About South Coast Mapping
Hi, I’m John - and I run South Coast Mapping.
I’ve been working with cars for over 30 years, and honestly, I still love it as much now as I did when I first got my hands dirty under a bonnet. There’s something seriously satisfying about improving how a car drives — making it feel sharper, stronger, and just better all round.
Why I Started
I started South Coast Mapping because I wanted to offer a service that’s personal, honest, and genuinely focused on doing things properly. No rushed jobs, no upselling, no guessing — just proper ECU remapping and diagnostics that do exactly what they’re supposed to. Whether it’s unlocking more power, sorting out DPF or AdBlue issues, or fine-tuning the way your vehicle drives, I treat every car like it’s my own.
I’m based in Chichester and cover the whole South Coast. The best part? I come to you. Whether you’re at home or work, I’ll bring everything I need to get the job done there and then — usually within a couple of hours.
If you’re thinking about a remap or just want to know what’s possible with your car, feel free to get in touch or pop your reg into the checker on the homepage. I’ll let you know exactly what I can do — no pressure, no jargon.
