Came from a running car. There's been lots of talk about these on here: http://www.mkivsupra.net/vbb/showthread.php?331559-Anyone-tried-one-of-the-link-ECU-s/page10
Jamie's G2 sold for £500 here: http://www.mkivsupra.net/vbb/showthread.php?331476-Link-stand-alone-ecu&highlight=link
The G4 has even more features, drive by wire, knock control, fully sequential spark and injection etc.
There's a lot of support in the uk for these, and most reputable places will map them too. These are a really good alternative to the Syvecs for people not wanting to spend £3k+.
