Volkswagen Jetta IV remap: what changes

More power and torque without rewriting the ECU or swapping any parts. The GAN box only adjusts the engine sensor signals. Your manufacturer’s warranty is preserved: the ECU software is never changed, and the box can be removed at any time.

FAQs

Volkswagen Jetta IV remap: common questions

Which tuning box do I need for the Volkswagen Jetta IV?

Find your engine in the table above – each row shows the box and its price.

Is a tuning module the same as a Stage 1 remap?

Not quite. Stage 1 usually means an ECU remap without replacing any parts. The tuning module also works without replacing parts, but it does not change the ECU software: it adjusts the sensor signals, comes off in about a minute, and the OFF button in the app restores the factory settings.
