DCT safety feature for brake pedal

Rat3d ///M · 02-27-2015, 10:32 AM

The DCT has this really awesome little feature where you can't put it in gear while the car is at a standstill unless your foot is on the brake. I don't remember the E46 SMG having this, but either way, I would like to disable it. I would like to think that the brain between my ears and common sense are the only safety feature I need to ensure I don't put the car in gear while it's rolling.

Is there a way, either through coding or physically altering the vehicle to disable this feature so you can put the car in gear without your foot on the brake pedal?

It also won't let you stay in gear when the door is open.

I am unaware of any way to fix this, coding certainly doesn't do it.

The E46 SMG transmission does have this safety interlock: if the car is not moving, the brake pedal must be depressed before the transmission will shift into First or Reverse.

Similarly, if a E46 door is opened the transmission will drop out of gear and shift into Neutral.

There are no dealer or user programming options or coding language that address that OEM setup on the E46, and I have never heard of any for the E9x generation.

Its a safety feature for when there is no one in the drivers seat to stop the car being accidentally put into gear.

yeah the door open and kicking out of gear is really really annoying. !!

I think you can get round the "opening the door puts it into neutral" malarkey by keeping your seat belt on.

Maybe you are right SFP. Mine stays in 'R' when I have the door open whilst reversing, but I do keep the seat belt on.

Thanks, you learn a little something everyday - if you're lucky. Been annoyed over not been able to open door and take a look when backing up, even with PDC. Will keep the seat belt on next time and try!

Cheers

Just like any modern automatic foot has to be on brake to engage drive.

rocket_science · 03-17-2015, 09:06 AM

For what it's worth, having to hold the brake to start the car can be coded out. I coded this out on mine.

any videos of you ghost ridin' the whip?

MRV99 · 03-18-2015, 09:48 PM

If you drag the brake you will be able to open the door and not have it jump into N

Nope. I did this so I can reach through the window to start the car when I'm tuning the engine.

What kind of tuning we talking about, turning up the boost fast and furious style?

rocket_science · 03-19-2015, 12:46 AM

Since it seems that everyone's intent is on making this a joke... Yep... I'm trying to keep it right on the line where I don't cause manifold damage.

It was a semi serious question. How can you be under a modern m3 doing much of anything for tuning to require a mod to be able to turn it on from outside the car?

Because I have a lift in my garage and I dont want to lower the car all the way down to hop in just to start it.

I have a bunch of software. I run through diagnostics before race days.

Ah I too have a lift but ghetto style e46 m3 track car I can tune with duct tape and hammer.

When you run out of gas, you can also use diesel in that E46

Reminds me of when I was trying to set up the 4 carbs on a V12 E type auto...when finally setting up the tickover with the engine in gear I thought a quick blip of the throttle might help settle the tickover - even with the handbrake on the car still shot off across the hanger I was in.
