I have an older (maybe the oldest??? EDM930) - I know mine was installed when the unit first came out (there's some back and forth email printoffs from JPI with the then-owner). My previous owner was a military pilot and had them set the fuel unit up in pounds. Which I then get to do math every time I fly.

I'd like to change the fuel units to gallons (I know it's possible) and my OAT to C (now in F). I've followed the manual - did not work. I called JPI and they sent me some email instructions - also didn't work.

This is what they sent me:

  1. POWER UP THE UNIT.
  2. PRESS AND HOLD THE BUTTONS “STEP & LF”, UNTIL YOU SEE THE WORD “PROGRAM”, THEN YOU TAKE YOUR FINGERS OFF FROM THOSE 2 BUTTONS.
  3. KEEP TAPPING ON “NEXT” UNTIL YOU SEE “END?”.
  4. TAP THE BUTTON NAMED “FACTORY”, THEN YOU ARE IN THE FACTORY MODE NOW.
  5. TAP ON NEXT….UNTIL YOU SEE “FUEL UNITS: GAL”.
  6. TAP ON “EDIT”.
  7. TAP ON CHANGE UNTIL YOU SEE THE “UNITS” YOU WANT: GAL, KGS, LTR, LBS.
  8. TAP ON SAVE.
  9. TAP ON CLEAR…THEN THE UNIT WILL RESTART.
  10. GO BACK INTO FACTORY MODE AGAIN.
  11. TAP ON NEXT UNTIL YOU SEE “MAIN TANK SIZE = (A VALUE IN HERE).
  12. (TAP ON “PLUS” OR “MINUS” TO ENTER THE CORRECT VALUE).
  13. TAP ON SAVE….AND YOU WILL SEE “AUX TANK SIZE = (A VALUE IN HERE).
  14. (TAP ON “PLUS” OR “MINUS” TO ENTER THE CORRECT VALUE).
  15. TAP ON SAVE.
  16. TAP ON EXIT….THE UNIT WILL SAVE AND RESTART.
  17. NOW, CHECK YOUR FUEL TABLES TO SEE IF EVERYTHING IS CONVERTED CORRECTLY INTO LITER.

I never get to 4 as I do not see factory. Any suggestions? I am generally very tech savvy and can figure my way through any UI - but can't seem to get into the factory setting mode.

Hmm, mine might be the second oldest? Installed 2012… but I changed the temp units successfully, so it’s possible.  Try holding those two buttons before turning on the unit?  
I remember getting into that mode being harder than it seems it should be.  Maybe search for the install manual or look through any old documents you have for it?

Here, try these instructions to get to factory mode, i think they are very slightly different…

Thanks guys - and @Ragsf15e I'm jazzed to try that tonight. I suspect that step of a second double button push may be what I have been missing. Seems odd that there are so many "official" instructions on such a simple UI. I've tried my factory POH (no luck), the instructions from EDM (no luck), and a couple of other online manuals I've found.

Hopefully it works.  It’s been a while since i messed with it, but I think they played around with exactly how “Program” mode is entered so it depends on your software.  I had mine sent back and updated to once and it came back much different…
