More about Piggyback ECUs

A piggyback ECU works alongside the original ECU, modifying signals without replacing the entire engine management system. This can be useful for simple adjustments or when original functions need to be preserved.

Pay attention to which signals the piggyback can influence and whether that is sufficient for the desired modification. For larger turbo or swap projects, a standalone ECU is often a more logical choice.

Proper installation and neat wiring are just as important as the software itself for piggyback systems.
