Systems to monitor other data parameters of the operating vehicle are available, including pressures, temperatures, exhaust composition and lambda.   

Load algorithms are available for exponential vehicle aerodynamic drag simulations.  Perfect for our land speed racer clients.

February 20, 2004:  rare Ferrari 288 GTO comes to Speed Lab for a full day of careful fuel and spark mapping from our laptop computer.  Using pump gas and only 12-13 psi of boost pressure, the 2.8 liter twin turbo V8 now runs clean, with a broad torque curve making 414hp at the tire.  Ferrari rated this motor 400 hp at the flywheel.  What a great sound it made.  Photo by R.
