Safe removal of factory speed limiters for track use, exports, and specialist applications.
Contact us
Most modern vehicles come with a factory-set electronic speed limiter, typically set at 155 mph on German cars or lower on many other manufacturers. Speed limiter removal involves modifying the ECU software to remove or raise this electronic restriction.
This service is commonly requested by customers who use their vehicles on track days, are exporting vehicles to countries without speed restrictions, or are building performance cars where the standard limiter becomes restrictive. It's a straightforward software change that we carry out through the OBD port in most cases.
At Doyen Auto Services, we handle speed limiter removal as part of our ECU tuning services. It can be done on its own or combined with a Stage 1 or Stage 2 remap for maximum performance. We carry out this work at our Rutherglen workshop for customers across Glasgow.
