First Log on my MSM, take a look? yell at me?
Finally got the car up and running again after my fuse blowing and wideband calibration fiasco. I have a datalog for anyone that would like to look at it (basically the basemap from diyautotune logged on a car with the fm little enchilada)
I'm having trouble with my MAT/IAT reading being WAY off of what I'd expect, entered values for the sensor based on what DIY has listed and its still not right.
As frustrating as this has been thus far, the car starts and idles, and no longer dies coming to a stop after I calibrated the tps and entered the IAT/MAT sensor values in tunerstudio, so there's that accomplishment.

Key on, sensor plugged in, it reads -34*f without the car running... if I unplug the sensor it defaults to 70*f. I'm assuming I either have a bad sensor (car ran fine on the stock ecu with no codes), or my calibration is super wonky. Anyone care to share a difference in their calibration from the published values?

I think I have it sorted out now using some values I found in a previous thread. the biggest issue seemed to be that the bias valve resistor value was @ 5k, and should have been half of that @2490
Values I ended up using were as follows(originally posted by 18psi)
in F-ohms
8-199000
72-35600
180-3800
I'll add my new log for review as well
I'm fighting idle oscillation in closed loop, so I have it in open loop at the moment... but I definitely have some reading/work to do with regards to idle tuning in general
