New to this, Engine Dyno and tuning simulator

Hi, i am a Tuner and a Dynoshop owner, however this is mostly a dinosaur business and i want to make it available for newcomers and beginners to try out and learn the basics on how to tune an engine and how to run a dyno.

Sure thing real life is the best but not always the safest option.

I have decided to try and create something that is widely available for everyone and something that will be side project in the beginning, however i do not really know where to start.

the Requirements are the following:

Fuelmodel: Volumetric Efficiency

Engine Dyno, Hub Dyno, Chassi dyno,

Might build the engine management system model accordign to Open source projects.

Torque and Horsepower calculations.

I know it won’t be easy to recreate the internals but a rudimentary model for engine power can be used depending on a variety of variables.

i hope someone would love to help out with this.
