2012 Civic Si Rev Hang - Software Update

JonnyRotten said:
I cannot believe hearing about all the push back from all of the dealerships out there. To me if you have a concern about how your car is working the dealership should investigate it and do whatever they can to fix it. You also have the right to have the most up to date software on your car especially if Honda has created an update to rectify a known issue.
I would have a huge concern with any dealership who refuses to check into your request to have the software checked ESPECIALLY when everyone on this forum knows about the update from Honda. I would be calling Honda HO to escalate for sure.
I've already called Honda Canada to inquire about when the software is being released up here.
Don't just give up. :box:

The biggest issue is that Honda has not notified anyone that they have released this, usually a software update is release with a service bulletin which states the problem and what the solution to the problem is. This lets your dealerships, techs and customers know there is a problem and that they have a solution, it also allows the dealerships the authorization to book out warranty time on these affected vehicles. Since nothing of this sort has been released the dealerships neither know of an update nor do they know how to go about being able to have the work done for free for the customer under the warranty and to pay the tech his time to do the work. Also since nothing has been sen out from honda, anythig the dealership does would be the dealerships responsibility if another problem were see to arise from it, because Hondas question would be "well we never put out a bulletin or official update so why the heck were you updating these cars without our authorization?"If Honda would release a tsb on this update no one would have a problem getting the update installed.

A software update is now available for 2012 Honda Civic Si vehicles in the US. You need to take your vehicle to your nearest dealership to have the update done.

"Recommended Program Update X0A050"

The dealership will need to connect their MVCI tester to your car and will provide a trouble code reading "PGM-FI". The software update Program is supposed to greatly help/remove the rev hang.

"Rev Hang" is described as the throttle floating/hanging after you've put the clutch in/stopped pushing the gas, and the rpms do not drop.

At this point, the info has not spread around to all dealership staff. Most will have no clue what you are talking about until they hook your car up to the MVCI tester & see the trouble code first hand.

8/13/2012... Update: Despite having massive RevHang, today it was determined that my June built 2012 SI already has the "Recommended Program Update X0A050". So there is nothing Honda can do for me, or for others who already have this update. In other words, the XOA050 update is as good as it gets right now, and perhaps ever. If RevHang bothers you and you still need the XOA050 update, don't be in a hurry to get it. It fixes nothing, except perhaps the over-rev.

Meanwhile, check out the YouTube demonstration of the Hondata reflash. You'll be impressed.

Interestingly, the RevHang seems worse in the middle gears. Now why would that be? Well, there's no way to be sure... but we do know that Honda had its biggest problems (warranty wise) with the 3rd gear synchro. So I'm inclined to think that Honda intentionally built in the RevHang to save the tranny. I'm totally guessing here. But my next question is how the identical engine/tranny perform over in the TSX.

I'm not giving up here... not by any means.... I was just hoping for better news today. :lemonade:

Exactly my experience. It's annoying but I can live with it. And my dealership has all this documented so should I have problems in the future its covered. I recommend others have it noted as well by there dealerships.

Wow... I am so sorry to hear about your experience. You may be a perfect candidate for a Hondata reflash. But first let's get to the bottom of what Honda is doing - hopefully what happened to you is temporary. The ECU profile is determined by a wide variety of factors that are constantly in flux...so it may be a short term problem. Given that you have 4350 miles you probably bought the car early in 2012, right? So you might have had the original control module Honda used for this car, before the next two program changes to the ECU. Could you do us all a favor (??) -- post a video of your dashboard while going through the gears. Please and thank you!

I'll also post a video. It's very important that all of us irritated by RevHang (or now, the Honda solution) need to get on the same page.

YES, MY CAR WAS A JANUARY 2012 BUILT. KOOL, IF I HAVE THAT ORIGINAL CONTROL MODULE, THAT WAS FUN AND IT FEELS LIKE YOUR LEGS, ARMS AND YOUR SIX SENSE ARE ALL IN AN AGGRESSIVE MODE, LIKE THE OLD SCHOOL OF DRIVE BY WIRE.....YES, I WILL CREATE A VIDEO OF MY DASH (BUT, THIS WILL BE THE UPDATED VERSION ALREADY AND NOT THE ORIGINAL OUT OF THE FACTORY)......
 
BECAUSE OF THE UPDATE MY MPG WENT DOWN. I CANT GAIN MPG ON A SHORT AND LOW REVVING DRIVE. BUT, ON A LONG CONTINUES DRIVE AND MORE THAN 3000RPM OR MID-RANGE REVVING, I CAN GAIN MPG. NOW, IM AVERAGING 23 TO 23.5MPG BEFORE WAS 26 TO 27 MPG.....

Ouch... 23mpg hurts. Are you sure about that? i thought my 18.2 - 18.4 (first tank) was bad, although with too much vtech admittedly. No doubt the engine is tight, too...
I've been finding the TSX forums (same engine/tranny) talking about RevHang just as much as we do. They're using Flashpro. Will post results and proven calibrations when I have them.
 
just got back from the dealership and there was nothing they could do for me after connecting the mcvi. i guess i will just have to get the hondata.
 
So I took my si to the dealership today, physically watched the service manager connect the mcvi unit and ran it two different ways, and no update available....He also told me they had just updated everything straight from Honda the day before. My car was manufactured in May so we figured it might already have the latest updates....This sucks because I am still experiencing rev hang/overun....I guess I am s.o.l. unless Honda sends out a fix
 
yea man same thing here. i had the shop foreman and service manager drive the car and they both think its not driving correctly but they say that thats how honda designed it. im just gonna order my reflash tomorow.
 
I went to the dealership yesterday for my first oil change...told them i wanted the software update and they told me without a SB they wouldn't do anything. So pissed

I think it has something to do with how they bill their labor. Honda is afraid to issue a SB because they don't want to have to deal with affecting their car's rankings on something so trivial. Catch 22.

i got a bluetooth OBDII reader and am trying to use torque on my droid. is there a way for it to show me the firmware ECU #? the X0A05 or X0A03 thing?

It won't matter whether it's 03 or the latest, 05. The engine will still have tons of revhang. To some extent it does depend on the gear, and it's helped somewhat by having the A/C on full blast.... thereby creating additional load on the engine. In so doing, it helps reduce the rich point that caused Honda to buid in the revhang.

In any event, the reflash almost completely eliminates the revhang. My question is whether Hondata can produce a reflash using the stock rev limiter, rather than +200. That way maybe it won't be such a sticky warranty issue. Will get back to you when I have the answer.

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?

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.
