OBD Read & Write — No Workshop Needed
Locked ECU? We Unlock It Over OBD.
This is not a flash. RDSX does not read or write full ECU firmware. Instead, it uses a proprietary method we call Digital Block Reading & Writing — a special solution that targets only the specific calibration blocks needed for each modification.
New Renault vehicles with MD1CS006 and MD1CS016 ECUs ship with write protection active. RDSX unlocks them directly over OBD and performs Digital Block operations on the vehicle — no ECU removal, no bench, no shipping.
Connect your PassThru device to the OBD port, run RDSX, and the software handles the full unlock and block write sequence directly on the vehicle. No flash files are ever read, written, or transferred.
Once unlocked, only RDSX can read and write these ECUs. The unlock is bound to our software — no other flash tool will work on them.
There are no flash files provided or distributed. Every calibration value, block write sequence, and security procedure is embedded inside RDSX itself. You run the tool — the software does the rest.
Digital Block Write — Not a Flash
Targets only specific calibration blocks. No full ECU read or flash involved.
No Flash Files Distributed
All calibration data is built into RDSX. Nothing is shared or exported externally.
Works with Your Existing PassThru
PSA Interface, Scanmatik, and all J2534-compatible interfaces supported.

Emissions Systems Restriction Off
Tap to see details
The engine will start every time, will not block engine start because of AdBlue issue, and will not reduce power because of DPF and EGR. One single operation covers all three emissions subsystems at the ECU calibration level.
This tool cannot clear, fix, or remove dashboard warning lights, instrument-cluster error icons, or DTC fault codes.
If the vehicle has active DTCs or dashboard warnings, they will remain after the procedure. The tool only writes the requested modification — it does not perform diagnostic repairs. Any stored fault codes must be cleared separately with a standard diagnostic tool.
Start/Stop Off
Tap to see details
Permanently disables the automatic engine start/stop system at calibration level. Survives battery disconnects and ECU resets.
Speed Limiter Off
Tap to see details
Removes the factory-set top speed limitation from the ECU calibration. Ideal for commercial vehicles with restricted speed caps that limit highway driving.
Torque Monitoring
Tap to see details
Resets and recalibrates torque monitoring thresholds. Clears torque limitation flags caused by failed regeneration cycles or sensor drift.
MAP Recalibration
Tap to see details
Adjusts manifold absolute pressure sensor calibration tables. Corrects boost control behavior after turbo or intake modifications.
Cold Start Glow Plug
Tap to see details
Disables glow plug monitoring and fault detection. Prevents dashboard warnings and limp mode from faulty glow plug circuits without replacing hardware.
TVA Deactivation
Tap to see details
Deactivates the throttle valve actuator control in the intake system. Eliminates TVA-related fault codes and removes intake restriction for improved airflow.
Exhaust Flaps
Tap to see details
Disables exhaust flap valve control and monitoring. Prevents fault codes from stuck or removed exhaust flap actuators in the aftertreatment system.

Security Gateway (SGW) Notice
Vehicle Equipped with SGW? It Must Be Bypassed First.
All Renault, Dacia, Nissan, and Fiat vehicles from 2022 and newer may be equipped with a Security Gateway (SGW) module. The SGW blocks third-party diagnostic tools from writing to the ECU over OBD.
If your vehicle has an SGW, it must be unlocked or bypassed before RDSX can perform any Digital Block Write operation. Without SGW bypass, the ECU will reject all write commands from the OBD port.

What Our Users Say
Real feedback from technicians and workshop owners using RDSX
Based on 10 reviews
Had a Renault Master with permanent AdBlue fault and the engine wouldn't start. Dealer wanted to replace the whole SCR system for 3k+. Ran the Emissions Restriction Off in RDSX and it was done in maybe 15 minutes. Truck starts every time, no power loss from DPF or EGR. Saved the customer a lot of money.
Ran LaunchBoost on an Audi RS3 with MD1CS014. Launch control pull is savagely better — no more brake intervention cutting the party short. Customer grinned like a kid. Worth 10 tokens ten times over.
VW Golf R with MD1CS104 — LaunchBoost is the real deal. Throttle feels sharper off the line and the launch control actually delivers now. Unlocked 13/19/44 first as instructed, write went through clean on the PSA interface.
I was skeptical about the OBD unlock honestly. Other tools I tried couldn't write to the MD1CS016 at all. This one actually did it. Unlock + Emissions Restriction Off in one session. Only complaint is the token system could be explained better on the site.
We do a lot of Dacia Duster and Sandero in our shop. The Emissions Restriction Off on MD1CS006 is very reliable — done maybe 20+ cars with zero comebacks so far. Engine starts every time, no more power derate. Support answers fast when I had a question about the PSA interface setup.
Removed speed limiter on a Nissan NV300 for a customer who hauls on the autobahn. Works as described. I wish there was a way to set a custom limit instead of full removal, but for now it does the job fine.
Mercedes Sprinter with MRD1 ECU. AdBlue light was stuck on after a NOx sensor failure. RDSX cleared it properly, not just a DTC reset — the actual SCR logic is handled. This is the only tool I found that does MRD1 over OBD.
Customer hated the start/stop on his Trafic. Every other solution was a temporary disable that resets after battery disconnect. RDSX writes it permanently. Quick job, customer happy, I got paid. That's all I need.
Nissan Qashqai 1.5 dCi had torque limitation flagged after a regen issue. Dealer couldn't clear it. Torque Monitoring reset in RDSX sorted it in one pass — car drives normal again. Solid result for the price.
Bought tokens to do Emissions Restriction Off on a Fiat Ducato and Start/Stop Off on a Trafic in the same day. Both went through cleanly, no hand-holding needed. Better than sending ECUs away for bench work.
