FAQ

Q: What happens if the switch gets unplugged or a wire breaks?

A: The ECM will default to Tune 1. The switch works by changing electrical resistance; if the circuit is broken, the ECM senses maximum resistance and automatically reverts to first tune slot (usually base or stock) to ensure safe operation.

Q: Is the switch harness waterproof? What happens when I wash my engine bay?

A: Avoid blasting high-pressure water directly at the ECM connectors when washing the engine bay. Ensure factory rubber seals are fully seated to prevent moisture from causing voltage fluctuations between maps.

Q: Is there a delay when I click the switch to a different power level?

A: The change happens instantly, in less than a second. The moment you click the knob, the ECM immediately switches fuel and timing maps, though your turbo may take a brief moment to spool to the new target boost.
