Icon6 Starting air valve and IABS JDM h22a

Would it be benificial to swap over these two devices to my Jdm h22a? I have a tunable ecu running on it so I can activate IABs without an issue. If I do add in IABS what engagement point roughly should I use?

Vtec is set at 4688 as thats where it seemed to improve the overall powerband. I might go a bit lower to increase the overall power (smooth power band to more linear) rather than peak, which leads me to my next question though which is at what rpm I should be engaging my h22a vtec with stock everything except I/H/E?

I know I need a dyno tune to get the best answers, but as I'm trying to self tune I would like to know rough guidelines of whats approximately good for the average bolt-on jdm h22a.

Put it on a dyno. Tune the IABs yourself just like VTEC. Start with a low activation point, then a high activation point and see where the lines intersect. That's what I do. Seems like 4500 worked pretty well for me but I had Type-S cams on a 2.2 liter.

The starting air valve is pointless. Leave it off. IAB's will give you a bit more torque on the low end. Worth hooking up a wire IMO.

I noticed in my options in crome that I cant edit when my IABS engage. Its set over 7900 rpms. I want to set it to a different number but the map was generated off a set that didn't have IAB option. Is there anyway to edit the IAB?
