Help with idle on nismotronics sa sr20det

First post here to see how it goes. Have an s-13 withsr20det on speed density. Cannot get it to idle properly. Can someone get me started in a direction to figure this out. Ive checked for boost and vacuum leaks and find none. Running nismotronisc sa. Any help/guidence is appreciated.

Hi Carl, sorry but the nismotronic isn't an ECU that I've had any experience with so it could be a little tricky to help. I'd start by making sure that your AFR is sensible and stable, along with your ignition timing. It's also important to make sure your target idle speed is sensible - 900 rpm should be suitable unless you're running an aftermarket cam.
