so you never went in for the software update prior to your consumption testing?

_______________the chief mechanic is wrong. stock V-TEC is right around 5k (might be 5k on the nose actually) and the hondata reflash clearly states that it VTEC engagement is unchanged.
also as you stated before, the software update DOES reduce revhang, 03 and 05 ARE different... it may not eliminate it completely but it does reduce it somewhat (and yes it is differently noticeable in different gears).
____________________After getting my pistons replaced for oil consumption, I have noticed my rev hang to be about half as bad as it used to. I'm assuming they had to hook my car up to the mcvi reader while they reassembled my engine. Must have gotten the update. Regardless it does seem a little better. But I have a full race exhaust and it is really noticeable with a loud exhaust. Can't wait for flashpro to come out, hopefully it still fixes the rev hang like the reflash does.
___________________________________
Chief mechanic in Roseville, CA told me stock V-TECH kicks in at 3500rpm. (Reflashed V-TECH is higher) That would seem to suggest that keeping the engine under 3300/3400 is considerably better for MPG. Theoretically speaking, that is. Those in here seem to get mid-30's MPG at 60 - 70mph, which in 6th gear is what.... 3000 - 3500 RPM, right?

Does it normally take this long for FlashPro to come out? Has Hondata actually come out and said it's 'on the way'? Or is it possible (as some have speculated) that Hondata might forgo FlashPro on this engine because they're expecting it to be replaced shortly?
I don't believe this engine is going to be discontinued anytime shortly. There may be some hurdles to conquer but to my knowledge this engine will probably be around for awhile. Do you have any solid information that this engine is scheduled to be replaced shortly? A lot of people think that because of a few bad reviews (mainly for the interior and handling) that Honda is going to scrap the 9thgen and move right into a new design/style. This is a very small chance of happening. A few minor adjustments should be expected for the next model year (still a 9th gen with a k24z7 I will assume).
And I can't cite anything that flashpro is coming out, but it's pretty much a no brainer. I believe it took over a year or two for it to be available for the 8th gen.

8th car - first SI owners nov/dec 2005
8th hondata reflash - released June 2006
8th hondata flashpro - released May 2009
I pulled the 5k vtec quote from a press release, but I see that's wrong as well.
5,200-7k = ivtec indicator
Thanks, guys... you do great research. Those lights are pretty, for sure, but when they light up I generally have other things on my mind!8th car - first SI owners nov/dec 2005

Hondata has a reflash out right now that will help with the problem also increases red line and removes speed gov of 135. Hondata is also working on there flashpro (most everyone here is waiting for this) which is a multiple plug and play tuner that let's you do moreAnyone have ideas about what to do next, short of voiding my warranty?
A 7/12 build should have the ...50 update from the factory - You haven't experienced Rev Hang unless you've driven a ...30.I took my 4dr Si back to the dealership a week after I bought it this month and complained about rev hang. I was told by an assistant Mgr in service that it's "rev match" that I'm experiencing, and that it is built in to make shifting easier/better?! More on that in a minute. I brought a few pages of this thread witht the software info so they'd have all they need to update my 7/12 build with software updates. The guy looked through the Honda service system, never hooked up the car, told me there's no update from Honda for this issue, and that my problem is not a problem, it's built in on purpose and called "rev match."
I called Honda NA and they opened a case. They said there's no such thing as "rev match" in Honda terminology and that there is no update for my car. I explained that the car is horrible as a "driver's car" with this rev hang, and that I would return the car if I could. I told them that I was aware of software fixes outside Honda but did not want to risk voiding my warranty. Long story short, Honda NA does not care. In my view, if rev hang is intentional, it amounts to the chickification of the tranny, and I hate it, especially around town. Maybe If I had never driven those V8 and old 4cyl BMW sticks as a younster, I wouldn't know that rev hang does not belong there. But I did, and I do care. To know that there's a software tweak to get rid of it and that Honda won't apply it is beyond frustrating.
It seems that I am either being lied to by Honda at all levels, or some folks have received some sunshine pumping from Honda that "fixed" their rev hang. Anyone have ideas about what to do next, short of voiding my warranty?
