Is that not a TPS wiper and an idle switch?
Yep, as far as I know.

These are quite popular in The Netherlands.
Which year is your K (I guess 1992 - 1996 ish?) and where are you from?
Late 94 (last generation). I'm from Russia.

Re: BMW K1100RS

@russian will rusefi work with 16*4 display? Also, it looks like I can get away with much smaller connector: 2 pins for power + 2 for hall input + 2 for TPS & idle switch input + 2 for ignition coils output + 2 for injector output + 1 radiator fan output + 1 fuel pump output + 4 for idle stepper out...

Re: BMW K1100RS

rusEfi kind of has an option to have igniters on the prototyping area, you just need to know if you need them or if your coils or your harness have igniters somewhere. Another term for this "logic level coil control" It's just dumb regular coils, so I need driver on board (do I have to install it m...

Re: BMW K1100RS

I do not know if there are types of knock sensors, aren't they all the same? don't know either. As I said in my first post, engine electronics isn't my area of expertise. Is it really that necessary? My current engine happily works without it. Is there is a way to connect it to rusefi? I decided to...

Re: BMW K1100RS

Thank you!
One last question before I go to sleep. Are knock sensors supported? And what types of knock sensors supported?

Re: BMW K1100RS

If original ECU reads it I am hoping rusEfi would read it as well? Ok, let's put it this way. How rusefi designed to work with crankshaft position sensor? For instance, in case of toothed wheel we can detect gap between teeths and go from there, since we know how many teeths we have we can count pu...

Re: BMW K1100RS

I haven't seen this page. Thanks! The question is will this kind of sensor work with rusefi. See, most crankshaft sensors I've seen looks like teethed wheel, while this one looks like barrel with two slits, like ignition sensor on old carburated motorcycle. I.e. aftermarket sensors look like this: h...

Re: BMW K1100RS

One area where MAP-based fuel calculation runs into trouble is with engines with "hot" intake cams. With these cams, especially at low rpms, you get a lot of the air that was sent into the cylinder sent back out- now mixed with fuel. And the pressure inside the manifold varies wildly and is no good...

Re: BMW K1100RS

Ok. Let assume I will buy full pack bundle. What else do I need? Map sensor and wide-band lambda? Where I can buy them? What models should I buy? Also, this page(https://www.tindie.com/products/russian/frankenso-04-full-bundle/) says it doesn't support IAC stepper, while this page (http://rusefi.com...

Re: BMW K1100RS

I still suggest starting with an exiting board - obviously depends if you have more time or you have more money. Once you are at a good point based on Frankenso you can make your own smaller board or improve Frankenstein. Ok, sounds reasonable. Sounds like original ECU uses TPS for ignition maps an...

Re: BMW K1100RS

Speaking of detonation. I can try to use detonation sensor, I know rusefi does not support it right now, but I can work on this and contribute to the project. As far as I understand, basic knock sensor operation goes like that: once "knock level" reaches some point, retard ignition, if there is stil...

Re: BMW K1100RS

Is that the one with the weird side-crank inline 4? Yep, exactly. One of the best BMW-motorrad engines (ironically, based on Peugeot prototype) I believe the K engines are all fuel injected, so there would have to be at least one additional sensor. Most likely either Mass Air Flow (MAF) or Manifold...

BMW K1100RS

Hi guys! I'm working on my BMW K1100RS and alongside other plans I want to convert it to rusefi. What I have: matser's degree in electronics, motorcycle with fully serviced working engine and whole lot of ambitions. What I don't have: any knowledge about custom EFI conversions, microsoft windows, dy...
