Is the UTEC a piggy-back computer or a stand alone engine management system?
The UTEC is a really a bit of both. It acts as a stand alone system in that it gives you complete control over ignition timing and boost. Fuel control, however, is piggy-backed off the factory ECU. The UTEC allows you to modify the MAF voltage, giving you the ability to control Air/Fuel ratios and to run larger than stock injectors. The factory ECU is also used to manage some of the more mundane functions that are necessary to keep a car drivable on a daily basis. Some examples are cold start, hot start, acceleration fuelling and closed loop fuel control. With future software upgrades available free from TurboXS, the UTEC will eventually allow complete control over fuelling allowing the user to eliminate the Mass Air Sensor. Does the UTEC run low impedance injectors? No. Do I have to start from scratch and do all the tuning myself? No. Like our Unichips, the UTEC comes pre-programmed for various sets of modifications like exhaust, turbo chargers, fuel system upgrades, etc. Although the
