A sticker on a ECM isn't going to save a warranty. They can and will pull the file to see if it's been modified. On the GM's, a certain checksum(?) can be set to OEM parameters to match what they have set. That is immoral.. modifying something and then making your mark to say it's not been modified isn't right.. nor will it ever be right.
Again, I'm not sure what GDE is doing besides leaving a sticker on the ECM?
My 335i ECM can be checked by the dealership to see if the ECM has been modified, "which can be done" and they will void the warranty. I know because I have a tune on mine but my mechanic is super cool and doesn't report it. That being said, "the company tells you that you can't use the tune except for offroad or track usage". The fact that it doesn't throw codes or report it to emissions isn't the responsibility of the tuning company so I still don't see your argument. If with your vast legal experience you believe there to be a case contact your local AGs office (attorney general), the state AG's office, the US AGs office and the EPA. Frankly, I imagine they are going to refer you to the disclaimer that all these cats put on their websites. But what do I know, I only work in the criminal justice field daily.
"No... YOU must comply to the Law.... Period... Your tune Must Be certified to sell on Road use, The only exception is race... Period.. OE or aftermarket. You had better check the laws on why EFILive VS GDE. GDE does NOT own the device being modified, the owner does NOT own the device that's doing modifications...etc. Not only is GDE deceiving owners into thinking that their tune are green ,they are completely business bankrupt I have never seen any GDE label on any module after they molested it, Legally you need to remove that certification...No they want to make it look like its OEM. This is fooling the Maker on warranty repairs and its a gross violation on certification ... Go fine any Part, That Pumps, Rails ,Injectors, etc , Turbos TC modified form OE that does NOT have the OE maker name removed and TC Diesel SNs and label. We carry the warranty after the piece is modified , I don't expect to fool the Maker on warranty repairs. We don't F makers over for profit , and violates laws in the process. EFILive is light years ahead of anything Green death has created.
These attitudes or modding and keeping your warranty will get you flamed at almost all sites, justifiably so...
YOU will read this over and over again YOU ARE YOUR WARRANTY STATION.
256 encryption software is 2-3 years out for Road Modules, when that happens it will take years to break."
Again stop flaming and talk to your AGs office. The reason you don't is because they will tell you to take a flying f' Mr. Blow Hard. We don't have time for your petty crap.
