During ground testing/tuning, I had the engine stall and stop when I was doing some tuning. Didn't remember that it was in mode 1, pushed the button to prime and heard the injectors firing like crazy.

 

Realized that I had 'massively' flooded the engine, so I put it back in the hanger, removed a sparkplug from each rotor, ( I am not plugs up), and cranked the engine -- then squirted some oil in each rotor and turned it over a few times to make sure the apex seals were lubed, and let it sit until the next day.

 

Keep it in mode 0 unless you are doing something specific requiring other modes!

I’ll add a bit to Dave’s comment- DON”T prime your engine in MODE 1!!!

 

 

 With the engine off and mode 1 selected, pushing the program button  turns on the injector simulation function which I guarantee will flood your engine in a heart beat if your pumps are on – don’t ask me how I know.

 

 One of the good things about my “Plugs Up” engine installation is that a flooded condition is quickly overcome as the gasoline drains out the exhaust ports (on the bottom) and the plug chambers never get flooded with gasoline.  However, with a regular engine installation a flooded engine can be an aggravation.

dosent matter unless you want to "click prime the engine" in which case it must be in mode 0 to start.  General practice to keep it in more zero to avoid changining something on accident.

I am just starting to tune my EC2 system and feel pretty sure I need to adjust the injector flow (mode 3). Should I always start in Mode Zero, then switch to Mode 3?  Or can I start in Mode 3 and begin injector adjustment right away?

Thanks,
