Hi guys, so I just got my build running this weekend, its good except the idle is all over the place. Its a JMFab SMIM, with a BBK 75mm throttle body, and an inline ISC from a Nissan as in this article http://www.dsmtuners.com/threads/how-to-add-a-dsm-iac-to-any-aftermarket-throttle-body.448261/
Im logging and the ISC position is correct, and the car does have capability to idle, the ISC is just very behind and chases itself, if you rev it up and let it drop itll die, but if you let it gradually come down itll start counting up the ISC and catch itself. I have the throttle plate a little open to try and help, which I didnt want to do since it skews TPS readings. Im using the 3/8 hose thats on the BBK, and plumbing back in to the mani. Heres a clip, I had to trim the vid cause it died right at the end of this, you can hear it start to flash up. I was told the whistling is normal, its the throttle plate slightly open.
