For drivers in Comrie, Bob's Mechanical Repairs is your nearest dedicated ECU remapping workshop — just 33 miles away in Birnam, on the A9. ECU remapping — sometimes called chip tuning or engine tuning — modifies the software inside your vehicle's Engine Control Unit to release additional performance, sharpen throttle response and improve fuel economy. Every modern car, van and campervan leaves the factory with a deliberately conservative map designed to satisfy global emissions, fuel-quality and climate variations. Recalibrating that map for UK fuel and Comrie driving conditions safely unlocks the engine's real potential. Comrie sits on the A85 between Crieff and Lochearnhead — twisting Highland-edge roads with continuous elevation change. That's exactly the kind of driving where a quality remap pays back fastest — through smoother power delivery, stronger overtaking confidence, and measurable fuel savings. Every remap we carry out is custom-written for your specific engine variant — not a generic file pulled from a database. We take your vehicle's mileage, condition and any existing modifications into account, and we run a full health check before we touch the ECU. Comrie customers regularly tell us the difference is obvious from the first drive home.

Driving and remapping around Comrie
Comrie sits on the A85 between Crieff and Lochearnhead — twisting Highland-edge roads with continuous elevation change.
A correctly-calibrated remap addresses the exact pressure points that Comrie drivers experience day-to-day. On the A9 corridor through Perthshire, the difference is felt immediately — confident overtakes on the single-carriageway stretches, stronger pulling power on the climbs north of Pitlochry, and a noticeable drop in fuel consumption on the dual-carriageway runs.
For drivers who tow — caravans, trailers, plant, livestock — the torque uplift is genuinely transformative. Hills that were previously a third-gear crawl become manageable in fourth, and engine and gearbox stress drops accordingly.
Campervan and motorhome remapping for Comrie owners
Comrie is right in the heart of Scotland's best campervan touring country. If you own a VW Transporter, Fiat Ducato, Ford Transit Custom or Mercedes Sprinter conversion, ECU remapping will transform your touring experience.
Converted campervans carry far more weight than the original panel van was designed for — beds, kitchens, water tanks, awnings, leisure batteries and bike racks all add up. That extra mass forces the standard engine to work harder, especially on the Highland routes that drivers from Comrie tend to favour: the NC500, the A82 through Glencoe, the A9 to Inverness, or the A87 to Skye.
A campervan-specific remap raises low-end torque, sharpens throttle response and improves cruise efficiency in a single package. Most customers see typical power gains of 25–40%, torque gains of 30–50%, and fuel savings of 2–4 mpg on a touring trip. Over a fortnight in the Highlands that's a meaningful saving — and the driving experience is unrecognisable.
Why Comrie drivers use Bob's for a remap
Being only 33 miles from Comrie, we're effectively your local workshop. Drop the car in the morning and pick it up the same day. We've spent 32 years tuning vehicles that drive these exact roads — there's no theoretical guesswork, just experience.
Unlike mobile remappers operating from the back of a van, we work from a properly equipped workshop with diagnostic gear, a comfortable waiting area, and the expertise to handle anything that comes up. We've been in business in Birnam for over three decades — we're not going anywhere, and the warranty on your remap is backed by a real address.
Getting to the workshop from Comrie (33 miles, about 55 minutes)
From Comrie, head A85 east then A9. Continue toward Birnam — our garage is on Perth Road, immediately off the A9. The journey takes around 55 minutes and free parking is available at the workshop. Often called the 'Shaky Toun' for its mild earth tremors, Comrie is a popular base for touring Loch Earn and Glen Lednock.
Common questions
How far is Bob's Mechanical Repairs from Comrie? We're 33 miles from Comrie — approximately 55 minutes by car. Take the A85 east then A9 and our workshop is in Birnam, immediately off the A9.
How long does a remap take? Most OBD remaps complete in 1–2 hours. BDM tuning takes 3–4 hours. We recommend booking ahead so we can allocate dedicated time and complete the health check properly.
Will an ECU remap affect my insurance? You should declare any modification to your insurer, ECU remapping included. In our experience most mainstream insurers accept declared remaps with little or no premium increase.
What kind of fuel savings should Comrie drivers expect? Diesel vehicles typically see an 8–15% improvement in real-world economy, depending on driving style and the routes you cover most. On the rural roads around your area, the gains come mostly through smoother power delivery and less time spent in lower gears.
Is remapping safe for my engine? Yes, when carried out properly. We work strictly within safe parameters, run a full health check before remapping, and never push an engine beyond what it can sustain reliably. We've been doing this for decades — longevity matters.
Do you remap campervans and motorhomes? Absolutely. VW Transporter, Fiat Ducato, Ford Transit and Mercedes Sprinter conversions are some of the most common vehicles through the workshop. We calibrate specifically for loaded touring use.
