Default my megasquirt seems to be failing me

This is a continuation of the thread in miata.net. I can't figure out a good way to post a .msq there so I uploaded it here.
my megasquirt seems to be failing me - MX-5 Miata Forum

In short the car won't start or run with this. The most recent change I made was to install an EBC and I added some tables in MS for that. Maybe I inadvertantly goofed something else up that I don't see.

The boost range has not been tuned yet, the car has yet to be driven with the turbo functional yet.

The other possibility is that there is something wrong with the hardware. I will be uploading datalogs as well.

You have changed your overboost protection to 69kPa. This means that the engine won't start, as starting is about 90-98kPa. If you check your log, there's no fuel pulsewidth anywhere, although you do get a solid RPM signal.

So increase your overboost protection to something a log higher than atmospheric (101kPa), say 170kPa (~10psi).
