Can someone please explain what the load block on my S3 is representing, how it is scaled etc?
Max load seems to be ~191%
Is 200% MAX load?
It seems to be on a 0 to 200 % scale.
"Load" in this case is largely calculated based in the MAF and reflects the volumetric efficiency -- i.e. how much air (and therefore also fuel) is going through your engine compared with how much is theoretically possible. If the engine were naturally aspirated, the Load value would top out at 100%. Without source code for your ECU's firmware, it's somewhat difficult to say where the calculation (inside the ECU) would top out.
Makes more sense now, so its basically showing that the turbo is making the engine give 91% more torque than if it was normally aspirated...
Think i got confused with load and torque there! DOh
