Evening ECU Remap and Emissions Solution for Vauxhall Zafira in St Dennis

Another productive day working with our trade partners at Lockley Contracting in Mount Hawke, just outside Porthtowan. We regularly support independent garages across Cornwall, providing reliable ECU software solutions they can trust—and this job was a perfect example. Blocked DPF on a Vauxhall Corsa 1.3 Diesel Their customer’s Vauxhall Corsa 1.3 diesel had a blocked DPF, causing drivability issues and warning lights. As is often the case, the physical side of the work was handled by Tom and Ollie at Lockley Contracting, who then called Kernowsport in to take care of the software side of the DPF delete. Where appropriate, we also: Because the pricing is the same, most customers choose to take advantage of the performance and reliability benefits while we’re there. Clear, Simple Pricing – No Surprises One thing that sets Kernowsport apart is our straightforward ECU pricing structure. Unlike many tuning companies, we’re happy to: It’s a win-win: improved reliability, better driveability, and more value for the vehicle owner.

While that sounds daunting, the good

This last-minute call-out took us to Carharrack near Lanner to diagnose a 2010 Honda Accord 2.0 Diesel that wasn’t behaving as it should. The owner reported that the vehicle had previously been remapped and was now suffering clutch slip in the higher gears—a classic symptom that can point to either poor calibration or an underlying mechanical issue. ECU Bench Read for Accurate Diagnosis Normally, if a customer wants a remap adjustment or software update, we would work via the OBD port. However, to properly assess what had been done in the past, this Accord required a full ECU bench read. A bench read allows us to: We sent the file to our trusted calibration partners at Viezu for analysis. The Real Cause: Mechanical, Not Software Interestingly, the existing remap itself was not badly written. However, the data clearly showed that: This is an important point—and one we’re always upfront about at Kernowsport. Software cannot fix worn mechanical components; it can only mask the symptoms temporarily. A Sensible, Honest Solution Rather than pushing more power or attempting to hide the issue, we: This bought the owner valuable time—allowing them to continue using the car while planning and budgeting for a clutch

Today’s first job saw us working on this excellent Audi A5 2.0 TDI, originally from Mousehole, which was booked in at our partner garage Smiley Pistons for a DPF and EGR delete, along with a Stage 1 performance remap. Smiley Pistons certainly attract Audi owners, and over the past few months we’ve completed multiple Audi A5 remaps through their workshop—always a pleasure to work on such well-engineered cars. Low-Mileage Audi A5 in Excellent Condition This particular A5 was a low-mileage example, finished in classic black and in superb condition throughout. Vehicles like this are ideal candidates for software optimisation, especially when emissions-related issues start to appear. DPF faults are common on the Audi 2.0 TDI, particularly on vehicles that see short journeys or mixed driving. Rather than repeatedly repairing components, many owners choose a DPF and EGR software solution, paired with a performance upgrade to enhance drivability. Performance Gains & Safe ECU Programming As expected, the Audi responded very well to tuning, with the 2.0 TDI engine typically achieving around 200 BHP, depending on variant and factory output. Alongside improved power, owners also notice stronger mid-range torque and smoother power delivery. This A5 was completed via a secure OBD connection,
