Steve = Using Megasquirt for ECU. How is your flight testing going? Jeff = I meant prop rpm. Using Neil's PSRU, which is 3.17. I just bumped up my idle to around 800prop (2500engine). I forgot to add, I am P-Port which causes a need for higher idle. Lynn = Idle can be that high? Usually I see rotary idle around the 10-18 range, but that is for a car. Little different with a prop on 100% of the time.
Neil = That is a nice idle. I forget, are you P-Port? What is your timing at? Dave = 35 all time? Doesn't that seem really high for rotary. Pump gas? Lynn was saying 24 degrees for 87 octane.
Hi there Matt and all
What computer is controlling your fuel and spark Matt?
Ive left the timing of the EC2 on the Renesis 4 port at Tracy’s default and haven’t changed it but was wanting to do some experimenting.
I take it that the timing setting in the EC2/3 will vary the whole timing curve over the rpm/load envelope.
Cheers
Steve Izett
Renesis 4 port EC2 EM3 RD1-C
