Just got Phearable stage 2 tuned - rev hang is still there... :-(

Exactly. And if it does somehow harm the cat, there was more likely a defect in the cat to begin with.

Again, otherwise Honda wouldn't be comfortable introducing the pops and bangs strategy in the first place.

Well, I'm sad to report that the overrev behavior did not change with the BOV install, as far as I can tell (I haven't driven a ton, but enough to have triggered the behavior a couple times already).

I still like the mod though, for the aforementioned reasons. Gonna keep it!

I'm sorry to read your report on the continuing Over-Rev behavior after BOV install.

A friend recently inquired (at my request) with his track buddy network and received a response from "?Honda People?" indicating their feeling that Tuners might not be addressing this problem, fearing problems with government EPA regulations. Their feeling was the over-rev and/or rev-hang was integral to Honda's emission strategy and could possibly result in legal action / fines if messed with.

I have no idea the quality of his source, nor the likelihood of it even being true. Especially surprising are the number of forum contributors who report no such issue with their cars. Mine is quite obvious - not something even a casual driver would miss in the right circumstances.

I would assume Cobb / Hondata, which are both tightly restricted ecosystems, have avoided tampering with this. Maybe Ktuner will eventually offer an 11th gen solution (my understanding is their environment for the 10th gen was much less controlled). You could also pursue an M1

Decided to keep the turbo and downpipe elbow blankets and installed them today. Used safety wire instead of the supplied safety springs as it's a much easier install that way. Used a proper safety wire pliers to twist and secure the wires.

So far, I've noticed an increase in low end torque especially from a stop light (since that would have previously introduced some heat soak).

Don't know if it's in my head, but lag feels reduced too.

Not in your head. Keeping exhaust warm keeps the gas moving. It's still nowhere near an NA or supercharged engine, but it does improve a lot. Especially as things heat soak and you're in the higher torque range.

 

[ashmostro]

Yeah, I know it's supposed to improve... But that's exactly why it could be psychosomatic hahaha

 

[ashmostro]

Drove a bunch more this weekend with the latest mods (thermal blankets and Turbosmart BOV). I gotta say, the responsiveness and overall power feel noticeably improved. Even my wife commented on it, unsolicited.

My ITS' driving feel is nearing ideal. I'm really happy with it.

Oh, and I did the fuse removal mod on the exhaust flap and there's really no drone. It sounds better this way to me! Other than not loving the triple tips, I don't have a desire for an aftermarket exhaust.

Custom tune can also change whatever/however you want with the flap in whatever drive mode as well. It's adjustable based on throttle load and rpm .

Add me to the list of people experiencing "rev overshoot". Like many others here i"ve owned several manuals, mostly Hondas, and have experienced rev hang to various degrees, but never anything like this rev overshoot. Took possession in 10/23.
