Bazzaz Performance has developed an in-line Z-Fi Fuel Control Unit that precisely controls fuel delivery to optimize engine performance.

The Bazzaz Performance Z-Fi Fuel Control Unit is a plug and play unit that piggy-backs onto the stock ECU. Each Z-Fi Fuel Control Unit comes with an application specific harness that utilizes OEM connectors for simple installation and comes pre-programmed for either the stock exhaust or a slip-on. The Z-Fi Fuel Control Unit also features a USB interface with easy to use software allowing tuning modifications by the end user. The Z-Fi Fuel Control Unit is the first piggyback system on the market that can run up to 8 injectors independently. This translates into ease of tuning and significantly better performance. The Bazzaz Performance Z-Fi Fuel Control Unit can be run and / or tuned using the self mapping feature with the purchase of the optional Z-AFM kit.
