Hi everybody, i've got some interesting information that I stumbled upon today. The basemap for the diypnppro for a 90-93 doesn't have barometric correction enabled by default and neither the product page nor the install page make mention to there even being onboard baro correction. But alas I found out that it is indeed onboard. Or at least I think it is and I am getting values for it.

Step 1: Make a new dashboard gauge with the input being barometric correction under calculations 1. See Figure 1
Step 2: Go to Basic / Load Settings and go to General Settings. Deselect the preset initial map reading and select two independent sensors. The input for this barometric sensor is analog input 3. THIS IS NOT MENTIONED ON THEIR WEBSITE OR INSTALL GUIDE WITH INPUTS AND OUTPUTS. Figure 2
Step 3: Go to Tools and calibrate Map / Baro.
Step 4:For the barometric sensor choose the MPX4115. It's default values for that sensor at 0 volts is 10.6 and the value at 5 volts was 121.7. Diy told me it was the exact same sensor as the map. When I tried using the same values for both I got a hard max kpa when I shouldn't have. MPX4115 seemed to yield the best results for me. Figure 3
Step 5: Start tuning your barometric correction curve. I've got some research to do on what a good base to start with is for that map.
