Does anyone know how the setup works for a Rotary engine in the Apexi Power FC most of the ECU's ive sceen will have a separate table that you can use or trigger setting based on load/RPM to start the stage injections. I know Rotaries come with stage injection stock so it might be a bit different. I will try to attach the setup of my cars power FC to see if anyone can make sense of this table.

One more thing that i am also trying to understand is how the trailing ignition tables work on the power FC all i see on this table are negative and positive numbers and i am not quite sure how this works or what they use as reference for TDC or if they use the leading timing table and add subtract to that not quite sure

BTW the y axis is the load and the x axis is rpm*10 and 10000 is considerd 1atm absolute pressure = 14.7 PSIa or 0 PSIg

The trailing ignition is in °BTDC just like the leading ignition on the Power FC. (with FC Edit you can display it in split)

As for the staged injection, I still haven't figured out how it work on the Power FC, so I'm very curious about that too.

Thanks for your response Ludo ill try to put up my leading ignition table tomorrow im not familiar with the power fc but what do you mean by fc edit? How do you achieve that

FC Edit is the name of the software sold by FC datalogit (by far the most used software around the planet for the Power FC)
