for sale Link G4 Extreme ECU

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+.

Given these were twice this price when they were current, someone is going to get a bargain. Do the connectors, the map sensor and the comms cable come with it?

does this ECU have the ability to control torque between gear changes on a automatic?

No. Never found a need to to be honest. Done loads, most at least approching 500lbs/ft, never broke one, it's a myth IMHO. Use quality (and correct) fluid, change it regular (and the filter) and keep the fluid from over heating / burning.

Getting the NA valve body into TT boxes to run on the TT so that Dave P can work his magic and wide the box up to 11 seems to be the new want I get asked alot. For this reason I have begun work on a simple mappable NA 3 solenoid shift controller to work with Link so I can get rid of the stock ecu on Autos altogether.

Out of interest are these capable of running a twin fuel rail? With 12 injectors?

Comes with a 3 bar map sensor. Yes the connectors come with it, trying to find the comms cable, if it doesn't show up i will knock the price of a replacement off of the total.

Out of interest are these capable of running a twin fuel rail? With 12 injectors?

If you run them in batch then i guess so.

Out of interest are these capable of running a twin fuel rail? With 12 injectors?

yes, in grouped batch mode.
