That's impossible, though understandable that youd reach this conclusion after getting spooked by someone looking for the scooter. Last known scooter location before the GPS is taken out is held there online, there indefinitely, even after the scooter is disabled, until someone marks it missing or bird does something to make it go away.

Has anyone hooked the f350 up to a STLink or Arduino yet? I'm curious to know a couple things:

Where the serial wires are (which color/location) that allow the dashboard and IoT box to communicate.
The placement of the wires on the dashboard to hook it up to an STLink or Arduino to dump the firmware / burn new firmware to the chip on the dash

The serial wires should be the blue four pin connector that runs from the dashboard to the motor controller. There are only two cables that run down the tube of most m365-like scooters, one being this blue connector and the other being a brake line.

I might try this. I just got an ST link recently but aren't 100% familiar with how to use it properly. How do you modify existing firmware like that once you've dumped it off the dash?

Hiya everybody........
First of thanks to original poster and all the scootertalk peeps for the information and inspiration. I just love my new electisan/bird tank and with this kit i ended up with a fast (as far as im concerned 23mph on solid 8 inch wheels is fast enough) and decent range scooter with front and rear lights and a decent lcd user interface.

I know we are all interested in using the existing bird controller/hardware but i thought id share my after market controller conversion part list for any us/ europe/uk users.

CONTROLLER AND LCD THROTTLE DASHBOARD
i chose this controller/throttle combo as it has the same exact programmable throttle lcd as the fastest dualtron escoots and has the same wiring colours as original post motor controller.
there are cheaper motor + throttle + lcd options as ever but this thing really is a diamond to use with lots of compatible aftermarket controller options if an upgrade was needed.
features include . amps control, battery voltage selection, zero start , wheel size , motor magnet number, torque amount, power limiting, low voltage cutoff. cruise control, three speed settings......oh my

I recommend cutting the all wires one set at a time at the original bird controller as close as possible to housing then cut sheathing to display the wire colors.
the black cable and plug are the motor phase and hall sensor wires and colors match exactly to new controller wiring.
the thick black cable and large connector are for the original birds throttle, brake switch, and led which is sadly not usable due to 5v requirement. eg a pain in the ass for lazy old me

the bird brake lever switch wiring will have to be continuity (use multi meter) tested from the top three wires (red black blue) in brake lever to the bottom of the small black cable that leads from top headset to where the original controller is at the bottom to find corresponding wires. these then connect to the Hall type brake connector in my controller diagram. again you need to cut off the original small black cable with the small juliet connector controller as close as possible to the original bird controller housing.

LIGHTING
36v compatible front lights https://www.amazon.co.uk/gp/product/B0744FQ461

i chose these as the existing leds as in the bird led is five volts and runs of mainboard up top so a dc to dc covertor would be needed . i negated this by adding both rear and front lights to the black and white wires that tail from the new lcd throttle wiring loom. i can then switch the lights on and off using new throttle (hold down mode button for 2 secs)

switch bike on using generic bluetooth swith with included app or save ton of effort and use the lcd throttle to add your passcode key To view images REGISTER or LOGIN for full access.

ps here is the lcd throttle programs and guide

Press and hold the power and mode key to enter the power-on password and menu setting selection interface (S0 interface). On the S0 interface, short press the key to switch the password digits, short press the key to change the current digit value;
3.1 Enter “1111” long button to enter S1 interface, short button to switch the number of password digits, short button to change the current digit value. After the password is modified, press the long button to exit the S1 interface to the normal display interface, and save the last set password. (Note: You need to enter this password for the next boot. If the password is set to “0000”, there is no password status, and the next time you boot, you will enter the normal display interface).
3.2 Enter “6666” and press the long button to enter the program menu setting interface. In any parameter state, short button to switch parameters, short press or long button to increase or decrease the value (long button changes the value plus or minus direction, “A” is displayed on the left side) Indicates to increase the value. The left side displays “d” to decrease the value. After the modification, the short button switches to the next parameter and saves the previous parameter value. After the parameter is modified, press and hold the + button to exit the setting interface, or wait for 8 The seconds automatically exit and save the parameters.

Hello Bob Moon,

Could you please tell me what settings did you choose for the Bird Zero scooter in the throttle menu settings ?
What is the best configuration ?
For example what to choose with P7 number of speed magnets ?

Thanks


#12903
in the LCD i put these parameters and works fine.

8 inch wheel
30 magnets
and for P10 I select both options.

For the LCD version of controller 36v/350W i buy in Amazon, its came with a green cables that if you connect together, the controller find the correct way to work, and with the cables connected, the trothle can invert the rotation direction by pushing them once time.
its like an inteligent mode, i use it with random configuration of cable connections and correct it.
