How to Shop for the Best In Line Module or Piggyback

How In-Line Performance Modules Work

  • An in-line performance module installs on or near your rides engine control unit (ECU), reads information from your engine’s sensors and sends a corrected signal to the ECU. You car’s computer then tells your fuel injectors and ignition coils to operate differently, which results in increased power or fuel economy
  • Very similar to an In-Line Module, a "piggyback" leaves your factory computer in stock form. They do however plug in-line with individual sensors, such as the mass airflow sensor (MAF), oxygen sensor (O2) and often into the factory computer itself
  • Because these modules work full-time, you’ll have to keep them attached to your ride while it’s running
  • In-line performance modules generally do not have screens and as a result are non-adjustable. But this isn’t necessarily a bad thing though because unlike other tuning methods, you can simply hook up the in-line module and hit the road
  • As a plus, an in-line module is usually mounted out of view so thieves won’t even know it’s there
