Trip / MPG Computer

Will I have to change the settings in mine. Its a K1100.

Depends what the injectors and fuel pressures are. According to euromotoelectrics, it looks like the injectors flow 150.8 cc/minute, which works out to 3.765×10^8 microseconds per gallon for the whole engine.

AFIK the pressure and injectors are as from the factory, is it the same as K100.

Is that for a 4 valve or a 2 valve. If that is the case, there are 3 or 4, 133 cc per minute  (at 2.5 bar) injectors.

Its a 16V  K1100LT

This seems to be the right number. Put it in, and run it for a tank. See how the numbers compare to the actual ones.

Thanks will do

Rick, could you report back results to this thread after you test? I'll need to make the same entry when I get around to the install.

I will get back with the results but it will be a few weeks away.
Three weeks ago I took a fall carring some fire wood and broke my left arm about half way from wrist to elbow so have a cast up to my armpit.
As you can gather I am a bit limited in what I can do. Not sure how much longer it will be as the break was a bit spiral as the doc put it and so it can take some time to heal.
The real bad part is that it is the best riding weather all year at this time.

Ouch!  Sorry to hear of your fall, Rick.  I hope all goes well (and quick) on the recovery!

[leecow]

Yikes, rest easy and heal well!

[leecow]

Starting to ponder clean installation options without thinking too much about implementation details for now. Something like this would be clean.

I've been pondering this very question too.  I have changed out the OEM handlebar on my K100RS and replaced it with one from a K1100RS.  This is slightly wider, and there are gaps between the switch pods and the bar cover.  I'm wondering if I could us something like a GPS mount there to hold the computer.  However, I don't know sh*t about those, not ever owning a GSP.  Can someone recommend what brand/model may be suited for this application?
TIA

I just found this searching for MPGuino projects on BMW motorcycles.
This is a very interesting project and I'd like to implement it on my bike. It's not a K, but an R (1997 R850RT ex-Dutch police).
I want to make more of a bike-computer, but the mileage stuff is great, being real time and all. I'd want to implement more stuff like a data logger feature which records things like position and sensor data from a accelerometer.

Reason I post here (and revive a sleeping thread) is that I'd like to know if this would work on a R. Is het injection system very differen? What data do I need to know if I was to adapt the fuel monitor system to work on the R..RT.

My version might look more like the scooterputer ;)

Cool Project. The fuel system is identical as far as the computer is concerned. It just looks for pulsed voltage.


You would need to find the conditioned signal from the speedometer.

Ok, thanks for that. I'll have to pop the dash and take some readings then... ;)

Hello everyone,

I am new to the forum. I have just bought a 1989 K100RS and waiting for it to be delivered from Adelaide to Sydney (Australia). I have been browsing the forums to get more familiar with the K bikes. I had a '84 K100RS for a short while in the '90s.

Anyway, I was following this thread with great interest, and it suddenly ends at this point. Was the concept developed further, perhaps continued on another thread?

If anyone has a link to this project, or something similar, I would greatly appreciate it.

Kind regards,

Chris

Right here. I'm a bit backlogged though, since I've been busy with work.
