Interior 2nd Gen Most liked posts in thread: Installing seats

it is. it turns on the OC3 system

 

Wow, this has become a great thread full of comprehensive and useful information. With what SK8BRD comes up with in terms of circuit and parameters, it would make a nice meta-thread, if not a library entry.

Nathan: this kind of thread reminds me of Wikipedia--a comprehensive encyclopedic entry that can be built and edited by all. Perhaps the library could be built as a wiki in that fashion?

 

Thanks for the addition!

Just to clarify; the '05-'06 R53's also have a passenger seatbelt indicator sensor along with the occupant detector mat?

 

Yes - there are two plugs on the seatbelt itself - the indicator and the yellow pretensioner charge.

I did testing with my installed OC3 to confirm operation:

1) Seatbelt unplugged, nobody present - no occupant detected light, no ding
2) Seatbelt unplugged, person present - no occupant detected light, warning ding for seatbelt
3) Seatbelt plugged in, nobody present - no occupant detected light, no warning ding
4) Seatbelt plugged in, person present - occupant detected light ON, no warning ding

 

Hmm... would disconnecting the passenger seatbelt indicator sensor be one possible way to work around the lack of a passenger weight sensor?

In other words, the seatbelt WOULD be used by the passenger but the car wouldn't know it.

I imagine this brings up all kinds of safety concerns (would the passenger-side airbags even fire in the event of an accident, since the car doesn't think anyone's in the seat? How about the seatbelt pre-tensioner?) but I thought I'd throw it out there anyway.

 

You're missing my point... because the weight sensor wouldn't be telling the car that someone is there... as there wouldn't even be a weight sensor.

It's just a theory - remove both the weight sensor and the seat belt indicator sensor at the same time. Resistors would be used where necessary so that the car thinks the sensor is actually there, but that the device isn't being used (seat and seatbelt, accordingly).

Please note: I'm not a moron and I don't want this crazy idea to kill anyone. That's why it's a theory.

 

Well that's a show-stopper right there.

I knew that it was sophisticated (as noted very well from previous posts in this thread)... but for every "foolproof" system out there, there's an even greater fool who will find a way to defeat it! :crazy:

I like that idea... and I imagine that's how the Euro versions of our MINIs function (at least the 05/06 1st Gens).

 

All great ideas. But if I have a passenger present (it could be my 8 yr old daughter or my 45 year old friend), I want the bags to go off but you also want them to be wearing a seatbelt. So I want the car to remind them to fasten their belt with a warning chime if not connected, and I want the airbags to fire with an appropriate force -- less for my daughter and fully for my friend. I can't see any way around this other than installing the weight sensor in the racing seat and placing a shunt resistor across the seat airbag socket.
Oh by the way, I installed the belt pre-tensioner and belt-present sensor on to my Brey Krause mounts--not easy and destroyed the OEM seats getting them out, but they are present and working.

 

Spot on! Has anyone tested their setup to see if passenger side air bag is turned off for a light weight passenger? I put my fist into the passenger seat today and could get the light to come on.

 

Did you measure the resistor you used before attaching it to the wires? I only ask because resistors usually have terrible tolerances. The one you used should have had red red black bands, and another band to indicate tolerance. No band is plus or minus 20%, silver is 10%, gold is 5%. The first three bands indicate value of the resistor, last is tolerance. Here is the colors vs numbers guide

Black - 0
Brown - 1
Red - 2
Orange - 3
Yellow - 4
Green - 5
Blue - 6
Violet (Purple) - 7
Grey - 8
White - 9

basically in rainbow order, or like they taught us way back when

Bad - Black - 0
Boys - Brown - 1
Rape - Red - 2
Only - Orange - 3
Young - Yellow - 4
Girls - Green - 5
But - Blue - 6
Violet - Purple - 7
Gives - Grey - 8
Wiliingly - White - 9

So red red black would be 2.2 x ten raised to the zero power or 2.2 ohms, which depending on the manufacturing tolerance could be anywhere from 1.8 to 2.6 ohms.

 

I think a wiki model would work great for something like this. It's confusing sometimes to sort through all the posts to get to the final answer.

Also, could some of the common "everybody know this" stuff be included? I reminded of when I first started racing my sailboat. There was a whole set of mods that everyone did, but weren't written down anywhere. Someone would come on your boat, notice a problem and say "Haven't you done the split backstay mod yet?"

My Light in Sight mod comes to mind. As well as the third brake light flasher. Both things are less than five minute mods, but are good candidates for a library/common mod list.

 

The problem with a wiki at this time is more technical than anything else. The one hack out that bridges vBulletin, the software this site uses, to Mediawiki, the wiki supported by the one hack, is flawed. Hence we have a library. I have asked the Library Moderators to keep an eye on this thread and turn it into an article, cross linking the two.

As to a common mod list a sticky post for the each gens common mods that cross references the library article on the same thing should be just as effective.

I'm open to other suggestions..and lets move it to site feedback please. See http://www.motoringalliance.com/forums/site-feedback/900-wiki.html

 

yes :cornut:

 

+1 Like a charm

 

excellent!
