I agree with the M2W manufacturer and others here that M2W is not the cause of the OP's problem. M2W is a fused remote controlled switch. Electrically it has the same effect as removing/re-installing the fuse.
pscott -- Its been a few days, any updates from the dealer? Did they try to charge you for the work?

Sure hope you find out what the root cause of the problems is and get it fixed. Also hope you don't have to get stuck with a large repair bill.

It does affect launch control. Meaning, if the MTW switch is opening the circuit, the launch control will not work on many vettes (mine included).
OP, I had a similar issue with my 2008, and the dealer claimed the MTW switch was causing issues. The thing is, the NPP module does interact with many electronic systems on the vette, which is a poor design in my opinion. (I'm a registered professional engineer, electrical/electronic background, and I verified what they were saying with engineers from Bowling Green too). My 2008 had so many issues, it qualified for a buyback, another long story.
But, to prove that the MTW was not creating my computer issue(s), I had to leave it out every time I took it to the dealer, until they tested/replaced everything related to the problems.
My advice would be to simplify the troubleshooting, and leave it out of the vette, until you get your issues resolved.

After seeing this thread this morning I contacted the Mfg this morning and this is their response:
From the Manufacture: We can tell you that with over 30,000 units in use as far back as 2006 that these claims are ridiculous. Not only is mild2wild installed by over 30 GM dealers on new deliveries but was built after consulting with the GM engineer had that designed the Z06 exhaust back in 2006. Hooking up to a central ground cannot cause any computer failures and even if somehow there was a short mild2wild is fuse protected. All mild2wild does is complete or disconnect the 12v traveling to the exhaust circuit. It’s sad that GM has techs that clearly don’t know what they are doing and look to blame any aftermarket part. If you like I would be happy to speak to the service manager.

I haven't had access to a computer and couldn't check in. I hadn't heard anything about my car until this afternoon. The service department called and said that they had replaced the BCM again (number 2) and thought that they had it. Took it for a test drive and BAM! Everything shorted out again. They are on the phone with GM again and GM seems to think now that it is a bad BCMV (?) I think is what they called it. They think it is shorting out everything. NO MORE mention of the M2W! They were all over the M2W before, saying it was the culprit. Well, this time it happened with just a fuse in the fuse box. They didn't even bring up the M2W. I feel vindicated, but my car still isn't fixed and it has been over 2 weeks. Also, the way I see it, they owe me $90.00 for my M2W that was destroyed by the car. I probably won't bring it up, because I just want my car back, fixed and without owing the dealership my firstborn.
I will keep everyone up to date on what is going on as I get the info and have access to a computer.
Thank you all again!!!!

I had abs, tics issues on my previous ZR1. Caused me to crash the car while driving down the highway. GM sent engineers who were able to rid the PCM of all evidence. Don't mess around with the malfunctions, it can be very serious when the active handling engage while you are crushing at 65 mph and the car thinks you're out of control.

My friend that works there told me this morning that the reason that the dealer doesn't have any 2014 vetts now and won't get any until next year is because the dealer doesn't have any certified Corvette techs or certified Corvette salesman. How warm and fuzzy does that make you?

Frankly, I wouldn't care if I had to travel 50 miles to find a qualified dealer.
Sounds like your dealer is clueless, and you don't want clueless, experimenting, and schooling on your car.

Still no news on the repairs. I don't know if there is dealership anywhere nearby that has a certified Vette Tech, but even if there was, my car won't even start anymore. If there is no progess soon, I will have to do something else. I know I won't hear anything over the weekend. I will keep you posted.......

I'd certainly be very upset by all this. Not much we can say except, hang in there.
A year or two from now, you'll most likely tell this story, and be laughing about it.

VERY INTERESTING! I have an "09 that suffered a similar malfunction last spring. (See my thread titled "Bad News from My Car?" posted April 1, 2013 that gives all the gory details of my fun with the local dealer - ultimately the Body Control Module was replaced on my dime, and the Throttle Body and Engine Control Modules were both replaced under the powertrain warranty.) Note that I had installed a Mild 2 Wild switch shortly after purchasing the car back in Aug. '08.
About one year prior to the malfunction, I had the local Chevy dealer install a Chevy Personal Audio Link ("PAL") enabling the playing of an ipod through the car's stereo. When the engine repair was completed, the service manager advised that this part was "probably" the cause of the problem and recommended its removal as part of the repair - which I did. He also advised that they discovered the Mild 2 Wild switch during diagnosis of the problem, but did not think it caused the driveability problems. ??!!??
I am neither an electronics expert nor a mechanic, but it seems to me that the PAL rather than the M2W caused my problem, and that your M2W probably did not cause yours. In my opinion, all this goes to show that the dealership service departments are really only guessing at the cause of such difficulties and their repair efforts are "hit or miss."
Most important, today my car drives fine. However, lately I have noticed that the clock in the radio/nav system will periodically gain or lose 1 hour on its own - which I can only hope is not a side effect of all the computer related problems......I guess time will tell.....

Electronics are sometimes finicky. There are a variety of reasons why they can and will be, form loose wires, to loose components on a board, to interference, to programming conflicts. We sell a lot of equipment with electronics on board, and have seen problems come up after a day, week ,month or even years of use, with no mods done.
In one case we found an issue with a piece of equipment whereby it was faulting randomly for seemingly no reason. After watching it with three different laptops plugged in looking at different parts of the program, it was found that there were two boards communicating. Every now and then one board would miss a communication from the other. When this occurred, the other would see no communication and stop the control loops.
As mentioned, if a guy isn't trained to do, and actually does troubleshooting of this kind, it can be a goose chase. Often they will point to an issue to get the device out of their site, only to find out later they were wrong. What you need is a troubleshooter, not a parts changer. These are two VERY different people.

I have serious doubts that M2W switch is source of problem Any issues with switch should be grounded out and not cause problem with other electronics. I too have M2W on my car please keep us posted and good luck
