Idle issues on startup
My car won't idle upon startup without feathering the throttle. Part of my setup may be to blame. Since I'm running a bov and not a bypass valve, the coffe can intake, I decided to use the inlet for the factory bypass valve on the 90 degree intake elbow for the IACV. I'm wondering if that is too close to the turbo for the IACV to function properly. I have the Robtune 550/TD05 with a FMIC. When I try to start it up, I have to use the throtte to even get it to start. Then once it is running, I still have to continue to feather the throttle to keep it running. If I left off the throttle, it will die but has caught itself a couple times and started to idle on its own.

Re: Idle issues on startup
I spoke too soon, I found one problem that was contributing. one of my silicone couplers had a rip in it. I replaced it, then started it up. It was rough starting it but now its idling on its own. Hopefully it stays that way.

Re: Idle issues on startup
It was still idling pretty rough, 500rpm, but it was idling which was an improvement. I adjusted the throttle stop screw a little and now it starts and idles perfect. Now I just need to tidy up a few things and take it on maiden voyage. Super stoked, hitting the launch control limiter, then hearing the blow off valve is music to my ears.

Re: Idle issues on startup
I would suspect the BOV is likely contributing to the poor idle, but it seems you've tweaked things a little to get it running ok.

Re: Idle issues on startup
I checked the blow off valve and I have the tightest spring in, it wasn't floating open or anything.
