The stack injection in the photo has a priority developed ECM that is a stand alone plug and play system. It comes with the harness and all you have to do is hook up the stock sensors from the Coyote. It controls the variable cam timing and takes sensor data from all of the stock sensors including "knock". After three days on a diagnostic engine dyno, a stock 5.0 L engine developed 437 hp at a 6500 rpm limit with an extend rpm range for peak torque to 5400 rpm peak torque of 375 ft lbs. No chassis dyno programming is required with this system.
