    Been having some issues with starting up in limp mode. I just dialed in my MAP and am in the midst of dialing in my MAFcal. I bought a new 3 BAR MAP but I'm waiting on the adapter to come in. This is KOEO right after driving for the first time after being trapped in the garage for almost a month.

    I should clarify, i have yet to install the map, just fyi. but I'm not entirely sure it's solely the MAP sensor's fault. I flashed a base 93OC MAP from VT, got some help from a friend on the MAFcal values, trying to dial them in but this is kinda in the way. I ended up having to customize my MAP values in the dashboard because the provided values on my CS 3.5 BAR MAP weren't reading correctly, not sure if that is a sign that it's faulty or what, maybe someone can give me a little insight on that. I'm curious if the load limits in the Tune Editor have anything to do with it as well though.

    You need to put your MAP sensor values in 3 places in the tune under the sensor calibration section, then flash the tune. You also need to set the parameters in the dashboard for it to log correctly. If any of your multipliers are too large and are not accepted by Tune Editor, you can enable unsafe values in the advanced settings, or you can divide the larger multiplier by the smaller and use the result as one multiplier and 1 as the other. This is basically like reducing a fraction. The multipliers define the slope of the MAP sensor.

    So since I posted this, I bought a 3 bar bosch map sensor. That brought my speed out of limp and got rid of my "vacuum leak" thank God. Currently working on calibrating my MAF.
