That certainly could be, Steve. My EFISM does not check the length of the string - it checks for the FF termination byte that the EC2 apparently sends at the end of the engine data frame - regardless of number of characters in the string. In fact, I have found that the EC2 always send the FF termination string for any data sent over the serial port that is acknowledge by the EC2. For instance if you send the increment or decrement ignition advance, no FF is returned because there is no echo acknowledgement of those two commands but that is the only set I'm aware of that does not transmit the FF to signify end of string. However, I must say I have one of the old pre EM2 EC2 so may not have all the magic the newer one does.

It appeared as if that data was never transmitted by the updated EC2.

Apparently Tracy has put Battery voltage VBATL and VBATH in the positions that FFL and FFH used to occupy in the string and have moved FFL and FFH to the end of the string. Since I don't use either in my EFISM unit, I never noticed the change until Steve pointed it out. VBATL EQU 0x11A VBATH EQU 0x11B At the end of the string Tracy now has move the fuel flow factors FFL EQU 0x12D FFH EQU 0X12E Ed Anderson Rv-6A N494BW Rotary Powered Matthews, NC eanderson@carolina.rr.com http://www.andersonee.com http://www.dmack.net/mazda/index.html http://www.flyrotary.com/ http://members.cox.net/rogersda/rotary/configs.htm#N494BW http://www.rotaryaviation.com/Rotorhead%20Truth.htm -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of sboese Sent: Monday, July 20, 2009 3:17 PM To: Rotary motors in aircraft Subject: [FlyRotary] Re: Fuel Flow The FF data has been eliminated from my EC2's with recent updates so if you plan on keeping your EC2 updated, the investment in interpreting this data may not be very productive.

For those who may have done some work interfacing to the EC2's serial data, what does the FF (FFL/FFH - Bytes 0x2E & 0x2F) represent? Any insight to conversion formulas is appreciated.
