Fuel Cut Recovery r.p.m. (Injectors Switched Back On)

Question for Hondata

I got a daily driver ('fast street") with mild race cams + aircon. Car really likes to idle/return to idle at 1,200 rpm. Just like to know

What other parameters is the (fuel cut recovery rpm) is linked to in the s300 architecture

-vss,
-ect,
-iacv duty cycle,
-tps V,
-tps re-scale?
-fuel overrun tps/map
-ign idle control?

Did i miss anything? Seem to have a lot of touch points to other parameters, and subroutines/logic etc (if the fuel cut recovery rpm is changed)

What is the feasibility of exposing the fuel cut recovery rpm to the tuner? Any hardware issues? if there are then it's a strike-out I guess.

All in all, after thinking about it there would seem to be quite a lot of effort to expose the fuel cut recovery rpm to the tuner. would really appreciate your comments.

From a customer perspective, I would really like to see this implemented ASAP, as it has a high impact of the "total driving experience". Seeking more insight to manage my own expectations on this.

We've exposed all the tables the ECU uses to determine over-run cut-off.

Sorry, i was referring to the rpm the injectors are switched back-on. i have edited my previous post.

If i am not wrong the recovery rpm for switching back the injectors on is hard coded at 1,050 rpm.

Really appreciate some feedback on this.

Sorry, I see what you mean now.
I should be able to add the tables the ECU used into the next release.
