shut down sequence for ULpower 350is

What is the appropriate shut down sequence for the 350iS?  I have a Dynon sky view.  Here is the sequence I'm currently using:  

step 1: turn off switches for radio, lights, Dynon skyview

step 2: turn key to off (kills engine)

step 3: turn off switch for ECU

step 3: turn off switch for fuel pump

step 4: turn off master switch

I assume this leaves pressure in the fuel system forward of the fuel pumps.  Would it be better to shut the fuel pump off first to relieve the pressure?  

thanks,

bt

Hi Brian, On mine, I shut down the ECU to kill the engine because  the ECU pump will stop at the same time while the engine winds down. I think that also kills the ignition as well. Tom

Yep, turn off the ECU,  then everything else in whatever order you want.   cheers, ,,,,,,  Lynn

I shut the engine down in this order:
ECU
fuel pump
batt/master
ignitions

I shut down the fuel pump and let the engine die as it uses the fuel in the line so I end up with little to no residual fuel pressure in the system.

Then ECU. all switches for lights, radio etc on Composite Design UL engine power panel and finally master.
