Hi all

I'm having trouble with the wiring of my Acumen CL10 Electronic Chain Oiler.
I wired it up at the same time as my Zumo, and used the CanBus plug under the dummy tank.

According to the link on here for wiring the Zumo, the No2 connection is 'pulse/speed', it's not needed for my Zumo, but it is needed for the CL10.

My CL10 doesn't work properly, it powers up fine, and purges OK, but after 1500 miles around Spain and France the guage still showed full? I had to resort to manual oiling whilst away, the exact scenario I was trying to avoid. Acumen have changed the head for me foc, but that wasn't the problem.

I've re-checked the wiring, and my diagnoses is that it isn't getting the necessary pulse telling it to squirt. I can only assume that the pulse function is not on the F800GS (maybe should have mentioned the model earlier), and although the plug is the same as the 1200, the wiring isn't? I haven't actually put a meter on to check, I'm not even sure if it would pick up a pulse?

I did ask NOG to check when they serviced it, but to no avail. The only way they thought they could get a pulse would be to break in to the ABS wiring, and that this might cause more problems than it solved!

Most modern bikes have electronic speedo's, as does the F800GS, but BMW use the same info for the ABS, I don't fancy mucking about with my brakes.

As all it needs is a pulse, I'm thinking of getting a cheap bicycle computer and just using the magnet and pick-up to send a pulse to my CL10, anyone see any problems with this? Or have you got a better idea?

Hi, hope this helps,

Just consulted the Haynes manual wiring diagram, and Pin 2 pulse is definitely connected.
Pin 2 (pulse) of the accesory socket, is wired back to pin 42 on the ZFE unit. Maybe need BMW dealer to connect laptop, and enable the pulse!

I fitted a BMW alarm to my F800 ST, it worked fine, but the clock led & indicator flash acknowledgement did not work, took it into NOG and after a little discussion, they programmed the ZFE, to tell it the alarm was there. it could be the same with the pulse output function?

Unsure how sucessful using a cycle computer pulse would be, think your oiler may need a 12 volt rising edge pulse, maybe an idea to contact Acumen.

You may be able to use the camshaft position sensor, to generate an engine speed pulse, I assume the CL10 has some form of calibration set-up routine?

Food for thought. Thanks Thomo. I did ask NOG if it needed turning on, but they said if it was fitted, then it should already be on. Maybe I should ask again.

Failing that, the camshaft sensor is an option.

Acumen have an option for bikes without electronic speedo's, so maybe find out if that is just a magnetic pulse, or 12 volt.

Ooooh this is where things get a little complex eh?

Simple answer from me is 'fraid I Dunno' ...although I think Thomo has a point about an AD being able to activate the pulse on the canbus socket wire.

Having said that, there will be a pulse signal somewhere to the speedo, and in all honesty I can't see how tapping into that could upset any apple-cart. I remember an old Dayton GPS that needed a pulse signal from my Saab - their instructions were to take a connection from that cable.

Bicycle speedo mag-pulse ..? naaah ...

I'll have a look to see if I can turn anything up ...

I don't think you will get a pulse from the speedo, the instrument cluster has pins 1 to 5.
1 & 2 are Canbus data bus pair.
3 & 4 are 12v & 0v respectively.
5 connects to the ZFE & Alarm Contol Unit (if fitted) I assume this is the output to the red led on the clocks, which doubles as Rev limit & Alarm activated indication.

It looks as though the speedo, rev counter, warning lights & onboard computer display get their data/outputs directly from the ZFE over the Canbus network, transmitted as data packets. Nicely high tech and reliable but bloody useless for tapping into .

I'm pleased I went lo-tech with a Scott oiler + lube tube which uses the free BMW chain oil, viscosity dispens-o-meter....the back of the number plate

Good luck with your Acumen, hope you get it sorted.

I think mine will use the same meter........when I get it working! Although it's looking less likely by the day

Forgive me for being a caveman, but might I suggest you fit the olde worlde version which simply relies on gravity and a bit of a suck from the airbox?

Been working without fault on mine for about 10,000 miles now...

Having forked out for the electronic one, I'd like to get it working rather than throw away and start again.

 

[Greggers]

Oooo apologies on my part for assuming there'd be a pulse into the speedo ... just as well you didn;t break out the wire cutters already! lolz ...

I'm guessing it was a 'universal' kit ... ? I'd be very tempted to talk with the manufacturers to see if they have any ideas - it can't be the first time it's happened...

Obviously don't know when you bought it, but if all else fails you may be able to return it since it doesn't work on your bike. Then you can go caveman!

Agree with Dave Ett, or if you want hi-tech, without the complication of finding a pulse or breaking into ECU or ABS circuits, if you can get a refund go for the Scottoiler eSystem, which only requires a 12v supply, uses an onboad accelerometer to sense movement, along with vibration from engine.

I bought it last June. I don't think there'd be too much of a fight if I take it back. However, having looked at the options beore buying it, I think it's the best.

If I can get it working!
