Topolino, Rocks-e & Ami Tuning — 8 → 14 HP & VMAX up to 80 km/h, without opening your ECU
Stage 1 boosts your small EV from 8 to 14 HP and up to 80 km/h — and we read & write the VCU3000 control unit via Bench, without opening it. The waterproof casing remains sealed, maintaining its IP protection — no risk of damaging your water-sensitive ECU. No one else can do this.
Casing Remains Sealed
Read & write via Bench, no boot mode opening. The waterproof casing remains sealed, maintaining its IP protection.
ECU Stays Intact
The ECU sits behind the bumper, exposed to water. Many destroy it when opening – we don't.
Ready-to-Use Control Unit
Pre-programmed like the original. Old out, new in, drive off. No one else offers this.
VCU3000 without CAN Loss
Normally, the ECU is dead after cloning. We are the only ones who clone it fully functional.
45 km/h is simply too little in everyday life
In today's traffic, you quickly become an obstacle with stock performance. Stage 1 makes your small EV more capable — and safer.
Too slow, too sluggish
- 45 km/h is too slow on 50/60/80 routes
- sluggish acceleration — you're stuck at the limiter
- traffic backs up behind you
- others overtake aggressively → less safety
More punch, higher top speed
With Stage 1 (14 HP, 44 Nm), you flow smoothly with traffic, pull strongly on inclines, and reach up to 80 km/h. No bouncing off the limiter, no tailgating — capable and relaxed.
For which vehicle?
Three models, one specialist. Choose your vehicle — either as an optimization of your own ECU or as a ready-to-install plug-and-play control unit (only available from us).

Stages & VMAX Variants
You decide how fast — and by what means. All prices transparent, freely selectable as a variant in the shop.
| Variant | Top Speed | Send your own ECU | Plug-and-play |
|---|---|---|---|
| VMAX Onlyjust remove restriction — no power increase | up to 53 km/h | 333.33 € | 888.88 € |
| Stage 1 + VMAXfull power (14 HP, 44 Nm) + top speed | up to 80 km/h | 699.99 € | 999.99 € |
| Stage 1 + capped VMAXfull power, fixed limit as desired | 50 / 55 / 60 / 65 km/h | 699.99 € | 999.99 € |
Send your own ECU: you send your control unit, we process it the same day and send it back. Plug-and-play: pre-programmed control unit from stock — old out, new in, done.
Two paths to the goal
We optimize your control unit
- Select vehicle + VMAX & order
- Send in control unit — we process the same day
- Optimized via Bench (without opening) returned — done
Ready-to-use plug-and-play control unit
- Order control unit (pre-programmed)
- Old control unit out, new one in
- Drive off — no sending in required
What Stage 1 really delivers
| Characteristic | Stock | 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 |
You'll notice the increased torque exactly where it counts: on inclines. Stock, the Topolino noticeably slows down on hills — with Stage 1, it pulls through cleanly instead of losing speed.
With the Topolino on the Nordschleife
We took a tuned Topolino to the legendary Nürburgring-Nordschleife — something no one has done before us. The video above shows how Stage 1 feels in real-world use. Honestly: With a cold battery, full VMAX is not yet available — you only get the full 80 km/h once it's warmed up.
How to reliably get 80 km/h
+75 % Power, more Punch
8 → 14 HP and 44 Nm make the car noticeably more capable in everyday driving: faster acceleration, safer flow in traffic, and strong pulling on inclines where stock performance declines.
Full VMAX at 15 °C+
Top speed is a matter of battery temperature — pure physics, not software. From approx. 15 °C battery temperature, full power is available. In cold conditions (e.g., around -5 °C), you start a bit more slowly (~60 km/h), and as soon as the battery reaches operating temperature, you get the full 80 km/h. Just warm it up briefly — then your vehicle delivers.
No Opening, No Drilling
We were the first to develop the Bench protocol for these control units: reading and rewriting on the closed casing, without opening it. Others drill a hole in the casing and then seal it with plastic — that's exactly where water gets in, and that's exactly what damages the already water-sensitive ECU. Not with us.
- safely utilize existing reserves
- cleanly raise torque and power limits
- precisely adjust VMAX to your use
- keep everything reversible — back to stock anytime
- no opening, no drilling on the casing
- no generic "internet files"
- no unsafe extreme values
- no technically nonsensical speed targets
Range, Consumption & Reliability
Practically Same Consumption
With normal driving, consumption remains practically the same — you even drive more relaxed because you're no longer constantly pushing to the limit. Those who continuously drive at full throttle will use more power and have less range — as with any EV.
Within Safe Limits
We stay within safe limits for the motor, controller, and battery. No extreme settings that overload components — resulting in factory-grade quality.
