Hondata Thread - Honda CRZ Forum: Honda CR-Z Hybrid Car Forums

wicked1 · 12-13-2011, 10:40 AM

Who's got a Hondata on the way, and what other mods have you got on the engine? If they shipped on the 12th and some got the free next day shipping, we should have some toys tonight!
Hondata has the software w/ crz support up for download now.

I've got a couple of questions..
Does it matter if we have the recall flash done to our car yet? And can we have it flashed after hondata?

And 2nd question.
When removing the hondata and returning to stock, what program does it load to the car? Does it save a copy of my specific cars software, or does it have the stock software from Honda (and if so which, pre of post recall)?

If it's like any other handheld I've used it will return the stock program once flashed back. From what I understand, our car is already well tuned, and this won't add much for the money. Might be good with mods and a dyno, but standalone won't do much IMO. Also, if you ever have issues, the ECU will have a record of all your flashes and your local stealership will likely deny any warranty claims related to the powertrain once they run a diagnosis. They'll also charge you for that diagnosis.

Well, people say the same thing with warranty about adding an intake or exhaust or springs.. and all of those are done, in my case. (Well, intake and exhaust have been on order for over a month, and I just got notices form the vendors of MORE DELAYS).
And while I completely believe it's possible for Honda to detect the flash, Hondata claims they can not. Plus there are plenty of people who have been using hondata on other vehicles and claim they have no issues w/ warranty.. even w/out returning to stock (so, they get warranty work done w/ the modified flash).

About the gains from tuning, I'd expect most who get this also have other mods. Plus there is very mixed information about whether or not our cars automatically advance timing enough to take advantage of 93 octane, etc. If they do, then there will likely be few gains. If they don't and we can get a 93 octane tune, that will definitely give gains. (I personally think the car has more power and gets higher MPG w/ higher octane, but every time I mention that here on the forum, people tell me Im wasting my money and the car doesn't do anything to adjust to it)

Well, that's why I started the thread.. I'd like to hear what others think, and hopefully soon we'll have proof one way or the other. At least 3 people pre-ordered them.

Hondata missed there ship date and they should be shipping tommorrow so at this point its a waiting game for everyone. I had to cancel my tuning appointment and will have to set one up once I get it so I will post results once I get it.

With this product will there be a way to shut off the auto stop?

All I'm saying is that you can tell the ECU has been overwritten once you return to stock, which indicates a flash. That can be problematic. For example, if you have fuel pump failure, which I did once under a tuned car, they will likely deny you, which I was under that car's warranty. As far as gains, the car is already setup to take advantage of premium. Other Honda's do as well. The car occasionally attempts to up the tune via the knock sensors I believe, and with 93 octane you will see more power. This is a fact, and Honda acknowledges this.

Edit: found this statement on my old accord forum, and I know this applies to our car as well:

using higher octane in the 08 and newer accord(v6, not sure about the 4) will result in a few more hp. the 08 and newer computers are allowed to recognize and respond to higher octane fuel. they do this by advancing the timing which results in more hp. the downside is, that it takes about 150 miles of using the higher octane fuel to let the computer recognize the better fuel. there was a honda engineer that went on the record as saying this.

Note sure how it works in our car exactly (miles, etc..) but it works if you run premium.

Will the Hondata offer additional advantage over that? Maybe. Not sure if I want to shell out close to $700 (when all is said and done), for a couple horsepower in increment to what the engine can do on its own with premium. Plus, you'll still have to run premium on a decent tune anyway.

Thanks for the info. Personally, I think I notice more power after about 30 miles of using better fuel... but maybe it's just placebo. I really wish this stuff was published, as these are OUR cars! I can find and read the whitepapers with all the technical details of the software and hardware I use for just about everything else in life.
This is what's got me excited about the hondata is just being able to log this stuff and know for sure! Run a tank of regular and log it.. run a tank of premium and log it. Then we will know what the car is doing!

Also, I want to mention about the warranty, I'm not condoning using warranty if people break their cars by using aftermarket parts.. Just saying, I doubt they'd look for it, and hopefully they wouldn't use it as an excuse to get out of doing the work if it's not really related.

Agreed. The issue I had on my car that I flashed was that they went to the ECU to diagnose, and that's usually how they diagnose most issues. I think while they're there, they check for flashes as well. Dealerships usually get bulletins for this type of thing. For example, when Hondata comes out, dealerships will become aware and make checking the ECU for a flash a priority for diagnoses.

hi guys i have a question.

anyone know what gains i should expect on a stock cr-z with the flashpro? i only have a drop in k&n filter and thats it.

i dont want to fork out if there will be minimal to nothing in terms of gains.

i wish to keep my motor stock whilst i still have my warranty.

thanks in advance!

lldsandsll · 12-14-2011, 09:43 PM

just a few HP. can't squeeze much out of this car. fill up a tank of premium. you'll feel that just as much.
