I have searched this to death and still can?t get it to work. Under math parameters but after that I really don?t know what to do. Have about 9 options for map and the function on the tutorial won?t allow the map to stay as the sensor. Have no idea what I?m doing wrong or right. Any help?
i watched this video to set mine up skip to 8:25 in the video...hope this helps https://www.youtube.com/watch?v=X5k_QeWq2jk
Use this and it will log negative and positive.
([11.98]-[51.98])*(([11.98]<[51.98])+1+(([11.98]<[51.98])*.04))
Make sure you have the following PID's Logged:
11 Intake Manifold Absolute Pressure in psi
51 Barometric pressure in psi
I watched the video but when I do it on mine it returns a negative boost value. My MAP sensor is reading about 4.3 psi key on engine off so even if i do the "MAP(psi) -14.6" it comes back -3 psi boost.
The most it hit was -12 psi on one of the logs and that was at about 1/4 throttle merging onto the freeway.
It's a 2018 SRT Durango with a Whipple STG2 kit. Came with a replacement MAP sensor so I would really like to have the boost gauge to make sure i don't hurt anyt
