Form 337
I put a JPI Twin with Fuel Flow, OAT and TIT's in my FT337GP (a 1977 Reim's Turbo P model) under a Form 337 with local FAA approval. The FAA was OK, but of note, we left the existing EGT's in place.
Drop me an e-mail and I can scan the form 337 for you.
BTW, it is great to fly with. I run slightly lower alarm limits and it is great to see the alarm when the CHT's start to creep up even though the standard instrumentation is not showing increasing temps. It also helped point out the need for rework of some baffling in two areas that would not otherwise have been seen (two cyls running hotter than the rest).
I had hoped there was an alarm setting on the OAT for icing level temps, but that is not to be.
The Lean Find feature is also great and allows you to lean both quickly and accurately.
