Spark Config Error
I was checking my MegaSquirt inputs and setting this morning. I wasn't getting a TPS input which I realized was because it was unplugged. After plugging in the TPS I got a configuration error:
"Too many spark outputs required with your settings"
I did not change anything this morning and have never seen this error in the months I've had these settings.
Couldn't figure out what was wrong to i decided to reloaded the firmware. I downloaded MS2-Extra 3.3.2, loaded it to the MegaSquirt and ported my TunerStudio project from 3.3.1 without issue. The error appeared to be gone.
Disconnected everything from the bench, plugged it back into the car, got the config error again.
Brought everything back inside, loaded firmware again, everything seemed cool, cycled power, config error.
I don't know what the hell is going on as the same settings were in this things for months without issue. Did I damage the MegaSquirt at some point? Doesn't seem likely to me as it appears to work fine it just randomly decided today it didn't like the settings I had in it. Anyone got any ideas?
TLDR;
Getting configuration error "Too many spark outputs required with your settings". Goes away if I change Engine Stroe/Rotary from "Rotary" to "Four-Stroke". How do I fix?

Guess what. It works now. I loaded a different .msq and reloaded my original and now everything seems to work...
I really hope this is not the kind of **** I can expect from the MegaSquirt all the time.

Tune attached. Haven't seen the issue crop up again since. Could be a TunerStudio bug.
Pay no attention to the tables as the car has never run. I think the rest of the settings should be pretty accurate though.

Car ran for the first time yesterday. Friend asked why I didn't have the rotary split table active. Turns out my "fix" was actually just me not realizing it was set to "4 stroke". Set it back to Rotary and it gave the error again.
I am now just realizing I have it set to 4 rotors. That might be an issue.
Going to set rotors to 2 tonight and see whats happens. If that fails Im going to rebuild the tune from scratch.

Switched the number of rotors to 2 and the error went away. It also cut my required fuel pulse width in half to 4.75ms. I brought squirts per engine cycle down to 1 to take required fuel back up to 9.5ms. Does this make sense or should I leave it at 2?

On second thought 9.5ms once a cycle will produce the same amount as 4.75ms twice a cycle.
Going to bump to 2600cc and keep 2 squirts per cycle instead. I wont be able to try these settings until tomorrow unfortunately.
