2017 Mustang Echoboost 4 Bar map sensor

[Stevie73]

Does anyone know the slope and offset values in inhg for a 4 bar omni map sensor. I have installed it and tried a few different values but nothing seems to work well. The car has been tuned professionally on a dyno. I am a new to tuning myself. The car has full bolt on's but i want to run a big turbo hence trying the 4bar map sensor. already running 24lb boost on stock turbo. Any help an advice would be much appreciated.

Slope 11.97 psi/V
Offset 0.506 psi

Hi, Car runs great after putting in the values you supplied, many thanks.
Only issue i have now is steering assist service and advance track service keep coming up....any ideas ?

No problem.

Don't know about the error messages though, probably best to scan codes on steering and ABS modules.
If you have a bluetooth OBD2 dongle, you can use Forscan.
Could be something as simple as a latent low voltage problem, or lost communications.

I drove it for maybe 20 miles switched it off and when i re started all seems to be good. no error messages and steering back to normal.
Thanks for your help.
