Cable to access Main Bike Board setup
« on: January 15, 2015, 04:39:37 PM »
For those who want to access more information about your Zero, in particular the Main Bike Board configuration one way to do this is to make a USB to OBD II cable. This will allow you to  access more diagnostic information including logs, status  and error codes. With the right access, it's possible to change things such as your speedometer calibration (this is where adjustments for the front/rear sprockets and tyre circumference are made on recent models).

Here are the parts and steps to create the cable:

Parts:
- USB to TTL cable (see photo below) with 5V (red), ground (black), tx (green) and rx (white) wires
- OBD II male plug (see photo below)

Steps:
1. Cut the connectors off the end of the green, white and black wires to expose bare wires.
2. Solder the wires to the pins on the OBDII connector as follows:
- black wire to pin 5
- white wire (RX) to pin 8
- green wire (TX) to pin 9
- red wire is not connected (+5V)
3. Plug cable in to Windows laptop and device should be recognised and driver installed successfully
4. Take note of COM port used
5. Connect cable to OBD port on bike (above the motor on Zero SR/DS/S not sure where on FX)
6. Turn on bike
7. Open Putty terminal program (freeware) and use Serial connection to connect to COM port (eg COM4) and set baud rate to 38200
8. Open connection and MBB prompt should be displayed (hit enter key if not)
9. Type help and hit enter to get a list of commands that you can run (see photos)

I thought the "vehicle speed calculation" / "distance calculation" was in the Sevcon settings? Is there a second one on the ODBII? Which models does this effect?

There are two fields if I recall in DVT which show revolutions per mile or something like that accept I think it might be in kilometers by default.  I don't yet have my diginow ODBII connector yet -_- so I cannot check myself.

The OBD II port is above the motor on the SR, DS and S models, next to the fast charge port.

Hi there,

I would like to change the speedometer calibration, because i ride 104KPH when my speedo shows 120. This is because I ride a 11cleat sprocket instead of the stock 12 cleats.... Anybody here who can give me the login to change data in the MBB?

best regards,

Christian

I know the log in for the 2012 is something like "1.21gigwatts" but I think they changed it for 2013 onwards, I don't know what that password is.

There are 3 password levels but the mentioned one will help you for the lowest level. (also for 2013...)

As much as I remember it will not allow you to change settings you need level 2 or 3 :-X

I have found informations about the FX speedo on my 2013 FX to calibrate the shown speed.
By pressing both buttons of the speedo for a few seconds it switches over into a kind of setup-mode.


Here I changed to 336-00. Now I have the correct speed displayed on the speedo. I compared it to the speed shwon on my GPS.
What I don´t know is, whats about the -00 behind the first number? (The first 3 of the number 336 was blinking, that´s the reason why it is not shown here)

And what´s about this screen here? Does anybody know this next page of the speedo?


The third page shows the digits "Li-5", which is the DIM function for the speedo. It can be changed to a lower number, and the blue LED light will be darker.

If anybody has more information about the set-up menue, i would be happy to learn more about it.

Best regards,

Christian

Ok I must be doing something wrong. I connected the wires from USB cable to ODBII pins and when I plug it in no driver is recognized or installed.

Did you have to download a driver from somewhere and if so which?

Plugging it up to the bike then the computer didn't help either.

The driver should install when you plug the cable into the PC, before you even connect it to the bike. In fact it should recognise it before you even wire it to the OBD II plug as the chip is in the USB end of the cable. Did you cut the end off a regular USB cable or use one with the bare cables on one end? A standard USB cable doesn't have the right wire combination and chip at the PC end.

http://www.amazon.com/PL2303HX-RS232-Cable-Module-Converter/dp/B008AGDTA4/ref=sr_1_1?s=electronics&ie=UTF8&qid=1423452283&sr=1-1&keywords=PL2303HX+USB+To+TTL+To+UART+RS232+COM+Cable+Module+Converter

This is the USB cable I ordered. I only cut off excess length from the cable, it still has about 6" of the USB cable which goes to about 15" of a OBDII cable for the colors / pins specified. I didn't try to connect it before soldering it up.

UPDATE:
Just started to read the reviews and found there were some counterfit chips recently. That lead me to the manufactures website here : http://www.prolific.com.tw/US/ShowProduct.aspx?p_id=225&pcid=41%E2%80%8E which lead me to the driver I needed with instructions on how to check to make sure the chip is valid.

Go figure right? Going to go plug it up to the bike now ;)

UPDATE 2:
Black putty screen :/ Enter doesn't work to bring up MBB. I use putty at work daily so I don't think it is user error ;) Will have to revisit it another night, need sleep for work tomorrow :D I tried it at 9600 (since if I went to device manager it had the baud set to that stock) and modified it there as well to 38400 ... will play with it more later.
