Or i guess just override ps_w directly, instead of having it integrate as a result of rl_w.

Pro tip, when you make baked mac n cheese, always use tillamook and also fill the pan with about half an inch of whole milk.
I have been making mac n cheese since before ddillinger knew what cheese was. That's a fact.

I'll just say this - one thing is theory, the other one is actually having a practical working solution.
The logic change isn't the issue, and anyone who understands ME7 can figure out how to do this in 5 minutes.
The issue is correct sampling and filtering, as any SD implementation samples the sensor crank/cylinder-sync and applies good jitter correction, to get a steady signal. This is where the majority of effort goes into.
After that it's just calibration. Mainly ESUK, due to the largely unknown fact that a MAP sensor signal is much slower than a MAF in transient conditions.
I have no interest on posting the solution, I've done enough. This time I'll just sit back with the popcorn. I've so far converted 2 other ECU generations to SD besides ME7 and faced all the challenges associated. ME7 is by far the easiest.

i`m using MAF input as 0-5 voltage input for doing something, but i have no MAF, i have no limp, i have only one MAP before throttle, i have working ESP. Since I cheat the ECU and use a mathematical model to calculate the air, instead of the actual sensor readings. And it`s only few bytes in code changes.

I still don't see the obsession to run these ECU's maf-less... it makes no sense what so ever.

if you want examples.. engine bay layout, direct intake to turbos with 2 highflowfilters, cold intake without Y, very high maxflow with good 780 idle rpm(big MAF sensitivity is crap) |

Still doesn't make any sense, as you can always do a blow through setup easily capable of 1000whp without issue.
There really is no good reason to run without a MAF what so ever.

MAF setups runs much better in daily driven cars as they adapts much better to different air temperature and humidity.

What is needed to convert from the standard configuration to blow-through in general? |

I haven't done one yet, but I doubt it would take more then properly calibrating the MAF tables. |

An HPX MAF and a love for perfectly linear fueling. |

What is the consensus with using an OEM ford (mustang and others) slot sensor instead of an HPX? clicky click |

Most oem sensors don't get good readings in blow through. Mainly if it has internal temp caps happening, it reports really low air flow because the extreme heat.

And what is wrong with such readings? IMHO it reads real values as MAF should compensate for air temperature internally (by hardware). Perhaps one should try to install such MAF post intercooler to have more meaningful airflow values.
