I am an electrical engineering student,writing a thesis on the topic "Fuzzy Logic in a Cruise Controlled Automobile".I am currently trying to model Yaris 2007 on MATLAB.In order, to model the engine system, I need the engine map ie a plot of Engine torque ,Engine Speed and Throttle opening.Can anyone please suggest how can to obtain it.ThankYou.

Something similar to the graph attached.

On the following thread there are plots from dyno runs with the torque vs RPM part. Some also plot the air/fuel vs. RPM, but unfortunately, none show the throttle position.

To get all of the data points you need, you're going to need a brake dyno and a few days to run multiple throttle/rpm hold points.

It might be easier to do the project based on a motorcycle, as their ECU maps are based on this tuning principal. You could call Dynojet or Yoshimura and they would more than likely provide you with a complete spreadsheet which plots throttle position vs. rpm vs. load vs. A/F ratio (if you told them it was for a class project....

Who knows, you might even be able to get an internship out of it!
