Looking for a warranty-safe ECU remap in Auchterarder? Bob's Mechanical Repairs in Birnam writes supplier-verified maps for Auchterarder drivers — every tune is road-tested before you take the keys back. No generic downloads, no guesswork, just honest tuning with the safety nets in place.
Remapping done badly voids warranties. Done properly — supplier-verified, road-tested, fully reversible — it's far safer. We'll talk you through your exact warranty position before we touch anything.
Bob writes every map personally against supplier-verified base files. No generic downloads, no copy-and-paste tuning off a laptop in a layby. Your original file is backed up before anything is written, so the car can be returned to standard whenever you want. Every remapped car is road-tested on real roads before you get the keys back. We do not tune to a number on a screen — we tune so the car drives properly, pulls cleanly and does what you actually asked for, whether that is better economy on the Auchterarder commute or more pull when towing.
A remapped car is not a needier car, but it does deserve to be looked after properly. Keep to the service schedule, use a decent oil to the correct manufacturer spec, and change it on time rather than stretching the interval. We can service the car at the same time as the remap if it is due, which saves you a second trip. Oil and filter, air filter, fuel filter on diesels, brakes inspected, tyres and fluids checked — the usual thorough job, priced up front.
Before we write a single line of map, the car gets checked over. A remap magnifies whatever is already there, so if a Auchterarder car comes in with a partially blocked DPF, a sticking EGR valve, a tired turbo actuator or injectors that are already out of balance, we deal with that first or we do not proceed. The faults we see most on cars booked in for tuning are soot-loaded intakes on short-run diesels, boost leaks from perished hoses, and clutches that are already close to the end of their life. A stage one map adds torque, and torque finds a weak clutch quickly. We will tell you honestly if your car needs work before it needs tuning.
Auchterarder sits roughly 40 minutes from our Birnam workshop via the A9. We've remapped vans, tractors, family diesels and performance cars for customers across the Auchterarder, Aberuthven, Blackford and Dunning area.
"A remap is only as good as the engine underneath it. Fix the tired bits first, then tune — that order round saves people a fortune." — Bob
Give the engine time to warm through before you use the extra power, and let a turbo car idle for a few seconds before shutting it off after a hard run. If you run a diesel, get one longer, higher-speed run every couple of weeks so the particulate filter can regenerate properly — that matters more after a remap, not less. Keep an eye on the oil level between services. Modern turbo engines can use a little oil normally, and running one low is the fastest way to turn a cheap top-up into an expensive rebuild.
We are based in Birnam near Dunkeld (PH8 0DN), about 35 miles from Auchterarder — roughly 40 min in the car. We remap vehicles for customers right across Perthshire, including Aberuthven, Blackford, Dunning, Crieff, Gleneagles, and the wider Perthshire and Tayside area.
Bob has 32 years on the tools and writes every map himself against supplier-verified base files. We tune for what you actually want — better MPG on the daily commute, more pull when towing, or a sharper response for spirited driving on the A823 — and we road-test every car before you collect it.
Drop the car off, we run a pre-check (DPF, EGR, turbo, injectors all healthy), write your map, flash it, then take it out on real roads — not a real-world test route — to prove the changes feel right. Half a day, in and out.
