Acert SDP ECM doesn't read oil pressure

Having this same issue with my 2008 389 with a tuned SDP. Did you ever fix this? if so how did you fix it

 

bump!! has anyone figured this out , my does exact same symptons except its random , both boost and oil pressure gauges go to zero along with a check engine light but it doesnt shut the engine down however I think it derates it a bit.???

 

Has anybody been able to resolve this issue?
Dealing with the same thing on a 09 KW W900 w/ c-13 acert.

 

Cgi absolute pressure sensor need to be installed... It works as atmospheric pressure and gives base reading for all pressure sensor.

 

Any fix found for this issue

 

any solution for the oil pressure issue. I replaced the CGI sensor and still had the problem
