So could the OMP simply not be able to pump against the higher compression that's a result of the higher boost; said differently the pressure at the OMP outlet is much higher than the OMP line pressure and the OMP is deadheading (infinite slip of oil in the pump with no forward flow)?

Yeah, it is for an AT N/A, 8000 RPM. So leave it at 12% and premix (I am premixing 7oz AmSoil Interceptor on 14gal fuel)
Here's what I know works: 1/ OMP maxed out at relevant load and rpm ................. ok up to around 10psi without any additional premix. 2/ Turn off omp and premix at 120:1 (100:1track) enables you to run safely at over 10psi |

I think what he means is that the oil volume being pumped is still not enough to properly lubricate at higher RPMs.
At around 14 psi while running E30 ..... you will bend your apex seals if you rely soley on the omp ...fact. If you aren't running any ethanol you might get away with it ....but then you might grenade the engine so ....................... |

I haven't tested to see if that combo (omp plus premix at 200:1) will make your engine last but it does seem logical.

Ok, thanks. Does the OMP max out at 60 steps? Or can I set it higher than 60?

60 is maximum setting ...any higher wont increase the flow and there is some risk you might drive rack off the pinion !

I guess this is the final nail in the coffin for the Cobb. Wouldn't recommend anybody purchases this software from a third party anymore.

Pretty prophetic for me to have gotten and saved a copy of every version for my Cobb device way back when.
ought to bump up the value when I sell it once the Adaptronic pcm is installed ;) |

This was the reply a customer got when he asked for help with his unit ...which had stopped working.
