Re: Arduino go kart EMS
You can take some more load off the cpu by using uart receive and transmit interrupts. Take a look at "uart.c" in the zip file I posted up 6 comments above this one.

Re: load calculations
Why would ground angle change the amount of advance that the engine can tolerate? Surely the advance is just changed slightly to allow for a bit more torque up hill rather than peak hp.

Re: Arduino go kart EMS
I will give it a go thanks! I wrote a small scheduler for task scheduling and task timing. https://sourceforge.net/projects/microdispatch/ It wont be very precise for event timing but should be ok for 0.1ms resolution for fuel injection. So I use timer0 to generate a 0.1ms interrupt that ticks the s...
