OK. Let's clarify just a little bit here... The hack is EASY to install, but it is not an easy hack. I spent a week writing it.

Some info:

06 Accord-
17.1 gal gas tank
205/60 R16 tire size, 25.68" diameter, 809.9 Revolutions per mile
215/50 R17 tire size, 25.46" diameter, 816 Revolutions per mile

06 TL-
17.1 gal gas tank
235/45 R17 tire size, 25.32" diameter, 821 Revolutions per mile

Don't know if this will help, but maybe...

I'm guesing that the tire size has to be known, in order to get the correct miles, kind of like when you put super swamper 33's on a toyota pickup, you need to recalibrate the computer for the correct tire size, or else your mph will be off... and also miles traveled will be off.

It works! Though I have the 3.30, I put in a patched 3.50 version and used CEBin to repack the BIN file.

When in the Trip Computer, the voice commands are dinked. For example "XM Channel 150" seems to ask for the current time and "XM Channel 45" turns off the "Reset with Refuel," or whatever that is. The quick workaround to this is to hit the AUDIO button, say the TL voice command you want and then hit the AUDIO button again to go back to the trip computer.

While I'm bummed the resolution is only 5 MPG, it's still pretty useful for seeing how fuel use is affected by various factors.

Thanks, AngryDad, for making this so easy!

Thank you all for your hard work and dedication. This is what makes this site so great. Let's keep it up.

Kennyc,
Just letting you and others know that I got the same exact "CRC check failed" warning during step 11 in Wyzard's instructions. It gave me 4 to 5 different warnings in a row. I kept clicking "ignore" and eventually got a message saying it was complete. I burned the 9 files to a cd and used it and works without any problems.

kennyc

hmmm.. I got that message b/c I was trying to patch my HMIManager.exe (3.40c) with AngryDad's patching program (for 3.50)

No more crc errors when I used his prog and patched a 3.50 HMIManager.exe

JCR69NYC

I want this!

Will someone please confirm for us....

The instant mileage "chart" shown above...it is indeed in 5 mph increments. But does the indicator jump in 5 mph increments? Or is it smooth and will display a value in between the numbers? Kind of like a clock with only numbers every 5 minutes. The clock will display minutes in between the numbers, you just have to figure out yourself that it's 7 minutes after because there are no hash marks in between the 5 and the 10...the clock doesn't wait 5 minutes then "jump" to the 10. Is this the same way? It doesn't jump between the 5 mpg scale does it?

kennyc

it does "jump" in 5 mph increments. In addition, I think the trip computer only polls the value once or twice /sec.

bluenoise

It does jump in 5 MPG increments, unfortunately. While I was driving home from work last night, it was jumping between 30, 35, 40, and 45 MPG while I had the cruise control set at 72 on level, straight freeway (San Mateo Bridge). Interestingly, it tended to hang out in the 35 and 40 slots the most. When I raised the CC setting to 75, it spent more time between 40 and 45 MPG. I guess the engine runs more efficiently at the slightly higher RPMs such that the additional wind resistance wasn't enough of a factor to hurt the mileage.

bluenoise

I wish it had 1 MPG resolution. In the diagnostics mode, there is a page showing trip computer raw information. There is an entry for speed (mm/sec) and an entry for fuel usage (ml/sec). Doing some simple math on those two values returns instantaneous mileage. It's too bad they chose to limit the resulting resolution for the TripComputer display.

brianp6621

You know, I hadn't really considered this possibility. However none of us really know unless Angry Dad can fill us in on exact what it does. Is it just activating something that is wholy contained within our BIN file and then my original statements are true, or is it telling it to call another file on the DVD which may be for the accord.

Angrydad?

brianp6621

And I have started to keep detailed records of the 2 trips computers. Basically every time I get into my car I record the current status of both trips and I am plotting the numbers in excel. I will will post more when I get more lengthy info.

mrodriques

IM me if you still need a place to host that file. I can set you up with an ftp link on my website if you still need it. No charge

CobraGuy

That makes this hack damn near worthless to me then. Too bad too because I was about to do it. Many thanks to AngryDad for all he did to write this, but it looks like the software engineers at Acura beat you out of what should have been an excellent result.

bluenoise

I was thinking the same thing until I installed it. While I wish the resolution was higher, the swings are wide enough to see how mileage is affected by various factors. It's also high enough to show me that I seem to get the best mileage when going 75 MPH. A little touch of gas drops the MPG from 35-45 to 10-20 MPG, which is more dramatic than I expected. Likewise, it's interesting to me how much time it spends north of 30 MPG.

Also, the resolution of the averages includes one decimal place. This is much higher resolution than the MID shows.

met152

angrydad,
If you don't mind my asking, what program are you using to determine where to edit/patch the .exe files?
I was looking at the blocks that you modified to enable the extra features, and my hex editor just showed nonsense at those locations.
How did you determine that you needed to modify the locations that you did? I'm not looking for each and everything you had to do, just a general overview of your process.

brianp6621

Watching the instaneous MPG meter is interesting but I am starting to question its accuracy. I have also noted that when cruising at 75ish with CC on, it stays around 35-45MPG. However even on them most cruise controlled long trips I have been able to manage (without stopping) I only ever seem to get about 31-32. I have a feeling it may be overestimating somehow.

The next time I know I will be on a long uninterrupted trip I will reset the trip meters and see what I get.

And I am still recording my Trip data, I am almost at the end of this tank. The DTE for the Navi and MID have crossed again (the MID started out lower and now it is higher than the Navi) I'm not sure we're going to be able to establish a relationship between the 2

brianp6621

Is there a part of the DIAG menu where you can tell how much gas the car thinkgs is remaining? This could help with my record of the trip meters. If there is, I will record this info also over the next gas tank.

kennyc

Thanks for the offer, I think we are good for now...

To recap, BrandonClaps is hosting one

http://home.usadatanet.net/bclaps/MPG.rar

and I now also have another one running as backup...

http://www.savefile.com/files/56150

and remember, use Angrydad's original patch for v3.50 disc and use the above links ONLY if you have v3.40c disc. They're patched and ready to go.

There is no way you can use an application to determine where to patch. You have to rely on your cerebrum. You can use any suitable disassembler to look at the code. I used IDA. As for the "nonsense", it is actually SH-4 code. I made quite a few changes in two locations: one that is responsible for displaying the menu, the other one is the place that calls different procedures depending on which menu item was selected.

P.S.: There is one bug that slipped through. Arrows in top-right corner of the info menu don't work as they should.

brianp6621

Not that I even noticed or really care, but will you be fixing that bug?

AngryDad

I have updated my trip computer code so it refreshes the screen faster. It helps. It also seems to be possible to change the resolution from 5 mph to 1 mph with medium coding efforts, but want to complete nag screen removal first.

/AngryDad

kennyc

My gf found something... if you change your color selection in page 3 of the setup menu, it changes the background color of the trip computer!

AngryDad

Not anytime soon. I have a whole lot of other stuff to take care of and it takes tremendous amounts of time.

/AngryDad

bluenoise

Awesome!

bluenoise

I think so. If you go through the DIAG menu all the way to the Trip Computer info, there are a couple of lines in the list of values showing remaining fuel (in liters, I think) and the number it's using to determine remaining fuel, or something like that. The first number moves all over the place, probably due to the sloshing of the fuel in the tank.

kennyc

Thanks! Is it ready for download? Original location?

brianp6621

remind me how to get there again?

bluenoise

Dang, I knew you were going to do that to me...

I'm trying to remember exactly, but it's something like DIAG>Functional Setup>Trip Computer

Basically, it's a long list of numbers that update about once per second and it shows things like speed in mm/sec, FUP (fuel usage) in mL/s, fuel remaining in liters, etc.

brianp6621

Oh ok, I thought it was more difficult than that, like hitting another button on one of the diag screens.

Kennedy

To adjust your "range" milage (what's displayed vs. how many actual miles left), you hold Menu for 5 seconds while in Diag mode

brianp6621

Umm, I can't get into the trip computer in the diag mode. It is greyed out. Blue, is it still active on yours?

Kennedy

iTrader: (2)

Ahh....
That's right. I haven't done the AngryDad patch yet. If you do the avlcat method and replace Himem and Diag.exe, you can then access the diag screen.

brianp6621

Crap, I was hoping to be able to use that screen to check exact fuel consumption.

Angrydad, I guess this is another slight side effect of your patch.

AngryDad

This is unrelated to the patch. TC item in diag menu is disabled on the TL.

There are two ways to get to TC in diag mode:

1. Patch diag.exe to enable this option
2. Use diag.exe from the bin where it is enabled.

/AngryDad

brianp6621

Weird, I SWEAR i've been in there before or at least somewhere in diag that showed fuel consumption and current speed in like mm/sec or something like that. I have searched on AZ and can't find the info again.

Also Bluenoise just confirmed and it is enabled on his but he had to do the whole edit and stuffing thing to get it to work on ver 3.3.

wyzard

Sweet. You are the man!

bluenoise

Here's what I'm currently running in my TL:

I have the 3.30 version of the navi disc. My car is reading BN2HH12C.BIN. Someone here graciously sent me their patched 3.50 version of HMIManager.exe, but I don't know how they patched it (whether or not they used AngryDad's patch). I had to pack it back into my BIN using CEbin, since it was several hundred bytes too big to use hacknavi, even with some creative hex editing. CEbin is able to deal with it being larger by updating the offsets, apparently.

After I installed it, I noticed the disclaimer screen is totally blank (free of text) and the "OK" button now says, "Go." The person that sent it to me seems to have done the disclaimer screen tweaks, too.

When I access the DIAG screens with the three-button salute, I can bring up the Trip Information screen that Brian mentions above. I don't see anything that is grayed out.

brianp6621

Huh... Anyone else out there with or without the hack able to get into the trip information screen in the DIAG menu?
