Which path should i take? Pros and cons for both please. Is it possible to have ECU tuning done and still apply JB4? Just crossed my mind if that is possible?

I have the JB4 and really like it a lot so not familiar with any other ECU tuning. With the JB4, you can change to different MAPPs and turn if off if you need to have the car serviced since the OBD cannot be read outside of MAPP 1. Supposedly non-detectable in MAPP 1 in case you are still in warranty. If you search this site you will find another thread with a lot of this same discussion that may help you.

Well let me say this is what I was told by Terry from JB4. This dumb ass (ME) took the car in for a problem that was just out of warranty and then dealer called four hours later saying they couldn't read the from the OBD and there is some kind of aftermarket software installed... So I go down and turn it off and pissed at my stupid self and forget to save after I make the changes. I guess I was too nervous to even logically think. So without saving, an hour later they still could not read the OBD so I took my car and left with my tail between my legs only to realize I had not saved the setting and it was still in MAPP 1. I took the car to another dealer after saving to MAPP 0 and there was not issues. According to JB4 MAPP 0 is not detectable but maybe it is if they dig a little... My only concern was that the dealer would try some bull shit saying my HPFP is not covered any longer because of this. So I still need to look in the system to see what comments they made when I brought it in. I know they took pics and put them in the paper file, just don't know where it went after that... Also, was told that the dealers will tell you that it will void the warranty, but I've heard form several people that they will try this but they have to prove that the actual mod caused the issue. Not sure about all of that though.

I'd love for BMS to develop some sort of hardware bypass that will allow you to just uplug the JB4 while leaving the wire packs connected (the car won't start if the JB4 isn't plugged in). Removing the JB4 is easy - removing the wire packs is a PITA.

Any service tech who is in the know can detect a JB4 by simply pressing the steering wheel buttons in the right sequence.
