A safe map for driving to the track on pump fuel, and a stronger one for race fuel or water methanol once you are there.
You have since fitted new parts and need a software change, or want something like pops and bangs added, without another trip to us.
All three read your car, take a file tuned by us, and let you go back to standard yourself.
Perfect for beginners.

Well pleased with the increased performance of my Bentley GT. I didn't expect such an improvement. The service received by JFAutomotive was professional and polite, I would recommend them.
Great service would recommend to friends
Friendly and helpful service from knowledgeable professionals.
You plug the tool into your car's OBD port and read the original file. It comes to us, we tune that file for your exact car, and send it back for you to write to the car. You keep the original, so you can put the car back to standard at home, for example before warranty work.
Not quite. A full dyno session lets us measure the car while we tune it. A home tune still gives us full access to properly tune the ECU, so you get more power and better drivability than an off-the-shelf module.
Yes. For example a safe map for daily driving on pump fuel and a stronger one for track days on race fuel, or a map with and without water methanol injection.
Yes. The tools are in stock and sent by mail order worldwide, with remote support from us.
In the UK, normally 1 to 2 working days. We confirm the tool suits your car before we send it, so ask us first rather than ordering blind.
Not once it has been unboxed. That is why we check your car is supported and talk you through it before you buy. If you are unsure, ask us first.
Search the vehicle list on this page, or send us your registration and we will check it for you.
