The Thunder is our biggest, most advanced ECU yet.

The Thunder is optimised for high end applications requiring maximum performance, flexibility and tuning control. The Thunder has more inputs, more outputs and more features than any other Link ECU.
The Thunder isn’t just serious about performance, it’s obsessed.
