Re: FSM Syrena 105L S-31 two stroke engine EFI conversion #41

I might have made the change - https://github.com/rusefi/rusefi/commit/acd934d7621eaae77a893ee763477906e6af6d51 and https://github.com/rusefi/rusefi/commit/56257be9dee5b5e6e54aa86e20fd3a6c1b576595 Wow, that was quick! I just compiled fresh firmware and flashed testboard with it. It's working :) Che...

Re: Two stroke Efi (#14)

What is the status of this project? Finally you used MAP or TPS for engine load?

Re: FSM Syrena 105L S-31 two stroke engine EFI conversion #41

About that... Currently I use modificated rusefi firmware to sample MAP sensor only once per rev (because i have MAP sensor connected to only one cylinder -- no common collector with the other 2 cylinders): it would be a tiny fix to put this into the official branch https://github.com/rusefi/rusefi...

Re: FSM Syrena 105L S-31 two stroke engine EFI conversion #41

I plan to do my own PCB with small dimensions, but maybe at a later stage. If you do something, I could offer some help. It looks like your setup is very simple, so it probably would not take to long. Do you think you might put it inside a distributor cap or something like that? Putting all into or...

Re: FSM Syrena 105L S-31 two stroke engine EFI conversion #41

Can I please use this image for marketing purposes? It's just so.. beautiful! Oh, yes please. I know it looks funny, but it was the fastest way to build a prototype. It took me only a few hours to build it. I wanted to start testing as soon as possible :lol: I plan to do my own PCB with small dimen...

Re: FSM Syrena 105L S-31 two stroke engine EFI conversion #41

This lpc1114-based ignition - what was the signal source? was it the 36-1 wheel? Three unipolar TLE4905 hall sensors (one for each cylinder) triggered by neodymium magnet in aluminium bracket mounted at original cam. Mainly because then I wanted to fit whole pcb inside housing of the oryginal ignit...
