Short answer: The VMAX de-restriction for the Opel Rocks-e increases the factory speed limit from 45 km/h to up to 80 km/h and boosts power from 8 to 14 HP (39 → 44 Nm). We optimize the VCU3000 control unit via bench — without opening the housing, IP protection is maintained. Starting from €333.33, plug-and-play from stock.

The Opel Rocks-e is factory limited to 45 km/h — this is software-based, not technically limited. The electric motor and control unit can do significantly more. With our optimization, you get exactly that out of it.
What Stage 1 specifically brings
| Key figure | Standard | Stage 1 | Plus |
|---|---|---|---|
| Power | 8 HP | 14 HP | +6 HP (+75 %) |
| Torque | 39 Nm | 44 Nm | +5 Nm |
| VMAX | 45 km/h | up to 80 km/h | +35 km/h |
The increased torque is particularly noticeable on inclines: the standard model falters uphill — Stage 1 pulls cleanly through. In urban traffic, you can keep up safely without holding up traffic behind you.
Without opening — the crucial difference
The VCU3000 control unit is located behind the bumper and is constantly exposed to splash water. Other providers drill a hole in the housing — this is exactly where water gets in, and exactly what destroys the ECU. We are the only provider worldwide who can read and write the VCU3000 via bench without opening the housing. The housing remains closed, and the IP protection is maintained.

Two ways to the goal
Send in your own ECU: Send in your control unit — we process it the same day via bench and send it back. Install, done.
Plug-and-play: Pre-programmed control unit from stock — old one out, new one in, drive off. No need to send it in. This offer is exclusively available from us.
Vehicle from 2026? No problem.
All others fail with the new 2026 data status. Our plug-and-play control unit still works — open VMAX and full power. The only ones worldwide.
Does this also apply to Topolino and Ami?
Yes — Fiat Topolino and Citroën Ami use the same VCU3000 control unit, the optimization is identical. All three vehicles at a glance →
Range & Reliability
With normal driving, consumption remains practically the same. We stay within safe limits for the motor, controller, and battery — reversible, no extreme values, results in factory quality.
