My local indy repair shop is going to do an alignment for my next week. I've also asked them to do a few simple mods using their STAR SW. Specifically, I'm having them disable the seatbelt warning chime.

There are a few others that I plan to ask about, but am not sure if they are even possible:
1) Disable navigation address entry in motion (don't think this is possible without the ~$200 VIM adapter).
2) "Permanently" disable navigation voice prompts (so I don't have to "Mute" the prompts every time a start the car or enter a new destination). May be possible?
3) Set the default drive mode to "S" instead of "C". Not sure if possible.

Can anyone comment on if these mods are even possible, and if there are other useful mods I may not have thought of?

Thanks!

How often do you drive without a seatbelt? That is just stupid. (not sure it can be disabled though)

Not sure about the navigation prompts, never use the horrible car nav lol.

Also you can not set/reprogram the default drive mode to "S" sadly .

I don't ever drive without a seatbelt. However, I do sometimes start the car while in the garage, and sit for a minute or two while I fumble around stowing my laptop bag, start the nav, etc. And I'd prefer not to have a sound and light show blaring a me at 5:00AM if I can avoid it. That one I'm quite sure is possible.

Not software related but they do make "dummy" seat belt clips that disables the seat belt chime.

Brought the car in on Monday to the local indie shop. They shut off the airbag light, and did the mod where the minimum octane rating is set to 93. The car feels...different. I think it's re-adapting.

Funnily, they couldn't shut off the stupid seatbelt warning, and had to email AutoLogic for a fix for that, which I'm still waiting on.

Never heard of that one. Did they refill your blinker fluid too?

jmueller

Wait, did you actually pay for someone to tell you they did this to your car? What did they say: "Hey, your car wont run anymore unless it detects 93 octane. We promise. It wont even start. So make sure you always put 93 in it!"

Mr. Lin

Is this only on the newer ones or am I misunderstanding what you're saying? In my 08, if I turn the car off while in S and I turn it back on, it'll be in S again. Same with C. Just not M.

INS1GNIA

It is just with the FL models, not sure about the later year PFL ones.

Mr. Lin

It is actually quite smart to have the default set to C, unless you live somewhere where your fluids can heat up very quickly. I was wondering for the longest time why my car would slam into 1st gear (obviously in S), if it was cold and my car wasn't warmed up. Then I read that you're supposed to warm the car up in C. Logical

Also.. as long as the car is not in gear, the seat belt chime does not go off. Yeah there is a little red light on the dash, but that is it.

Interesting. I swear mine always starts up in C no matter what mode I leave it in.

chrisridebike8

My 2010 PFL starts in C and it chimes and b1tches at me for like 5 seconds on startup or until my seatbelt is buckled.

nobbyv

Ha! Actually, the speculation is that by setting the min octane rating to higher than the default level (which is for 87), the car will actually advance timing just a bit, and theoretically make more power. I've never seen a dyno confirm this, but they had the car hooked up anyway, so it can't hurt.

On my '12, the mode always defaults to C every time you restart the car.

No. The chime starts going as soon as the car is started on my '12.

nobbyv

No, I actually requested they do his after researching it here and on other MB sites. They also provided screen shots showing the four settings that can be selected (Default/89/91/93).

Wow, that is weird. Mine wont chime until I put the car in gear and start moving. If I start the car without the seatbelt on it wont chime.

nobbyv

That is weird. Mine's a fairly late build '12; wonder if they changed something?

QWKSNKE

My default is 93 from the factory. How did you get a C63 that was safe to run 87?

nobbyv

You are correct; I think the default on mine was probably actually 91, not 87.

I am surprised to hear your default was 93. You verified this yourself using STAR/DAS? That doesn't really make sense, as in several parts of the country 93 isn't even readily available. I changed mine, because 93 is available everywhere I travel. I believe the fuel door states a min of 91.

QWKSNKE

91 is only for west coast bound cars I believe.

QWKSNKE

Same here
