Hi all

Please keep all discussions related to freeSim hardware in this thread.

Current contribution phase: Collecting ideas and feedbacks on the initial requirements/design document.

Thank you

Hardware interface analysis (EMS side) Outputs: Tach signals: - crank sensor - cam sensor (secondary tach, may be multiple with independently changing phases as is the case on newer bmw engines with double vanos) - speed sensor ("a nice to have", manufacturer specific) Requirements: - Com...

Just wanted to dedicate this thread to pics/videos of hilarious custom rides

here is my entry:

I wanted to keep A and B logically separate in this context. The implementation can combine things which ever way is convenient. I can think of a way of mounting the B not at the A location, but at location most convenient for hand-manipulation (somewhere beside the shifter or steering wheel), so th...

haha this is awesome!

i bet they've also implemented the wiwntoi() function

/* this function converts a number from the written-in-words number form to the integer representation*/
int wiwntoi(char* wn){

}

Here are some of my expansion ideas: First off, i am the proponent of having all the extra (non time- and safety-critical) stuff to be on a separate CPU/MCU, to offload all the extra number crunching off the main CPU as well as remove the risk factor of the extra non-critical code somehow underminin...

Just IMO, but i think that we should save this "knock detection" energy for a more sure-shot solution like ion sensing and PPP estimation. For now let's just rely on safe tuning and making sure we use good gas.

but thats just me
