Currently in the process of my biggest bike project so far. I'm about to purchase one of these (they are really cheap for smartphones!):

and one of these:

fitted into a RAM MOUNT.

I'm intending to gut the instrumentation on the 1150 and replace the speedo via GPS and display the rest on the phone. The phone will also have Motronic diagnostics software. Software to be done using VB (I was a pro at VB a couple year back). Phone will also handle music so that I'll only need it and the GPS unit.

I've already gutted the instrumentation and it looks baja :thumb2.

I've already confirmed the phone is RS232 compatible and that I've enough input/output ports to capture all the data.
 
Input / Outputs

Fuel level - displayed in litres/gallons - analog [pending]
Indicators - left/right - digital [confirmed]
Motronic - 1 out, 1 in - digital [confirmed]
Temp - displayed in c//f - analog [pending]
Fuel low - unused
Neutral - unused
Oil - digital [confirmed]
Battery - digital [confirmed]
Gear - digital * 6 [pending]
Rev - displayed in 0000 format - analog [pending]

-------

1. For pending items, I need to research information on the types of inputs supplied to the original 1150 controls. The rev is straight forward, the temp and fuel gauge may be resistance based and the gear seems to have a wire for each selection.

2. The chipset can only read or write data at a given time, therefore because Motronic 2.2 is slow to return fault codes I couldn't use a timer to run a query every so often. This means manual checking for faults. That said, Motronic 2.4 has a different connection - if it will return data quickly then I will be able to poll for faults in realtime.

If you have any further info on either of these items please supply it!
 
Features, Benefits, Limitations

1. Weight reduction of several kilos.
2. Reliability possibly increased - depending on the phone. ;)
3. Remote diagnostics without BMW dealer.
4. Merge several devices - sound,phone,instruments
5. Meaningful data - phone calibrated to show real fuel/temp level and not just "bars".
6. 1150 systems do not become dependent on the phone - unlike the 1200 ;) .
 
Input / Outputs [amendment]

+ ABS *2 - digital [confirmed]
+ high beam - digital [confirmed]
 
It's a free project, but other 1150/1100/850 owners are encouraged to join my quest. :thumb

I'll need to do calibration using the standard and adv tank (which I don't have) by pouring in fuel from dry and reading the resistance/voltages.

Calibrating the temp gauge accurately might be a pain unless someone knows what each bar equates to temperature wise (then I could use lower and upper voltage boundries to work out the exact temp).

1, What weighs several kilos in the instruments ?? I doubt if the Speedo, rev counter and RID weighed half a kilo max.

An 1150 diagnostics aren't very revealing.

The adv tank would calibrate the same as a standard tank. The guage on an ADV tank only starts to register when it's down to the equivalent contents as a standard tank. i.e. when an adv tank is full, the bars in the display stay reading full until the tank is down to 20ish litres, same as a full standard tank, ten they reduce as a normal tank.

But a good project .
 
'phone'

Snoopy - sounds like one hell of a project....watching with interest!!!

However....have you ever used an spv e200? I bought a few in 2005 (just had a look in the cubboard and can't find the spare one to give you :(). I used them as part of a Sat Nav system using a bluetooth GPS sensor.

As a phone, they are almost unuseable Also....batteries are crap and the chargers normally break (see if you can hard wire in the power).

Can i recommend you take a look at the e500 - it might be better for what you are about to ask it to do.

If you need a hand linking in sat nav to your new dash, let me know.

Agreed – the SPV200 is a seriously bad phone. Been using one just for tomtom for the past 3 years – just about OK as a GPS display but as Lazer Kid says, almost unusable as a phone. Watching your project with interest though – good work:thumb
 
Looks good. You realise though you'll still need an analogue speedo - GPS ones aren't legal for MOT purposes etc?
 
No that's what I forgot to ask - MOT. I'm aware a bike speedo will pass an MOT, so why not a GPS:nenau. Any other "mandatories"?

Steptoe, those and the speedo cable and plastics weigh around the 3kg, but I expect to put at least 1kg back on. Weight is the least of the reasons for doing this. Cheers fo adv tank info.

I've not used this phone before - I presume all Microsoft based phones are crap, just like Windows :aidan . It's not going anywhere near a GPS ;) . What's so bad about it? It has to:

  • Play music
  • Pick up automatically and kill the music
  • Display stuff on screen.

And that's it.

Motronic will do info on hall sensor, air temp sensor, lambra sensor - anything else?

Presumably coz no signal=no speedo (interesting in tunnels and thick wet woods etc), and they are not actually accurate, as they don't take into account gradient (small differnces in real world perhaps, but still).

I have a feeling that stuff that isn't type certified will not do for the permanant (as opposed to trip) odometers, but would need to check that.

An instance , Air temp sensor - The diagnostics will tell you that the air temp sensor is all OK if it's working within it's parameters (lets say 0deg to 50deg).

But it won't tell you that it's reading 0 deg when it's actually 50 deg.
So you'll be told the airtemp sensor is working all OK . :augie
 
Dr Alf and I don't use the phones for Music - so we can not really comment.....although (as people love to comment with no data to back it up) i would say it is awkward to use. Nothing on the phone is logical. Simple tasks are made incredibly hard by this phone.

No real problems with the screen......

If you can get it to work (and it sounds like you will) i will treat you as even more of a SPV god.
 
Yep, really hard to use. Takes forever and a day to “boot” up – my full fat windows PC starts a lot faster! Buttons wear out fast too. Charger connection is rubbish and very hard to connect. Consumes battery life at an amazing rate. Screen is good though.
 
Carried out some more research and aborting the Microsoft version for a phone that runs Java (Sony/Symbian/Nokia). There is a much wider range of phones available (though I will need to use Java instead of VB).
 
Nippy Normans supply Touratech, Wunderlich, Desert Fox and many other makes of accessories.
