Just thought I'd share another test log. 7.1# of boost to 27.7# in 700 rpm. The PS750 is certainly not slow to spool.
Nice. So are these soft limits for the tmap? So potentially the 3000 value would need to be increased?0x1C35C2, 2 bytes lsb, conversion: X*0.078125, PVDMX : Obere Druck Schwelle für Range Check

3000 HPA of absolute pressure is about 29ish psi of boost depending on the barometric pressure.
3000 hpa = 300 kpa = 3bar = 43.50~ psi absolute. - baro = 29ish psigNice. So are these soft limits for the tmap? So potentially the 3000 value would need to be increased?
Interesting that 500 is about 7.5psi, which would make sense for a lower limit if it's absolute pressure, as atmospheric would never conceivably be that low. But if it's absolute, then wouldn't 29-ish psi translate to a 15-ish psi boost limit? Or maybe they aren't both absolute?
Sorry, I'm probably mis-understanding something. Not the first time and definately won't be the last, lol.
Gotcha! I didn't realize you already subtracted atmospheric from the converted 3000 hPa value, and didn't convert it myself to see the 43.5 value - makes sense to me now Thanks!!3000 hpa = 300 kpa = 3bar = 43.50~ psi absolute. - baro = 29ish psig
500 hpa is 0.5 bar absolute so bellow anything you will meet on earth unless you drive on MT Everest.
Yes the 3000 value should be increased. "Obere Druck Schwelle für Range Check" translates to "Upper pressure threshold for range check".
I haven't looked at the routines thoroughly, as to what else it may affect, so increase with caution.
