Our first job after Christmas took us just down the road to St Erth near Hayle, making it a perfect local start to the year for Kernowsport. The vehicle was a cracking Ford Mondeo 2.0 ST, and it also marked the first outing of the year for our fully equipped VW Caddy mobile tuning van. A Proper Local Job for Kernowsport Being so close to home, this job was a great opportunity to put our on-board CTEK battery conditioner and KESS 3 ECU tuning system through their paces in real-world conditions. Stable voltage and professional tools are essential when reading and writing an ECU—and this setup ensures consistent, safe results every time. The owner, William, had paid top money for this Mondeo and it showed. The car was in excellent condition and a great example of a model we don’t see as often these days, with many drivers opting for newer or alternative brands. Stage 1 Performance Remap – Tailored, Not Generic We carried out a Stage 1 performance remap, using a custom-built file created specifically for this vehicle by our trusted calibration partners at Viezu. This isn’t an off-the-shelf tune—each map is tailored to the engine, ECU, and driving

Job number two today took us to Penponds near Camborne for a Volvo V60 diesel remap. While we’ve worked on plenty of Volvos over the years, this was our first V60, and it proved to be a great example of why careful, professional ECU work matters. The owner wanted improved drivability and efficiency, and trusted Kernowsport to carry out the remap properly. Why a Bench Read Was the Right Choice for This V60 On the Volvo V60, the ECU is positioned beneath the windscreen scuttle, meaning some trim needs to be removed to access it. While OBD tuning via the diagnostic port is often the quickest route, in this case we opted for a bench read. A bench read allows us to: It takes a little longer, but it’s the safest and most thorough approach, especially on vehicles where ECU access isn’t straightforward. A Relaxed Job With Great Results With the ECU safely read and written, the remap itself went smoothly. Volvo diesels respond well to tuning, delivering: Add in an hour of conversation about all things aviation, and before we knew it the job was complete and the V60 was back on the road. More Than Just a Remap

The first of three jobs today was this tidy BMW 320d, booked in for a Stage 1 performance remap. BMW diesels are always a pleasure to work on, offering excellent gains with minimal fuss when done correctly. This particular car had been stood for a while, and with the recent cold weather, the battery had gone flat—something that needs careful attention before any ECU work begins. Why Stable Voltage Is Critical During ECU Remapping When reading from or writing to an ECU, stable voltage is absolutely essential. Low or fluctuating voltage can cause interruptions, failed writes, or even ECU damage. At Kernowsport, we use a professional-grade battery conditioner specifically designed for ECU programming. These units aren’t cheap, but they are a vital part of doing the job properly and safely. It’s small details like this—often unseen—that separate a professional remap from a risky one. Quick BMW Remap, Big Gains Once the battery was fully stabilised, the remap itself was a straightforward and efficient process, as BMWs usually are. After the Stage 1 tune, this 320d was producing around 230bhp, delivering: Best of all, the owner was back on the road before the ASDA delivery arrived—which is always a win! Why

This Sunday job was an unexpected one—but also one of the most enjoyable we’ve done in a while. Back in the summer, Kernowsport attended a VW Transporter that had gone into limp mode on a holiday park in St Austell. We worked a little magic, got the van running properly again, and helped the customer make it home without further issues. Fast forward a few months, and that same customer got back in touch—this time with a rather bigger request. From Cornwall to Southampton… On a Sunday The customer had since bought a Ford Transit 2.2D tipper and wanted two things done before work on Monday morning: The catch?The vehicle was in Southampton. We explained that it was a fair distance from Hayle, Cornwall—and on a Sunday, no less—but the customer was adamant. He specifically wanted Kernowsport to do the job, based on his previous experience with us. After agreeing a price, we loaded up and headed off. Transit 2.2D – Tuned and Ready for Work The Ford Transit 2.2D is a solid platform for tuning, especially when used as a working tipper. A well-written remap delivers: Removing the speed limiter was the final touch—ensuring the van was fully ready
