So my map setting was the 115kpa. I've read 1994's came stock with the 400kpa map. So that's my issue. I just want to make sure that is the correct map my car uses stock.

i don't see a kink anywhere, I have it coming off of the intake manifold around behind the head, through the driver side behind the radio and under the carpet behind my passenger seat. What settings did you use for your Baro and map?

It seems like you're genuinely lost and trying to learn so I'm not criticizing you, but want you to take a more methodical approach: You learn how everything works BEFORE you successfully start and tune the car. For example:
1) mspnp's do come with a 425kpa (IIRC) map sensor internally. Not the '94 model year of the car. So when you say the car has a map sensor, people don't understand what you're saying, cause it doesn't come with one.
2) For the last time: YOUR MSMPNP IS CLEARLY EITHER NOT SET UP WITH THE CORRECT FIRMWARE, OR THE MAP YOU'RE TRYING TO USE IS CORRUPTED, OR THE PROJECT IS CORRUPTED, OR ALL OF THE ABOVE. You don't seem to comprehend what I'm saying, but it's really simple: if everything is correct, your msq won't be set to run on maf based algorithm, and all of the other settings that you keep saying get "wiped out" will work and look right.
So start familiarizing yourself with megasquirt, tuner studio, and you'll learn that most (all?) of us set up the car to run on speed density, which means you'll need to switch your settings to that.
What I'd do: re-load the firmware for your unit. Hopefully you can still find it to download, and find the instructions to do it (not sure if that's still supported for original MSPNP's). Start a NEW project using the correct project settings. Start with a NEW map from scratch, you can look at/reference another base map for your car, but do not just put some random base map in unless you can verify that all the settings are correct, and it loads correctly, and it doesn't change any of the settings in the map when you load it into your unit. then make sure your MAP sensor is properly reading and set up. then calibrate tps. then make sure all your trigger settings and fueling/injector settings are set up correctly using DIYautotune's map as a reference (for your car specifically, again not just lumping it in blindly and hoping the car will start).
ONLY THEN are you ready to even try to start the car .
You're doing things backwards and just flooding the forum with a bunch of terribly vague questions and random issues. it's stupid. we can't help you until you take a methodical approach and help us understand true issues vs user error

Just go into the Engine Constants tab and change the map sensor from 115kpa to 250kpa (which is what it should be) in the drop down menu. See if the sensor then reads about 100kpa or less depending upon your altitude.

Ok, reality check time: I've been looking at the handful of threads you've made recently and they all confirm to me that you don't know the first thing about megasquirt and tuner studio, even in general let alone specific units and versions.

Great, and trust me the learning curve is steep, esp since you're dealing with an outdated unit that's not even supported yet and over a decade old, but in the end you'll have a lot more knowledge and quite a bit of it will help you understand newer units if you ever upgrade.

So this is interesting, I changed the setting and it did change my reading. But I'm the constants it did not do anything different. On different setting it read different. But I did that for ***** and giggles. The settings I need it on only reads 57. But on the highest setting (400) it read 83. Any ideas?

So i got it to "idle" BTW i have a V1.01 Megasquirt so i think it is the 115 KPA setting, Either way, i am also running my MAF for the time being. After changing speed density to MAF i was curious and tried to start it, and that is what you see. 12 AFR then my gauge went to 7.9 and flashing so i shut the car off and smelled gas. Should i try to tune and lean it out or order a IAT sensor and just wait? i also just picked up a ebay piping kit and a old intercooler for $60 so i have the piping when i want to install the sensor. I see my issue was in that, when people run speed density they do not have a maf. So the MAP has nothing to do with me ATM. I'm not sure if that's why it's reading wrong? If it is please let me know. I'm ordering the sensor now so I would rather want to know that it'll "work" when I start taking everything apart.

Alright, I'll try that later today. So am I correct in believing that I don't need a map signal for MAF fueling algorithm? I understand I need to correct it for speed density though. I need to order the IAT sensor, but I just don't want to install it then I'm fucked cause I can't get it to have a MAP signal.
