Hello engine people... I need your help.
So we are getting ready to fly this thing (RV7-A, IO-360-M1B, CS all STOCK from VANS) GARMIN G3X Touch with Red Cube FF and everything else that comes with the Garmin Engine Monitor Kit for the lyc.
We did some engine ground runs and have a few problems that may be related.
So far we did a static run up to 2570 RPM / 23,8 MAP just to see if the governor and all that worked. Engine sounds and runs smooth.
However
CHT were very hot. Spread is very close except for #1 running about 35F hotter)
EGT at about 1400-1440 across all 4.
Fuel flow was at about 11 G/H (indicated). According to the Lyc Manual the engine needs about 14G/H at this RPM
I may need an explanation on how a fuel servo works in the injector engine or where I can read about it.
How can I test the fuel flow and adjust it without running the engine? I do not want to run the engine under these bad cooling conditions for any more time than it needs to. This engine needs to fly!
Adding the boost pump did nothing for the fuel flow.
Also I am not sure if the reading from the Red Cube are accurate (located at the right before the spider on the engine). Since the fuel servo wont let a lot of fuel through without the engine running and sucking air.
Please help us: What is the procedure for setting this up correctly with the Horizontal Induction fuel servo IO360 from VANS? The thing is I do not know if I can trust any of the readings because it is all new.
