Thanks Ed.

That looks extremely helpful. It appears to have a PC interface
to read out the map to a PC. Is that correct?

As I recall you have a 72 dia. 88 pitch Performance wood prop
and a 2.85 PSRU on your RV6.

What is the top speed at what engine RPM?
Gross weight of your airplane?
Max climb rate in FPM?
Cruise RPM and fuel burn?

Well, sort of, I have a function on the EFISM instrument that I can use to
store the fuel map imported (for display as you saw in the photo)  from the
EC2 into it's (the EFISM) EEPROM.  Then using the same programmer that I
used to program the EFISM chip, I can read the EEPROM data using my PC after
I have stored it (requires bringing the unit home).  That is what you got.

I have a 74 x88 (was originally 76 x88) performance Wooden Fixed pitch prop
with my 2.85:1 ratio PSRU.

Top speed is 202 MPH (+/- 3 MPH) TAS.  However, my top 4 speeds averaged
together (more reliable) = 195.5 MPH TAS at average of 6500 rpm.  However, I
normally fly at 5600-6000 rpm cruise.  Max rpm ever - with this set up is
6800 rpm which at 2500 MSL gave me an TAS of 202 MPH.

Gross weight is 1800 lbs, but average flight weight is 1650 lbs

Max climb rate (single occupant/half tanks) = 1800 fpm
Full tanks, full load (camping gear)        = 1350 fpm (gross)

Short wing, heavily loaded RV-6 is not the quickest climber for sure.

Cruise rpm is 5600 rpm at 8.5 gph, but may bump it  up to 6000 rpm if in a
bit of a hurry.

Static is 6000-6200 depending on OAT with 6000 being nominal

On way back from S & F, was burning 9.6 gph at 6200 rpm making 175 mph TAS
at 3500 MSL (in a hurry to get back home {:>) then bumped it up to 10 gph at
6500 MSL and achieved 6200 rpm but hit 181 MPH TAS.

I generally keep a log at 15-30 minute intervals recording rpm, fuel burn,
IAS, OAT, Altitude, Coolant and oil Temps.  Have about 8 years of data.

Over 11 years and 568 hours.
