Can someone provide the text of the bulletin or a linky?

I got my car tuned right around mid-November. This would of course wipe out the tune and I'd have to get it done all over -- not likely the tuner's going to give me any discount for a do-over. What does it fix/add?

Still legal in 16 states. It's happy. It's fun. It's Happy Fun Car.

i'm going to guess on or just before November 19th, that is when the guy i talked to about it on the diablosport forum posted up "new operating system" if that helps... as for your custom tune, you'll have to talk to your tuner about that and tell them the situation to see if they can work something out for ya

can't find any more info about it on the web, and service dept at my local dealer is closed for the day!

So is this one of those deals where if you take the car in they reflash it or only if there's some sort of problem?

if you take it in for anything, oil change, wiper blades, wintergreen air freshener... they are required to hook it up and update anything that has not been updated.

ok maybe not an air freshener!

as far as I know, they only update anything if there are issues....or if you request it (in which case I've heard that dealers may try and charge you for it, since there are no problems).

I don't see a dealer automatically updating anything if you just bring you car in for an oil change...they don't stay "up" on all service bulletins for every car, and I highly doubt they check unless the customer mentions anything.

Then everyone who's even THINKING of getting a tune should get the latest OS, otherwise all the tuners will need to ensure they have both OS versions to tune your car properly. I'm sure any OS change to the ECM would obliterate any tune you had should it get updated after the fact.
