Hi, I am a rotary engine fan and would like to write the code for split ignition timing. I have some previous experience with engine position algorithms. If no one objects, or it is already done, I will work on it. Let me know.

Re: Split timing calculation for Rotary engine
That would be amazing
I guess the fancy way would be to fork from https://github.com/rusefi/rusefi and do it the fancy way - with all the benefits of git.
To be honest I know exactly nothing about how rotary engine should be controlled, but I am here if you would have questions/ideas/suggestions on how to hack this logic into the existing stuff.
Is there a 101 on "split timing calc" anywhere on the web?

Re: Split timing calculation for Rotary engine
Good to hear from you, and welcome along. I have some experience with experimental not wankle rotary. I have interest in learning more, and I know some people who would also enjoy learning more. Feel free to ask questions and make comments.

Re: Split timing calculation for Rotary engine
Look up Paul Yaw he has a pretty good timing diagram.
Bassis:
2 rotor engines only for now. If it works, then we can extend it to three rotors.
Distributor type position sensor with leading spark position indication and engine speed signal. Two vr freq inputs
No crank trigger type for now sorry 95 and up turbo rotarys
Two or three spark out puts logic level. There are plenty of drivers out there and I don't like high current in the ecu. That way can run stock or coil near plug with LS2 coils.
Leading plugs are driven waste spark. This has been proven on reverse engineered second generation 13 b
lead plug timing is always greater deg BTDC than trailing timing. so I'm thinking that we calculate and track the lead timing, then just subtract a split timing table value from the lead timing as the trailing plug timing. a small 8 x 8 table would provide enough detail for the split. also, we can double check to. Make sure that the trailing timing is never more DBTDC than the leading plug timing.
Only one spark event per spark plu g. sorry noMSD effect.
so I better go unzip some software file. what is the current working version. Oh I can work with subversion.

Re: Split timing calculation for Rotary engine
It would be wrong to use the zip files.
You can use subversion, but Git (which is a pain) might be a better option for a larger project like yours - this case you can have your own version of the code on the one side publicly available and you would be able to sync latest changes, on the other side not merge into main code base until it's ready to be merged.

Re: Split timing calculation for Rotary engine
hello everybody,
is there a work in progess on rotary engine ?
Best regards.

Re: Split timing calculation for Rotary engine
Not really
If you have a test mule and you can really explain it like I am five, I might be able to implement it without access to a MazdaLast visited:Thu Sep 04, 2014 12:06 am

Re: Split timing calculation for Rotary engine
If you have a test mule, and you know the crank wheel signal, the rest can probably be done reasonably easily. However it hasn't been done yet and there would be a need for some software development.

What rotary are you playing with? how is it going?
We are at the edge of rotary progress with https://github.com/rusefi/rusefi/pull/2932
