Now I get it

To get the atmospheric pressure you can read it before starting the engine or anytime when engine is not spinning (EOC), using engine's MAP sensor. Then remember its value to have a decent reading of the absolute pressure. It shouldn't vary from the absolute pressure much, unless you're traveling long distance or in mountains. But I'm sure that will be a good starting point for you, to get correct readings of the fuel pressure.

I had meant to have some sort of release candidate available for today, but the code I edited last night locked up for no discernable reason, no matter what combination of features I enabled. So, I'm going through the code again, this time with the MPGuino sitting right beside me so I can test the code as I remove features and insert #IFDEF statements.

Don't worry it's perfectly normal

I remember when I was changing my MPGuino code (based on metric "Canadian" version), and everything looked just fine on my tedt Guino, untill I havent uploaded the code to MPGuino mounted in the Berta. It's good to have many copies of the code and make a new one after any major change. But I'm sure you know that
Anyway it's a really great job and I'll be honered to be your beta tester
