He said the one running 50 PSI is the one thats running fine. Stbd engine is the problem and pressure is within spec Go figure...

Ocean contender what was the problem??

50 psi on the rail on an OX66 is 15 PSI to high and will run pig rich.
50 PSI on the medium pressure rail on an HPDI would be good.
NOT on an OX66.
the ECU doesnt monitor rail pressure and does not know its 15 PSI above desighn limits but will turn on the injectors assuming pressure is still 35 PSI.
so we have way to much fuel,almost 50% more.
