New iacv lowered by about 200rpm, but still idles at 1600-1800rpm warm. I can hear and feel the iacv port sucking air, so maybe it's wired up backwards or something. I reset the electromotive ecu to default settings and followed their initial setup / tuning guide and it responds very well off idle now, which I can live with.

Anyway, took it for the first Drive today. Needs some tuning, but not horrible for the first time.

Pretty sure my son was more excited than I was.
