the dealer shouldn't be able to tell the tune is there.

I got one because 1) I don't care about flashing back to the stock tune (it was long ago erased by the GDE EcoTune before the tool became available) but I do care about being able to flash back to the GDE tune if a dealer ever over writes it; with the tool I can do that for a couple of other CRDs if need be and 2) I don't have a code reader and it's my understanding this tool will read and clear codes. Now all I have to do is actually use it.

I took the "old" approach of buying a second ecu for warranty reasons. I would definitely go with tuner if I had it to do again.

Another point, if I need to replace my glow plugs, I would need to load an updated GDE tune. Not dealing with the shipping would be nice.

Or does the ECO tune work with both styles of Glow plugs?

Not exactly. The original Eco tunes work with the stock ceramic 7v glow plugs but not the 5v glow plugs. The most recent Eco tune works with the new 5v glow plugs and apparently will work ok with the older 7v glow plugs (e.g. under powered glow plugs work and are safe; over powered ones are not). I'll let GDE weigh in here but if I did not have the flash tool and I had the original 7v glow plugs I'd get the EcoTune for 5v glow plugs so when/if I updated the glow plugs the tune would be all set. If I had the flash tool I'd see about getting both versions of the EcoTune and installing the 7v one until I replaced the glow plugs at which point I could upload the 5v version.

The Green Diesel tunes will function with either the 7V ceramic glow plugs or 5V metallic glow plugs. You just need to specify to us which glow plugs are in the CRD and we will tune accordingly. It is still a good idea to flash back to stock before servicing at a dealer, just in case they decide to update the code in your ECM. If they update the code version with the GDE tune installed it will render the flash tool useless and you would have to send it back to us to clear the unit.
