Power Trip Part 6
Part VI - Tech - Power Trip - 559 HP 550 TQ
The classic FAST system was nothing to sneeze at, but the new XFI is still a big step forward in aftermarket ECUs. Sitting between XFI's billet enclosure is a processor that is four times faster than the old box and features the new C-COM WP Windows-based software for easy navigation. Going XFI means a built-in wideband O2 sensor and sequential or bank-to-bank operation, but that's only the beginning: its 104-pin harness enables tons of cool features. Quik-Tune allows the user to choose between four tunes at the flip of an external switch. Hook up a laptop and benefit from the data logging and diagnostic features (a new internal data logger will be available as an upgrade by the time you read this). There's boost control, fan/fuel pump control, TCC lockup, the choice of 1-5-bar MAP sensors, power adder controls, and a host of other tricks that are easy to access and play with, but will take weeks to fully appreciate! FAST also offers model-specific wiring harnesses to complement its XFI; since I already had a Casper's harness I'll need an ECU adapter for a plug-and-play connection. View Related Article
