i'am new in this forum an the world of speeduino. At first some infos about me and sorry for my bad english
During my study of mechanical engineering and the time i was writing my bachelor thesis of a Motorcycle that runs on E100, where i was using the MS2, a college told me about Speeduino. I startet to deal with it and thought.... damn, how cool is this....
After a while, and checking all version, i decided do design my own version of the Speeduino. My focus was on old motorcycles like my Moto Guzzi Imola(350ccm/V2). Specifically to old motorcycles is that they use directly controlled ignition coils. As we all know, are the "normal" Speeduinos designed for logic coils. So i started to design a new board wich is based on The No2C with some other componets, like Ignition IGBT's and the small Arduino Mega -> Mega 2560 Pro.
This is the result....
3D Model out of KiCad, board size is 70mm wide an 78mm long
size comparison with a very well-known lighter
retrofittable functions and boards
The properties are very similar to the No2C:
TPS (checked, works fine)
CLT (checked, works fine)
IAT (checked, works fine)
02 (checked, works fine)
Hall1 & Hall2 (checked, works fine)
VR1 & VR2 via the dual conditioner Board
for Bluetooth module prepared
Fuel Pump (checked, works fine)
IDLE (on / off valve) (checked, works fine)
IDLE (stepper valve, with stepper driver)
INJ 1 (IRLZ44N) (checked, works fine)
INJ 2 (IRLZ44N) (checked, works fine)
IGN 1 (IGBT -IRGB14C40L) for direkt coils means "+12V" to the coil and "-" to ECU (checked, works fine)
IGN 2 (IGBT -IRGB14C40L) for direkt coils means "+12V" to the coil and "-" to ECU (checked, works fine)
the ground of the outputs an inputs are seperate on the board....
For the moment i checked out the funktion with ardustim, a lathe mashine and some sensors. This little thing seems to work really nice. But i actual noticed that i had to add also the outputs for VVT an Boost.
So what do the pros and experienced users say to my creation
For the future i plan to do a new version of these small board with all of the outputs an maybe a bit more stuff
an a small version with four channels
I would like to conclude with a small question:
As I read it here, a lot of work is actual put into the teensy's. Do you know if the teensy 3.5 firmware is running on Teensy 3.2?
The 3.2 ist much more powerfull as the mega but i like the size better than of 3.5/3.6
Thanks a lot for this great ecu project
