R1200 (03 07) Motronic Update Notification  
Well friends,

See this > http://www.bmwmotorrad.co.za/bikes/news/default.asp?Id=857

Good news : NOT all boxers are "affected". Mine (R12S Sept 07) is OK

Actions : call your dealer > provide the last 9 digits of your chassis ID number > BMW RDA on line web system can tell:  yes or no...

Oh good god. *headslap*

Sorry, you can't ride your bike until it connects to the server to check for updates.

PS: soon > no rider required > ECU does the ride > fortunate/sterile you...> just watch things on your holographic monitor(live at 40Mbs/sec, sound a free bonus - mind).

Interesting, nothings come through on the UK website yet. I bought my R12S in March 07 but it's from the June 06 production run. I'll call my dealer to make sure.

I wonder if it could mean better performance or better fuel consumption?

I find it odd that this effects all R1200 models though, as an R1200S would have a different fuelling map to an R1200GS, surely.

Well...Motronic updates they go "packed" (related with all R series stuff)- the current software build is 10.2. At least that's my dealer said. After talking to Big Brother > he said > relax not your case > have an espresso > adios amigos.

BMW Guru Nick (my dealer) said that the ECU upgrade potential is limited to 10 "flashes" (so to speak) - that's rather odd (I mean an EPROM chip is a passive "receiver", or not?). He said that there's absolutely no way for some increase on power/torque > has potentially to do with the way that sensors manage the fueling (the fuel 3d map to be exact).

PS1: my bike is an August 07 product.

PS2: "Issues" so far (10K miles): (1) that throttle (non linear) kinematic mechanism > Yikes!! (I like linear stuff). (2) some unpleasant vibes from 5000rpm onwards (that's due to the stressed motor), (3)that "tractor" gearbox...down shifts etc (far better than in other boxers - mind). But all in all > best real-life sports bike available anywhere.

PS3: there's a probability (quick trip to Germany) for some "scientific evaluation"...I mean doing some (track/road) miles on that HP2 Sports thing. I'll keep you informed (+ video/photos)...if I'll survive...he he.

PS4: I'm thinking for the annual pilgrimage to the Green Hell...men only and the likes...any taker?

PS5: Same BMW Guru said that the various EPROM flash stuff available here and there > the best way to ruin your bike (and void - obviously - the warranty). All that the R12S "needs" ...is some ponies more across the middle range (full HPE stuff, that is). Riding the boxer in the red = pointless in every aspect.

Curiouser and curiouser.
I find it hard to believe that one update is related to all R series bikes. As all the R1200's use exactly the same engine the only thing that makes the difference is the fuel 3d map.

Also as a fuel map would be different on an S than a GS then each models individual fuel map would effect power/torque and fuel economy as it is the fuel map that governs how much fuel is injected at any given time.

For example, a GS would require more low rev torque so the fuel map and gearing would be set up as such however an S would require a higher horsepower in the higher rev range and would have its map and gearing set up as such. Fundamentally, all the sensors are doing are telling the ECU how rich or lean to make the fuel mixture at any given time therefore directly effecting fuel economy and performance.

As I said, nothing has come up on UK info yet, but I will make enquiries.

With respect to third party EPROM flashing- it something I would never consider. However I did use a Power Commander on my previous bike, a Honda VFR800Vtec, which alters the fuelling map, not ignition timing though, without needing to flash the chip. Unfortunately they are currently unavailable for the latest BMW bikes due to the use of the Can-Bus wiring loom.

Well...think the update Motronic combo like...downloading the latest NVidia FX Quadro drivers (one "package" > FX 3400, 3450, 3700, 4500, 4600 ...inside). Or at least that's BMW Guru Nick said.

Thus I suspect that the upgrade has to do with political correctness (more lean mixtures et all) than with ponies and grunt.

I had a Ducati 998S once upon a time (horrible build quality, divine bike, 1M dollar looks). various EPROM's used...well...that was theory (Yikes!).

Other than that > what tires do you have? (I'm not that happy with my Metzeler SportTec M-1...but on the other hand they do last some miles)

Just to clarify, I'm not saying your wrong I'm just trying to understand what's going on :o)

Although the lean mixtures theory proves my point. A leaner mixture will effect exhaust emissions but it will also effect throttle response and engine power. It's all connected, could be for the better or could be for the worse.

Hopefully for the bikes it effects means better engine management and a smoother power curve. However in this day and age it could also mean flatspots in the power curve to get the bike through certain countries emissions regulations.

In answer to your tyre question, I'm currently using Michelin Pilot Road 2 through the winter but have also used Michelin Pilot Power 2. Both have been very good although the Powers do tend to square off quite quickly as I do a lot of motorway miles. Both have been excellent though. ;0)

The Pilot Power 2's got me safely round Donington Park anyway ;0)

This needs further investigation. My guess is that the updates they have to do with the way (i.e algorithm) that ECU (EPROM) does the data evaluation (received from the various sensors). Just curious: ECU instructions are written in assembly or they use C++ these days even for that?

BMW Guru Nick said: Don't expect "big" things nor noticeable curve(s) "topology" alterations (unless there's some bugs in the previous software build), just slight "adjustments" and maybe more flat spots (blame our modern times and restrictions). In any case with a full HPE system...adios flat spots.

It could be a good thing (for computer freaks, like ...erm.. us) if BMW offered some nice GUI ("read" only data - obviously) - just for digging deeper into the logic of that ECU. I'm sure that I've seen a similar W2K/XP application somewhere but I can't recall the link.

PS: thanks for the tire info.
