Default Need Help ms3x

ok so, first post after lurking forever ( a good year or so since I've been interested in turbocharging my Miata) I've tried reading a lot and I mean a LOTand honestly I'm not afraid doing many things on my own. so I finally decided about a month ago to go with a ms3x and following brain's guide on trubokitty.com (though I put in all the components in the mainboard... it was fun lol and I really didn't have much to do anyway) and today I decided to make a custom intake with some of the intercooler piping I have and I modified to be able to connect the iac valve and a gm iat sensor. I loaded in the firmware and brain's base map and all I got was the engine turning over but stalling after a really short while. I took off the "stsign" fuse and put in a wideband O2 sensor (AEM 30-4110) ran the vacuum line from the FPR to the ms3x and boost gauge I have installed (though not boosting until I can get ms to run fine without boost) any help would be appreciated . this is what tunerstudio looks like right now on the cluster. not connected to the car though it's connected to a custom power supply for it though tps was the same when it was and I did disconnect it. planning to use a wells tps later

If/when someone more knowledgeable than me tries to help you, they'll more than likely ask for a copy of your .msq and a log of you trying to start the car. That's all the help I can offer, sadly. I hope you get it resolved.

Your post is incomprehensible. I'm not even sure what you're asking.

Are you saying the car cranks, starts, then dies? If so you need to tune it.

Recheck your settings. Base timing, all of your sensor settings, injector settings if you aren't stock.

If everything checks out then tune the car.

Everything is stock right now again. I checked the timing and it was off by 2 degrees I really hope this works! though would timing really affect it to that degree?
