The Pendle method
Every Pendle file is calibrated in-house by Martin – the engine and the complete vehicle – and checked with a data log. Our calibrations are proven on our Maha dyno and on the road. This is how.
The Pendle method · 1 of 3
We start from the manufacturer’s own calibration and build on it. Every component stays inside its safe limits – nothing is overstrained.
The Pendle method · 2 of 3
Every map in an ECU works with the others. Torque, fuel, boost and timing are calibrated together as one – for the engine and the complete vehicle it drives – and judged on how it drives, not on a single figure.
Same engine, different drivetrain – a different calibration. A rear-wheel-drive van driving through a prop shaft and diff is given smoother, more progressive torque than the same engine driving the front wheels.
The Pendle method · 3 of 3
Calibrated across every pedal position and the full rev range, then road tested the way you drive: pulling out of a junction, foot down on the open road, braking and pulling away again. Smooth, linear power, effortless around town – the complete package.
Smooth power lasts. With no spikes in delivery, the gearbox, dual mass flywheel, drive shafts and engine mountings are looked after for a long working life.
Maha MSR 500 · Pendle HQ
Every job at Pendle HQ starts with a full health check and a baseline run on our four-wheel-drive Maha. Then it is calibrated, run again, data logged and driven on the road – and we don’t stop until it’s right.
Before and after every tune
Every vehicle is data logged on a full-throttle pull, before and after. Boost asked for against boost delivered, fuelling and rail pressure are read right through the rev range. Fuel is matched to the air, and the engine’s own safety systems never need to step in.
“It’s not about finding the limits – it’s working within the limits.” Martin
Turbo in control: boost within 0.05 bar of the request from 2,000 rpm. Real standard log, VW T5 2.0 TDI 102PS.
The data log report
Every vehicle tuned by Pendle Performance – at Pendle HQ or by one of our approved agents – now gets an in-depth data log report, before and after the tune. On the road, the Road Drive Report shows how the calibration really drives.
The question we’re asked most
“I don’t know until it’s on the dyno. Every vehicle differs – that’s why each one is individually calibrated.”
There’s one way to tune an engine: correctly and perfectly balanced.

In-house, by Martin
Martin has worked in WinOLS, the professional calibration software, for nearly 20 years. It opens up the whole of the ECU’s software, so every map is read, understood and calibrated for that engine – never a generic file, never a percentage added to a few maps.
Research and development · 1 of 3
Before we tune a new vehicle, we learn everything about it: the engine, the turbo, the injectors, the gearbox and the driveline – and which of them sets the limit.
Then the ECU. We identify it, work out how to read and write it, and study its whole strategy before a single map is changed.
Research and development · 2 of 3
Every step is proven before the next. The loop runs as many times as it takes.
Research and development · 3 of 3
A fully custom-tuned engine, with all of that research and development behind it.
Where it started
Martin began at sixteen, building and tuning engines for Peugeot Talbot – blueprinting, porting and boring heads by hand. As engines moved to electronics, he took that mechanical understanding into software. Thirty-eight years on, every Pendle calibration is built on his method.
Without our customers we wouldn’t have a business. Each and every engine gets maximum effort.
“This is what I enjoy. It’s not just work – it’s my hobby. I thrive off the technology side of tuning engines.”
