2G S90 throttle stop

[v8s_are_slow]

So just wondering if anyone ever adjust the throttle stop to help with idle. I have a new isc, fiav blocked off on a 74mm S90 and I know it might take a minute to get it warmed up. But it takes WAAAY too long and will still stall sometimes (auto) after blipping the throttle. The biss is all the way out. Just wondering who has ever had to adjust one to get the idle up because I can't think of anything else. Thanks!

That you have the BISS on that TB backed all the way out is strange. I assume from the description it has a block off plate for the FIAV but you have a FIAV and ISC attached to the bottom.
I forget what you're running for an ECU?
Have you checked that the ISC works and that it actually bypasses the butterfly?

Ecmlink. And yeah, it's working. Brand new and can hear it when the key is on as well. Just wasn't sure if I was the only one ever having to adjust it. Lol. Usually I hear of people with too high of idle.

What's ECMLink reporting for ISCSteps at idle and as it warms up?
Is your IPS simulated or actual and adjusted correctly?

At least for cold starts the FIAV normally does the bulk of the bypassing. The ISC opens pretty much the same amount for startup unless the engine is already at temp.

If you have to open up the butterfly a little to make it work better as long as you don't induce idle surge you do what you have to do once you've tried everything else.

Have to look at the logs. Can't remember. About to head out for new plugs though. And yeah, I'm sure this isn't a difficult situation to remedy. Just wasn't sure if anyone else was adjusting so was just curious more than anything.
