-Making a fully sequential system because of low rpm stability and response, there is a map sensor on TB which can be used as a indexer on missing crank tooth type of a signal since 1 out of every 2 turns of crank missing tooth will be intake and thus information wont be changing till the engine turns off, so ecu can take map sensor reading for first couple of revolutions and recognize which missing tooth is which phase (thus eliminating mad readings of MAP on high rpm) This is done on megasquirt type of ecu.

But im really lost in speeduino code and also i dont have a osiloscope or testing equipment to test my work and make sure i dont blow up my bike.
-Second is to make speeduino drive the fuel pump using PWM and fuel pressure sensor in closed loop thus eliminating return line to the tank which saves space which is already scarce in a drz and also improves compatibility with similar bikes. This feature is less nervous for me since i can check if its working or not on a off-the-bike test setup with all the plumbing done and checking pressure while ecu fires injectors
Gladly welcome help on those 2 subjects since i lack testing equipment and affraid to do any changes on firmware on my own as i still couldnt get my head arround which info goes where and how
