J-spec harness = junk. It's too short, and will be missing the wiper harness.

J-spec ECUs = junk unless chipped. Search "N374" and you'll see why.

Rtek will chip the N374. I specifically asked if it solved this problem. The answer was that at Pocketlogger, they were unaware of any 'problem' with 374 ECU's.

A little searching found that the 374 (unchipped) will usually work with an original S5 Turbo. It will almost NEVER work unchipped with an S5 N/A-Turbo conversion.

Bottom line if you can find a 370, it will always work.
