Engine Monitoring

Has anyone with a SR20 replaced the EGT/CHT with a same hole size engine monitoring system like a EDM 700 or Gem. Anybody able to utilize the fuel flow transducer that is already in to link to the Garmin 430s? At least I though I saw several references to the fact that the fuel flow transducer is already in and must drive the fuel flow guage instead of the old mechanical type guage I had on my Commander. Comments? Suggestions?

Obviously all of this is in light of the Arnav system and software not yet available and maybe not being available for my aircraft, scheduled for a February 15, 2001, delivery.
