Friends, Associates, Colleagues.. Lend them your clicks... 

The home of the best open source ECU in the world (although we may be biased).

UK based Rover V8 specialist and the first rusEFI tuning shop in the UK, these are the boys to engage for your rusEFI mapping needs or just some routine custom fabrication work on your TVR. 

Our more successful and more attractive counterparts in the USA. Specialising in the Miata but happy to take on any rusEFI powered challenge, this is the place to go for your Miata PNP needs in the USA.

Always somehow able to accommodate our unusual requests, DY specialise in Japanese engines but can do awesome work on anything you can throw at them.
