Vehicle Remapping

in partnership with Celtic Tuning.

McCreadie Vehicle Tuning.

Celtic Tuning Authorised Dealer.

We have teamed up with Celtic Tuning to offer engine performance and economy remapping for most cars and light commercial vehicles across Dumfries & Galloway and Southern Scotland.

Celtic Tuning are specialists in the development of engine management software where they have a specialist team of graduate level software developers. All software development is carried out in house using state of the art facilities which very few companies can rival, even internationally. Not all tuning is equal, a remap is not simply a remap, it is the end product of a lengthy development program. That is why we have chosen Celtic Tuning as our tuning partner.

Our remapping specialist at McCreadie of Newton Stewart also possesses an Honours degree in Computing and Electronic Engineering, so you can be assured your vehicle is in the best hands and all work is carried out to the highest standard.

What is an ECU Remap?

An ECU Remap is a re-flash of the engine management system which installs new software to change the operating parameters of the engine. An ECU Remap will alter parameters including throttle position, fuel duration, boost pressures, torque limiters, boost limiters, fuel pressure limiters, lambda correction and many more. Engine Tuning and ECU Remapping has become a huge industry over the last 15 years as modern engines have become fully electronic and therefore able to receive engine tuning via ECU Remapping.

What are the benefits of an ECU Remap?

An ECU Remap will provide a much improved drive, with a sharper throttle response, smoother power delivery and improved power for safer over-taking, as well as (for turbo diesels) better fuel economy. Overall, you’ll notice your car is a lot more enjoyable to drive.

Why choose a Celtic Tuning ECU Remap?

A Celtic Tuning ECU Remap provides performance increases that are not only both safe and reliable, but through their extensive development programs are also ahead of the competition in terms of power and performance. Celtic Tuning are genuine software developers who write and develop all software in house, no third party software and no copy paste like the majority of UK tuners.

We work on all makes of ECU’s including Bosch ECU Remap, Siemens ECU Remap, Visteon ECU Remap, Valeo ECU Remap, Delphi ECU Remap, Denso ECU Remap and Marelli ECU Remap to name just a few. As all Celtic Tuning software is developed in house it is possible to adapt the tuning software to suit your requirements.

We can provide all stages of Tuning from stage 1 upwards. All software is developed in house by Celtic Tuning using their two 4WD linked dynamometers. They test and log all engine parameters under all load conditions to ensure that boost pressures are constant, fuelling is within the correct tolerances, exhaust gas temperatures are not too high and that there is no additional soot on turbo diesels.

Our ECU Remaps are the product of extensive development and put us at the forefront of the tuning industry.
