E46 Brake Force Display Demonstration

[az3579]

A while ago, I created a video on the different stages of Brake Force Display. I finally got around to uploading it, and can be viewed here:

Nice job BP. I like knowing I have that option enabled.

Is break force display, a stock feature?

BFD is a stock feature in Europe. I think.

Very cool. Really appreciate all the time you guys put in figuring it all out.

Up to Stage 2, it is a stock feature. Stage 3 is Europe only.

Only Stage 3. Every facelift E46 sedan has Stage 2 here from the factory. On coupes/convertibles it seems to be hit or miss; I see a lot of non-M coupes/convertibles here that have the extra outer ring on the LED tails lit, so there would be no provision for additional lighting. None of the M3's I see with LED tails have that extra ring lit from the factory unless BFD is active, so I don't understand why there's a difference between the M and non-M coupes/verts.

Correct you are BP. I forgot stage 2 was standard on E46. Is it only on facelifted E46? I remember when I went to BMW Teen Driving School program they mentioned the stage 2 brake lights when the ABS hit. I thought that was awesome. When I coded my ALSZ into EV51 (Euro) I didn't see the Stage 3 being active. Oddly enough.

I see plenty of M3s on the track with their stage 2 activating when I chase them

I can't wait to see BFD stage 3 on the track.. >

Actually this is one of the few things that the US got first. All 03.5 US-spec E46s got BFD (stage 2) standard. In Europe, all the 03.5+ cars were prewired for it, but the regulatory approvals didn't come in until March 04. Adding the -BFDY switch enables it on those cars.

Stage 3 wasn't standard anywhere, at least on the E46s. And the cars weren't equipped for BFD until March 2003. Might be possible to enable it on earlier sedans (there are some cluster dependent settings that might not have been available initially), but for coupes, the wiring just isn't there until the LED tails came in.

That outer ring is lit on all of them, but it doesn't go to full bright (at least on the M3s; I don't remember normal coupes being different in that regard)

Always a fountain of knowledge, proving I have the wrong info. Thanks, I've made the corrections on the YouTube page.
With regards to the coupe/convertible facelift LED lights, I've seen quite a lot of 325Ci's here with fully lit outer rings. They lit up when braking as well. These don't appear to be enthusiast cars as I see them on a morning commute on a regular basis. I'm not sure if I saw any 330Ci's though so I can't compare.

Great video of the brake lights BP. I'll check out the detailed video when I get a chance. Do we need to code this in or it's already on?
