Piggyback Fuel/Ignition Controllers


Piggyback Fuel/Ignition Controllers allow for tuning of the air/fuel ratio and work with the factory ECU. This is optimal for CAN-BUS equipped vehicles and allow features such as cruise control and climate control to be retained. When adding forced induction to factory normally-aspirated applications or full-blown race cars, the factory ECU systems generally do not allow enough control to maximize performance. In most situations, a fuel/ignition controller is sufficient for proper tuning. For the most complete solution for engine management please see standalone engine management systems.
