    Scan Gauge / GuzziDiag device

    in 24/7 V11

    I did mess around with using an Arduino to display the throttle position, basically it read the 5volt modified output from the TPS and displayed it on an LED display as the throttle cells.   Worked OK but I soon realised what others have found.  Going fast while looking at an LED not really that safe. I suspect that is why Cliff moved away from his bike mounted MyEcu Optimiser display.  Probably realised selling things to a careless rider in the States can lead to litigation.

    Do like your ideas, I was hoping to play around with datalogging on the cheap.  I must have a poke around and see what I can do.  How important is a rev counter on a lumbering old VTwin, especially one with a programmable Rev Limiter via Guzzidiag. I would just be happy if I could find a working Speedo!

    Ha! Yes the seat of your pants tacho works pretty well.

    My speedo is also of the "I'm waving at you" type.

    Vague-lia gauges. goto love them.

    A gps speedo is cheap to add, which gps modules coming in at under £5 these days...

    Wouldn't mind trying to see if I could compute the fuel consumption too.

    I have been learning some more about the KL interface. It's not a  simple tx/rx. The data for send and receive all goes over the K wire. There's a chip that handles all that, or you can use 4 op-amps like my cheapo USB KKL adaptor does.

    I have still not found a definative list of commands available from the 15M ECU, but what GuzziDiag offers ties up closely to the Fiat specification for the P8 ecu.

    After a bit of googling, I found the protocol for Marelli P8 ECU's is documented by Fiat. These are used in many cars as well as bikes.

    Some guys on Ford Cosworth forums have made add on gauges using the Fiat documents.  A guy on a Ducati forum is using a modified ECU with his own software running on another processor, combined with AFR sensors to play with fueling/tuning of his bike on the move!

    So there is a modest set of info that you can request from the ECU and this would be displayed on a small OLED screen.

    Adding a GPS (which are cheap these days) will give speed, or could use a mag pickup on a wheel or shaft. From that and RPM, I should also be able to show gear position.

    Will post a few pics when I get a prototype knocked up!

     

     

    If anyone is interested in the ECU document: http://download.fiatforum.bg/Diagnostic/Eobd/fiat_marelli.pdf

    Not found one specifically for the Guzzi ECU, but I believe the command and responses are similar.

    It'll be duck soup, then. Just make a cavity with a light push fit on the diameter of the bezel. Depth will be the same as the bezel.

    Yes, one of the speedometer repair shops *has* bezels, but at an exorbitant price.. he obviously wants to get paid to work on yours. <shrug>

    Duck soup? Ha! I like that. Not heard that phrase on this side of the pond. We might say "Lemon Squeezy" or "A piece of pi$$"

    If you are sure you need to disassemble it, the bezel can be removed. I machined a pocket for the bezel to fit into, but others have used a big hose clamp. The trick is to keep the bezel from deforming as you carefully go around the crimp with a tool such as a tack puller, or a specially ground screwdriver. Just keep picking up the edge slowly as you go around it. Putting it back on is just the opposite. I used a peen punch with a polished radius to slowly tap it back in and down.

    I have a big lathe and mill, so hopefully I can improvise some tooling to ease the bezel open and then push it back after. I saw someone use a bearing in the toolpost to roll the bezel back into place...

    Are new uncrimped bezels available anywhere?

    This is what Meinolf recommended to me when he sent me the map.

     

    Attached the latest BIN for the V11 with 15M. My setup includes bell-shaped air inlet ducts with snorkels removed, K&N filter, TI cans and revised throttle butterfly valves and throttle shafts.

    The base setup, and that's quite important to follow to get the best results, is:

    - TPS set to 157mV with all mechanical connectors removed and throttle completely closed

    - Both bypass screws completely closed

    - CO trim set to 0

    - Idle sync with both (if so required) throttle stop screws

    - Running sync as usual

     

    Target Lambda in my BIN is 0.88 at every breakpoint I can measure at during road driving & logging.

     

    I'd appreciate your feedback on the results.

     

    Cheers

    Meinolf



     

    Hi Antmanbee,

     

    Just to confirm, BOTH air screws closed?  I have got them both open one turn.

    TP is set to 157mV and CO to zero.

    I have MIVV cans on my bike. Not 100% what air filter is in there. (only just got the bike and didn't want to release the tank unless I really have to!)

    I would recommend trying Meinolf's V11 map for the 15M ECU. It made mine run much better than the stock map.

    I backed up my original map but it is on a different computer that I can get to later if the map that docc linked is not what you want. 

    I will give this a try! Thanks. Do I need to reset anything after loading it? CO or TPS etc?

    Google Guzzidiag,  a very clever chap in Germany has most of this covered.  If you are hoping to include GPS for data logging may well be worth getting in contact with him.

    There is a great deal of info about this app on this website.

    I will leave it to the better informed folk here to give you more help.

    Hi 68C, Yes I have already made good use of GuzziDiag!

    So imagine that but in a small unit that fits just below your clocks which you can display say any 4 or 6 PID's from the ECU. Instead of using a laptop. Don't think he's done an Android version for your phone but that would be handy too!

    Could be bluetoothed to the OBD and run off a built in battery so it's cable free.

    Just wondering if there is a Scan Gauge type device for bikes that can show some of the OBD data while on the move?

    If not, would anyone interested in one? I might try making one... Combined with a gps module to get accurate speed, it might be quite handy!

    I thought the same thing, I could just make the harness but then I realized the one side didn’t exist. Maybe it’s available now. If you find it let us know.

    I can check to see how much shipping would be for me and I might be able to ship it to you for slightly less than $120.

    I can probably 3d print the female housing if none is easily available.

    Thanks for the pics.

    Well today I got a KKL lead and despite being very cheap and not having the FTDI chip in, as advertised :-( , it worked perfectly.

    Set the TPS at 159mV, locked it off.

    Took out the air screws and cleaned them. They were very sooty...

     

    Put the balancer on. This was quite tricky to set as there is a bit of slack in the TB linkage. Need to sort that. Anyway, go it as close to balanced as I could.

    Then put GuzziDiag on and set the idle using only the lefthand throttle stop. Noticed the rev counter reads way low! At 1300rpm, it's showing about 500...

    Waited for the engine to warm up  and then set the CO. It was set at -19, so set it to 0.

     

    Just taken her out to see what's what. Bloody hell! What a difference! Really pulls now and not a hint of missfire. My previous rides were a dissapointment as the bike didn't seem to be any more powerful than the 650cc training bikes I'd been riding. Now you can really feel that extra 30hp.

    The bike runs so nice. What a transformation....

     

    So many thanks for everyone's help!

     

    Will progress getting a TPS breakout cable instead of using the pins method.

    Once you set the TPS, try the “White Knob Method” to balance throttles....copied from an older tuning thread. This method is a quick way to get your bike running well without going too deep into the brambles:

    1.

    Back off the RH throttle stop. Unless you have some super high mileage bike where everything is worn out and sloppy, using both will make you crazy.

    2.

    Open bleeds one turn each. ("Micha's method") 1 turn is almost always right. Make sure the screws and ports are nice and clean.

    3.

    Sync using white knob at idle. Like I said, some frown at this. Guess what? If they are synced at idle, it will be synced off idle.

    When the throttles are open (>3k) the white knob needs to be moved a lot to make any difference in vacuum. This is because the small adjustments the white knob makes gets lost in the large flow of air coming through, and tiny imbalances in throttle vanes will be hard to see on any kind of meter, even the expensive one I bought.

    You can turn the white knob and the throttles will appear to be in balance at higher RPM's. But they're not, which you will see when it drops to idle. Then you can use the bleeds to try to even it out, which is what I did, and then it idles worse than ever.

    In short, the ultra tiny differences in throttle openings will be revealed at idle but will be lost at higher RPM's. If the idle is balanced, then higher RPM's will be balanced too.

    Try "JB's" method, and sync the throttles at idle using the white knob. Turn 1/8 and blip throttle and let it settle. Keep doing this until it smooths out and is in balance. The idle will probably creep up as it smooths out (you can adjust this later using the LH throttle stop screw). It will never be perfect but you can get it close. Check "off idle" RPM's as you get it smoother, I bet they will be in sync too.

    Yes, this method is backwards, but since your bike runs like crap right now, why not try it? I went through ever "method" before doing it this way, and now my bike runs like a sewing machine and pulls like a locomotive...

    Thanks JB! That sounds like a plan!

    Yet Another OBD Cable arrived today, so will see if it works ok with GuzziDiag.

    Understand what you're saying about balancing at idle. I'm a m/c newbie so learning a lot. My other vehicles tend not to need much tinkering with to get running right. Usually worst case is a carb stripdown and clean to clear blocked jets etc.

    Will update when I get the TPS set, CO set and balance set.

     

    Many thanks for all the help!
