The only option our ecu's have for connecting via bluetooth would be using a bluetooth OBD2 dongle.  Im not sure if there are some that are capable of pairing with two devices.  OBD2 can also be quite slow.

A better option maybe something like RaceCapture Track:  https://www.autosportlabs.com/wp-content/uploads/2018/08/RaceCapture_Track-MK2-product-brief.pdf

This is a device that connects to the ECU via CAN bus and then to your phone/tablet via wifi.  The connected phone or tablet is used as your dash.  At the same time if your phone/tablet has an internet connection (sim card), it also streams ECU and performance data out to a cloud-based website.  Your mechanic in the pits can then use his phone/tablet/laptop in the pits and view all of that data.

Have been reading owners manual and playing with software for a couple of days now. Most of the questions I have found answers now and keep reading. More I read, more questions come out.. :-)

Came in my mind, that if I would use Android/Tablet via Bluetooth, is it possible to use two tablets at same time? So one would be as dash and with one my mechanic could watch temperatures, pressures etc. in starting line. Off course connection for mechanics tab would be lost at some point of the track. More likely this would be just nice add/show off, but maybe it could be useful at some point.. Dash could also connected with wire if possible. 

I use USB over wifi for controlling my ECU remotely (I plan to install the Link ECU in the boot next to the engine so no long USB wires).  I bought one of these from amazon which work great and are cheap :-

The hardware then needs reflashing with the virtual USB software:-

Powered with a 12V micro USB adapter, this gives you USB over WiFi, which should be significantly longer range than bluetooth.  The Virtual firmware is available on a few different platforms so it may be possible to extend the range even further.

So, if I'm comparing Fury and Thunder, meaningful differences would be:

-Thermocouples -> I need 4 so probably need to get EGT to can anyway

-2 Lamdas -> I think need only one anyway

- Sensor for g-force -> comes possibly with the dash or with the RaceCapture-device if I decide to get one.   

 

Is there any reason why I should choose Thunder over Fury?  It has got more inputs and outputs, but Fury seems to have enough. 

Do I get more accurate info with Thunders own accelorometer? Do I get more precise ... something?

Yeah, I suspect the Thunder is probably overkill for what you are doing.  It is also quite a large box to fit on a bike.

Or you can use a cheap analog accelerometer.  The nice thing about the internal accelerometer in the Thunder is it has adjustable filtering (to filter out "vibration noise"), whereas if you connected one to an analog input you wouldn't have that - but you can use a resistor-capacitor filter to damp it down a little if needed.  As you say though it is also possible your dash or logger may have that functionality.

The only other feature that may be relevant on the Thunder is there are 4 digital inputs that are much higher speed than the Fury.  The Fury DI's are limited to about 500Hz, the Thunder HS DI's about 6500Hz.  This would probably only be relevant if you had a wheel speed sensor with a high tooth count.

And cheap analog accelorometer I can more easily assembly with some rubber bands etc. to  damp some vibration. 

I think hall sensors would be the right ones to measure wheel speed. Don't know yet how we are going to build that, but I think we make tooth count to fit with sensor. 

One idea came in my mind thinking this.. It might be possible to measure lock-up actions with hall sensor. If lock-up "claws" would work as tooths, you could see RPMs where first set is out. And when second is coming along, it will douple the "tooths" (in 2-stage lock-up). There speed is fast, but its only informative, so I don't know if it makes big difference or if its worth to choose thunder over fury with this cause. I really don't know if it is even possible to use hall sensor like this. Just crossed my mind.. :-)
