You put together stage, extras and hardware yourself. Today you only pay hardware and a 5 € deposit, the software once it is ready.

Configure nowWe adjust the maps in the original software of your DDE9 (MD1) ECU, depending on the engine e.g. boost, injection, ignition timing and limiters. The goal: noticeably stronger pull, sharper throttle and power delivery that suits the vehicle.
Every tune is based on the original software read from your vehicle and adjusted individually. No one-size-fits-all, no copy-paste from a database.
The original stock software can be restored at any time.

Unlock: send ECU in
Whether the ECU has to be sent in depends on its build date: up to 08/2019 the unlock runs straight over OBD2 and nothing leaves your garage. From 09/2019 onwards a bench or AutoTuner / FEMTO unlock is needed, so the unit comes out and comes to us. We quote the more demanding route here. If you know your build date or are unsure, just ask.
