Progress has been pretty slow because of not having the bike to take voltage readings and also the wait for parts from china is killing me.
Im currently waiting on the following:
It seems that June is gonna be a busy month 😅
Currently work has been a bit busy so ive only had very limited time and ive been mostly doing research on how all the things i want to implement work, because im learning all of this as this project progresses.
I also did some work on the power conversion and figured out how to run everything off 12V (and will work up to 24V) thats on the bike which is a relief. On the software side also, plan is to be able to control and setup the entire thing through wifi (pretty much like a gopro is controlled through a phone, although i do want to have a handlebar switch to cycle through menus and options) without the need for a usb or serial cable, and i did managed to get that working pretty good and control the dash from Windows program and through an Android App but it needs a lot of work to add all the configurations, parameters and stuff.
The main issue right now is that i dont have the bike and i cant measure sensor voltages and currents. If anyone has a B3+ and is willing to pull out a multimeter and measure some things for me youd help me a bunch! In any case i need the following:
From the dash connector:
Ignition Switch Signal (Volts when ignition is on - probably 12V)
Tachometer Pulse (Max Volts - supposed to be 0-13V? - Positive Wire)
Speed Sensor Pulse (Max Volts - supposed to be 0-5V? - Positive Wire)
From the ECU connector:
Inlet Air Pressure Sensor Signal (Probably 0-12V - Positive Wire)
N gear position wire (Should be 12V - Positive wire)
1-6 gear position wires (All are positive - No reference, possibly 12V like neutral when the corresponding gear to the wire is selected, but could also be 5V based on some service manual gibberish)
Lastly, does anyone know how many Amps is the bike outputting and how many those are being used up? Ive heard something around ~450W / 32-35A (depending on voltage and stator condition), no info on whats used when the bike is running. -- If i run out of Amperage headroom while doing all my shenanigans ill drop the light bulbs and install some LED headlights lol.

Im currently waiting on the following:
- B3+ ECU Connectors Male/Female (For making very small "in-between" harness so i can T-Wire all the sensors i need without damaging the original harness) - Should arrive Week 1-2 of June
- Dash Connectors Male/Female (Same as above plus so i can make my unit directly plug in the original dash connector) - Should arrive Week 1-2 of July (oof..)
- Automotive grade super bright / anti-glare 7" TFT screen (dont really need for the first test, but this will go on the bike on the final assembled dash) - Should arrive end of May
- Bunch of AMPSEAL connectors (for all the dash connections that are not in the OEM dash connector, gps antenna, controls, etc..) - Should arrive Week 1 of June
- Bunch of Bosch LSU 4.9 control chips (so i can wire up 5 lambda sensors - 1 per cylinder header and 1 at the midpipe) - Should arrive Week 1-2 of June
- Denso Ignition Coil connectors Male/Female (for adding in the ignition cut quickshifter later) - Should arrive Week 1 of June
- Denso Fuel Injector connectors Male/Female (Is this turning into a standalone ECU or what? Well it wasnt the plan but Ill experiment first with attempting to do additive fuel maps like a PC3 does and then well see about ditching the OEM ECU all n all, this will be after im done with all the rest though) - Should arrive Week 1 of June
