OK, I'm an confused person. I reloaded megatune and then the initial MAP boro readings started to read correctly, so I started looking at the second sensor and realized I'd ordered a 4115 instead of a second 4250. Doh! So I changed the calibration values and now my real time display is dead on.

I've tried the default values, and the 10 & 260 values (about the same as the defaults) and it changes nothing. The MAP reading of 78 is correct, so I don't understand why the baro reading is so high even when I'm using "initial reading", it seems the sensor is being read correctly, but displayed ...

Sigh... Now I'm really confused. I added the second sensor but the readings I'm getting seem really off. At my elevation (7000FT ASL) I should see around 78kPa. In Megatune, I have a Baro reading at the top of the real time display window that reads 163 kPa, a baro reading in the corrections window ...

Thanks, sorry I missed that.

I see the option in the tuning setup for the second baro sensor, but have not been able to find any info on connections to add the second sensor (I'm using a V3). Is it undocumented, or did I miss something?? TIA
