I have worked with a couple people to record data on various air cooled 911s in different areas of the country using a K type thermocouple and I am comfortable with that mounting area.
As an additional note, all of the Maxxecu models are splash proof with the exception of the Mini and the Race H20 which are considered water "proof". Given the CDI mount area, water migration is a non issue on the non water proofed models unless you plan on power washing the ECU or go for submersion.

Thanks for the answer, I have Megasquirt under my seat in a Targa and even though the Megasquirt seems to be a very reliable unit, it gives me a bit of pause since it seems more Heathkit than oem and a leaking Targa roof could put water on the floor.
It always seemed to me that in the full sun on a hot day, the interior is pretty darn hot too.
