Not sure which engine you have?

FAQs

Subaru Impreza I remap: common questions

Which tuning box do I need for the Subaru Impreza I?

Every engine in this generation is naturally aspirated, so it takes the GAN GA or GAN GA+. 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.
