Ford JET Performance Tuner - Shopping Guide

From there they start to modify the spark advance and fuel curve in 500 RPM increments until they achieve the maximum torque and horsepower at the drive wheels in each rpm and load range, this allows turning under all types of various driving conditions and not just wide open throttle, a decisive advantage to the JET chip!

All the Data is stored on disk and transferred to the JET chip program so thorough track and street testing can be done under "real world driving conditions" to assure the Dyno results prove out on the road in decreased 0-60 mph times and quicker ¼ miles acceleration.

JET Performance tuning replaces stock computer tuning inside the vehicle computer to give maximum power and torque. The tuning can be delivered in the form of a chip that replaces the stock computer chip, a chip that piggy-backs the stock computer chip, a chip that plugs into the back of the stock computer, or a module that intercepts and modifies the signals from the stock computer with JET Performance Power Tuning. The type of computer in your vehicle dictates the type of device needed.

The tuning information is stored in the computer chip which controls all of the engine's characteristics like air/fuel ratio, spark advance, shift firmness, shift points, top speed, rev limit, and axle ratio. Sensors monitor many engine and transmission parameters like RPM, manifold air pressure, mass air flow, coolant temperature, intake air temperature and many more. These sensors send this information to the computer. The computer uses this information delivered from the sensors along with the information stored on the chip to deliver the optimum air/fuel ratio, spark timing, shift firmness, etc. for this set of operating conditions at that instant in time.

JET Performance can tune a vehicle for the conditions by using a dynamometer to measure horsepower output while altering the information stored on the chip.

This is how JET Performance maximizes your vehicle's power output!
