Hi,

HP uses the left Y-axis and Torque uses the right Y-axis and they are auto scaled, so the curves will not cross at the same point as they would if they are using the same scale. 

I have had a few questions about this, and I might change them so they both use the left axis if this is more intuitive for people. 

That said, if you save the file, you get a .csv file which can be opened directly in Excel and you can do whatever with the data :-).

Cheers,
Jostein

i would love to be able to have this feature also where the end user " Myself" has the ability to switch either way, so BHp  and torque are both scaled on the same Y-axis

Horsepower and Torque always crossover at 5252 RPM if they are scaled on the same Y-axis scale numbers and in imperial units. I myself prefer this style of graph display purely the way it looks BUT is there any significant scientific advantages to it ? IMO no! Just looks

Is it possible to plot on the same  BHp/Torque  graph Air/Fuel ratio on the left hand side Y-axis ? If not maybe on the  "DO LIST! "

Error .made the last paragraph  should of read  " is it possible to plot on the same  BHp/Torque  graph Air/Fuel ratio on the RIGHT hand side Y-axis ? If not maybe on the  "DO LIST! "".

Good idea with the lambda and hp/torque together, that will be useful. I will check what needs to be done to make a generic solution where people can select where the different graphs go. It is a bit of work to make this, so it will not be very soon, as I am working on a number of other changes at the moment.
