CB Tuning is a professional ECU file service built for tuning businesses across the UK. All master tools supported. Slave tool support for Autotuner, Kess and Flex. Average file return of just 15 minutes — reviewed by a human, not an automated system.
CB Tuning was built specifically for tuning businesses — from solo operators running a couple of remaps a week, to busy workshops looking for a reliable, expert file service they can count on daily. We support all experience levels and tool types.
Our files are developed in-house by our experienced team at CSC Motors in Glenrothes, Fife — calibrated and verified on our own 2WD braked rolling road. You get real results, not generic slave files purchased from a third-party server.
Every file is written in-house by our team using licensed WinOLS software. We don't resell generic files — every calibration is developed and verified against real-world data from our dyno sessions.
Our calibrations are developed on our in-house Dimsport 2WD braked rolling road — Fife's only one of its kind. Real measured gains, not estimates. You sell with confidence.
Every file is reviewed and calibrated by a human member of our team — not an automated system. Our average return time is around 15 minutes, with the portal staffed Monday to Friday 9am–10pm and Saturday 9am–5pm.
Competitive pricing designed for small and growing tuning businesses. Keep your margins healthy while delivering quality results your customers will return for.
You're not just buying files — you're getting the experience behind them. Our team is available via the portal and WhatsApp to support you through any technical queries throughout the process.
Want more than a base map? We offer fully custom Stage 1 tunes developed using live datalogging from your specific vehicle — available for a supplement on top of standard file pricing. Real data, real results.
Whether you're just getting started or looking to scale, we help with more than files. Website support, marketing advice, and setup guidance available for new network members.
We support all master tools — if you can read the ECU, we can write the file. Slave tool support is available specifically for Autotuner, Kess V3 and Flex. Named master tool support includes Blash and MPPS, with all other master hardware also accepted.
Autotuner is a professional ECU reading and writing tool widely used across the UK tuning industry. Available in both master and slave configurations, it supports a broad range of ECUs via OBD, bench, and boot mode, making it a versatile choice for tuners working across multiple makes and models.
Kess V3 is one of the most widely adopted slave tools in the UK remapping market, developed by Alientech. It enables safe, direct ECU communication via OBD on a huge range of vehicles without the need for bench connection, making it popular with mobile tuners and busy workshops alike.
Flex by Magic Motorsport is a powerful bench flashing tool designed for ECUs that can't be accessed via OBD. It's the tool of choice for harder-to-reach ECUs requiring direct bench or boot-mode connection — often used for deeper tuning work, TCU files, and vehicles where OBD access is restricted or unavailable.
Blash is a professional master ECU flashing tool designed for direct, transparent access to a vehicle's control unit software. As a master tool, it allows full read and write capability — giving the tuner complete visibility and control over the calibration data, without the restrictions of a slave system.
MPPS (Multi Purpose Pro Software) is a popular and widely used master flashing tool in the UK tuning community. It supports a wide range of Bosch, Siemens and other ECU types via OBD and direct connection, and is a common entry point for tuners moving from slave to master tool operation.
Running a master tool not listed above? No problem. CB Tuning supports all master tool users — if you can read the ECU and provide the original file, our team can write and return a professionally developed calibration for it.
Unlike many file services that operate standard 9–5 hours, our portal is staffed until 10pm Monday to Friday — specifically to support tuners who work evenings, run their business part-time, or tune as a hobby alongside their day job.
We also offer Saturday availability from 9am until 5pm, and Sunday support is available by prior arrangement — making us one of the most flexible file services in the UK.
CB Tuning is the file service arm of CSC Motors — a well-established ECU remapping and tuning centre based in Glenrothes, Fife, Scotland. With over 5 years of professional remapping experience, 3,000+ vehicles remapped, and Fife's only 2WD braked rolling road, our team has the real-world knowledge to back every calibration we produce.
When you order a file from CB Tuning, you're not dealing with a faceless file service or a reseller. You're dealing with a team of tuners who develop their own software, own their own dyno, and stand behind every calibration they produce.
"Stage 1 remap on my Volvo s60. Excellent gains and it's made the car a proper sleeper! Professional approach with communication and explanations on the process. Highly recommend!"
"Brilliant service and really good guys, used them twice now. Stage 1 remap and no issues at all, then again for a stage 2 and tcu tune. I'm very happy with the results. Totally transformed my car."
"Car was in for a swirlflap delete and stage one remap with gearbox, car now feels more like a 50d than a 40d and drives amazing. Couldn't fault the guys in anyway, they definitely know what they're doing."
