    Whatever happened to the 81 mm unit they were working on?
    It would have dropped into a /2 bucket perfectly.

    Total price including postage is £20 which I think works out at about $33 USD at the moment.

    That is a great price

    Craig (now fellow ADV'r ACEWELL UK) has been MOST helpful in explaining the internal wiring of the units that I have used. I sent an email to their general "technical advice" address the other morning (east coast US time) and within hours had a concise, personal and well-thought-out response to my question. SUPER! Almost as an afterthought, I sent him a link to this thread, which Craig obviously read, and then responded to me, personally, again...

    Cannot say enough good things about the effort to provide service!!

    I posted the Acewell UK link up ^ there somewhere, but for all who are interested, here it is again:

    Acewell UK speedometers

    Airhead boxer sensor is under "speed sensors-cable drive" and is the Ace-S11 on the left side of the homepage.

    Craig thanks for helping out the customer all the way from the UK. You guys rock. Baja Designs is still brand new to the Acewell line so we are still sorting through to see what cables we are going to be offering with the units we sell. We do inlcude a universal cable with all of the Acewell computers we sell. We are hoping to have the cables listed on the website really soon. And we will take note to sell the BMW cable since its seem to be popular via this thread. The line of the Acewell units we carry is very limited so we opted to carry the one unit that does everything so the customer has the option not use certain functions... You can find the Acewell product on our website at https://www.bajadesigns.com/NET/C-407/ACEWELL

    Ummmm, I think it is much more cost effective to order direct from the UK.
    No offense Diego, but let's compare here.

    I just received the sensor, and I am about to order a speedo unit. The big thing I have noticed is that various sources list Acewell units that are compatible with the sensor (hall sensor). The only one that I have found that specifically calls out compatibility is the 3xxx series. Is there actually a list of units that will work with the mentioned sensor? The 28xx was the one I am interested in, but I would prefer to know before I jump.

    Thanks,
    Dave

    74 thru 81 R90 ish.......

    Hi wirewrkr,

    I would recommend to support your local distributor in whichever country you are in. Prices are very similar in both UK and USA. For example the ACE-2853BK in USA is $229 and in the UK our nearest model ACE-2856AB is £143+VAT and shipping. Exchange rate when paying by credit card / paypal is about $1.63 = £1.00 so that works out at $233 approx, add shipping and probably 15% duty when the parcel arrives in the USA and you're up to $278

    Once Diego adds the speed sensors to his website, I'm sure that they'll be similar prices too.

    Hi Dave,

    The general rule for Acewell computers is that if the part number displayed on the screen is underlined then it is compatible with hall sensors. For the past 3 years all units sold in the UK have been hall sensor compatible. Not sure about those sold by electrosport. Diego, are yours underlined? I can't tell from your website as the photos are stock catalog pictures.

    There is no way to tell from the part number as the same part numbers are used for both hall and non-hall versions. The only difference is where the sensor wire is soldered onto the PCB inside - hall sensor versions are soldered to the connector marked hall and non-hall sensor versions are soldered to the connector marked speed. PCB in both versions are the same.

    Say Craig,

    I think your company owes me some beers. Pretty sure I helped quite a few people buy your tacho's :p

    I love my 2853, so I keep harassing people untill they buy one too :rofl



    No, seriously, love my Acewell tacho. I still can't understand why there are so few affordable similar units for sale. Good to see that Acewell is coming with new designs, hope they include a unit in the same housing as the 2853, but with a bit more of a 'classic' display.

    First of all, there is no VAT to America.
    Secondly the 2856 with the S11 sensor added up to $192.50 on your website checkout. Plus shipping. Your checkout indicated the shipping would be around $12.00

    What ever happened the in 81mm in dash round unit that was being advertised as being available soon? I wanted that one specifically to drop in to a certain vintage German headlight bucket, but never heard any more about it.

    It was on Electrosports page when they still handled your products.
    That is one of the reasons I have been waiting to order a speedo, besides the fact that the ones offered here in the states don't drop into dashes or buckets, wish is what I need currently for a long term project.

    Sort of a dumb question, but looking at the speedo/tach combo units for my '81 G/S.

    On the tach side of the house, is it fairly accurate with the bike being a "wasted spark"
    &
    Is the sensor for the tach one of those kind that wrap around the spark plug wire? Or can it be hard wired to the coil?

    thanks

    It can be wired to the coil IF you have the beancan/solid state ignition. Otherwise, wrap around the ht sparkplug lead.

    If you look at this diagram which is also on Page 1 of this thread, it is pin #10 if you want to pick up the signal from the black wire headed into the rubber block:

    I would be happy to send this as a pdf if anybody wants it, just pm me, or email me: bpeckm at gmail dot com.

    Nuts. I just swapped it to points last year. I'll have to do some research and see if pin 10 is just an open/close function and what runs it.

    Thanks for the info.

    As an FYI, when I did that sheet, I had an early'80's bike with the electronictach, with has the ecm and hall module. The signal coming out of the ecm, to the coil, is the data-pickup for #10. Points are just a make/break to ground and don't really have a useable signal, methinks.

    Hence the "wrap 5-6 turns around the ht (spark plug) leads" per the Acewell instructions.


    :D

    Oh. Thanks, that saves me some time. Wrap it is then.

    Hi Wirewrkr

    For VAT read as the duty and sales taxes that USPS might charge you on arrival in the USA.

    ACE-2856 + ACE-S11 sensor + shipping is indeed approx $204 US Dollars, however, you are not comparing like with like!

    The ACE-2856 is a dash mount plastic case, whereas the ACE-2856AB/AP and the ACE-2853BK are billet alloy and the billet alloy case is an extra $76 which mages a total of $280 + any import duties.

    The 81mm dash mount unit has never been advertised officially as far as I know, the factory only had plans for a pod mount unit so I don't know where electrosport got that information.

    The only dash mount type are in the 2856 series here in the UK.

    Best Regards
    Craig

    Hi,

    The ACEWELL units normally work great with points, I normally suggest try connecting to the switchwire between points / ecu and coil first and if it doesn't work then try the wire wrap method

    Best Regards

    My R100S BMW engine uses points. I tried the "wrap" method and the reading on the gauge was jumpy/erratic. Went directly to the coil lead and now it reads steady and accurate.
    I love the Acewell Gauge and am more than happy with it. Mine's been in use for over a year. One thing I've found is that the angle must be proper to read it in dark conditions. I don't think it would be readable laying flat in a headlight nacelle. (?)

    Glad to hear that... did you just tap into the wire that goes from/to points and coils? That would certainly be easy to do...
