Cant recommend ECUWorx and Martyn enough!
Extremely helpful and knowledgable. Martyn provided detailed instructions and guidance to any questions I had. Making the MSS60 programming a breeze with their proven cable and software. Martyn was kind enough to help me remotely, without any notice or appointment, when I got stuck on an unexpected programming issue. Amazing work and support.

Martyn is a rockstar, his customer service is amazing! It does not matter how long ago you have purchased his software license, he treats you and give you support like you got the license a day before!! I am happy to say that our company will continue to work with ECUWorx and their softwares, due to Martyn, he is a car enthusiast that cares about the car community and his customers. 🔥🔥🔥, we have performed many SMG conversions and DME/SMG performance tunes safely with him binary modification software 🥳

Bought a licence for the binary mod tool and removed the cold start from my e93 M3. All went perfect and now no more rev bouncing and occasional misfiring. I then purchased the AReeve remap and another success. My car is stock and mainly I was looking for a more responsive engine. For sure it’s much smoother now especially at slow speeds in low gears like in traffic. But when you open the taps you can feel it pulls much stronger. So an all around improvement. Well worth the money. A big thumbs up 👍

Amazing work from Martyn. Extremely helpful and knowledgeable. Recently converted my standard airbox to a CSL one and had my ECU mapped by Martyn. The map is night and day and the car feels great. Can’t recommend ECUWORX highly enough.

Martyn just my mapped my E46 M3 with the CSL clone software to go with my GSR box and the difference is night and day, I had a decent map before with my eventuri but the car is now a different animal!!! Pulls harder & smoother from lower down and a noticeable increase in power too.
Martyn turned the job round the same day and I had my ecu back the next day which is awesome service. Can’t rate him highly enough!!

Simple & cheap if you want to change a few things about your tune. Neibghours were not a fan of my straight piped e60 cold start in the mornings. MSS65 Binary Modification Tool + MSS6x Flasher and ECUWorx pre-flashed cable solved the issue in less than an hour. 🤙
