I've done lots of fooling with Uberdata, and I think hondata is worth the money.

My car (and friends' cars) ran like poo on uberdata. The car would barely maintan idle and would stall out all the time. This was after lots of tuning. Uberdata has that apparently un-removable hesitation at 600mbar that hondata used to have (removed in 3.5.5 of rom editor). I could not get rid of the hesitation without running the car in open loop. In fact, the car only ran OK in open loop. In closed loop on uberdata, the car seriously sucked to drive. From a long drive (say 10+ mins on the freeway), clutching in would make the car stall because the ecu couldn't catch the falling revs. This was with a target idle of 850rpm. The only fix was to up the target idle to 1000rpm which is garbage IMO. Running the StockGSR.bin with fueling corrected for the injectors (I have a wideband) the car experienced uneven torque delivery at partial throttle... i.e. the car did not feel "smooth" under light acceleration.

Uberdata does not have the ability to disable closed loop O2 based on MAP pressure. So you can technically be targeting 14.7:1 AFR @10psi going up a hill at 25% throttle if your turbo will do it. Hondata disables closed loop over a specified MAP pressure so once you hit boost you are running off the fuel maps alone.

In the version I was using (1.8) the save function does not work. Hitting 'save' on a map makes the application lock up. It is only possible to 'save-as'. Also, sometimes making changes in the Uberdata interface does not actually end up changing the saved file. I've set the rev limits, etc and saved the file out only to have the old rev limits written to the .bin file heh. All in all, Uberdata is really hokey... you really get your money's worth with Uberdata.

I know that with Hondata using the same saturated 650cc injectors I was able to use the Base B18C1, selected 24cc0->650cc and click the 'Modify fuel map for larger injectors' or whatever option and the car now runs 100% stock. No fueling changes out of boost have been necessary. I am running the stock fuel and ign maps out of boost and the car drives like stock No hesitations, no herky-jerky at light throttle like I had with the Uberdata (say, in a parking lot. Ugh it was impossible to drive on the uberdata).

I spent at least a week trying to get the car running with uberdata, so it's not like I didn't give it a chance. I tried Crome too and ran into some issues, mainly with an inability to maintain a decent idle.

I know that Uberdata and Hondata are based on the same Honda code... and I don't know why Hondata runs better than uberdata, but it does.

Sorry to go off topic, oh well.

 

why didn't you just tune with closed loop disabled? Also i've never had problems with my car stalling like you say even with closed loop enabled. In fact my car runs well with closed loop enabled and with closed loop turned on. With uber it is probably best to start out using 1.7 rather than 1.8. 1.8 is fairly experimental so far and has some bugs. 1.7 doesn't have those problems with saving like 1.8 does.

 

good info in here...

Thats one thing i noticed and one reason i orginally decided to go with the hondata.

run the motor how honda intended with expanded maps for boost.
Supposedly better idle and such as well. I assume a good tuner would solve all the problems when using the aem unit tho...</TD></TR></TABLE>

A guy i used to work with at honda had a 2.0 boosted gsr running the AEM EMS that couldnt idle for its life. (was only running 550 injectors too) Everytime he started the car, he had to rev it up and down for 2 or 3 mins, sometimes when he got out the car would still die.

 

honestly if your not going to go with a free editor like uberdata then please just get rid of hondata and get neptune unless you are going to be doing any tuning yourself. I've heard that you can get a tune+neptune setup on your car for $5-600. Isn't that right around the price of hondata?

I did tune in open loop. But I run the car closed loop for everyday driving... why waste gas? I had the same drivability problems with both 1.7 and 1.8. I moved to 1.8 to try to get rid of the issues and couldn't fix them.

 

What kind of burner would i need to make hondata chips? Do you need to continuously use new chips, or do you reburn the chip you have?

 

I am using this one:

You can burn the chips as many times as you want.

you can tune a little bit leaner than 14.7:1 for cruising and stuff. If its tuned well enough then it isn't going to really hurt your gas mileage.

 

I know I have tuned for 16:1 before with the AEM EMS at cruise and the car ran fine. Either way I like running closed loop. Uberdata cars run like poop closed loop (and still run like poop most of the time open loop). They only run nice in boost. I'll stick with my hondata

 

ehh mine runs perfectly fine..i'm not complaining.

That doesn't make sense, unless you're just a Hondata hater.
I can't make that judgment though as I don't pay enough attention to your posts.

But why are you saying to run either a free editor (uberdata) or Neptune?
Seems to me that for a little more than it would cost to go Neptune he could get AEM and have the option to tune himself down the line.
Or for the same price as it would cost him no for uberdata (remember he already has hondata) he can use his hondata. Which is every bit as good as uberdata, just costs more.

 

i kind of agree with the hondata hater comment.
I said this to dustin:
I want something i can go in, view all the specs, and edit easily that will run my car as stock like as possible. If somethine like that is possible to have.

The guy that has them aem said this to me:
The AEM has like 16 gpo outputs,all your base maps are included for any setup,onboard datalogging,no chips to burn all your different maps can be saved and loaded with out switching chips,you can run coil on plug setups,you can run 4 egt sensors right of the aem,traction control,its a true engine managment it not a hack to the factory ecu ,but don't get me wrong hondata is good but is limited to what you can do if you want to change something you have to burn a chip.AEM is not limited it can do any & everything you will ever want to do.

The only thing keeping hondata in my face is how clean its supposed to run and idle, just like a stock honda.

your right. I think for the price hondata sucks.

It sounds to me that he will be having somebody else tune his car. If so then why waste money with hondata? Sell it and use the money for neptune. It is 100x better and has iat correction so there is no need to really retune your car when the weather changes. If he is going to be doing some kind of hardcore tuning and wants to make changes himself all the time then aem is probably the best bet, but for a street car with only 350-400 hp i don't see why it would be necessary.

 

I agree with AEM not being needed for 350-400whp, however I'm one that likes to think ahead.
If he knows for certain that he will never want to tune his car (or won't have a problem spending 500+ again in the future for something new) then selling Hondata and going Neptune would be worth it. However, it seems like he has some sort of interest in eventually doing some tuning, so AEM is probably the better choice.

 

eventually i would love to be able to go out and tune a new setup all by myself. However, im somewhat new to FI and am not stupid enough to try it on my (insert high amount of money here) motor. Like i said, the only thing keeping me interested in the hondata is how smooth the cars operation is with it.


For the people running the AEM, how do your cars actually run? Im not talking about screaming down the track. If you had to drive your car from place to place, day to day how would it hold up? How does it idle at a red light? Things like that...

in that case i agree that aem is better. I think that if he wants to get started with tuning though uberdata is a great platform. I've never had a problem getting a car to idle right with it either.

 

I just ditched the shitdata and went to aem..man why didnt I do it sooner!!

 

&lt;---- will be picking up aem on wednesday

 

FYI..

my car idles like a dream on AEM after Jdogg helped me out..its alot to learn all at once but with the aem forum and people like Jdogg..its not that bad..

just remember the boost comp table and injector correction table and your off to a good start..

 

wheres that stuff at? I havent started learning about it yet....

 

IMO for a 350-400hp setup you will not need AEM. Also as far as hondata vs. uberdata...hondata is a rip. It is the same thing as uberdata, but costs a buttload of money. If you are willing to learn to do some stuff yourself then uberdata is the way to go. Also there is no need to burn chips anymore with uberdata. For $175 you can get an ostrich and tune on the fly and for datalogging all you need to do is solder in a usb cable into your ecu. Also if you are going to just let someone tune the car for you, but don't feel the need to make any changes yourself like you can with aem then neptune is the way to go. Supposedely it is about as powerful as the aem system, but way cheaper.

yeah what he said!

 

who the hell voted for hondata? lol

 

Well, look at what you can afford. Uberdata, even when given a chance, won't harm your car, worse case usually it'll run bad, or you need to weave your way around some bugs (and why try 1.8? 1.70 is stable, 1.8 hasn't any 'amazing' features over 1.70). Hondata you already have, it'd cost a big to upgrade and tune yourself, AEM EMS will run you much more. If the extra you put into the management prevents you from completing the car, why not give the free stuff a chance? Worst case you buy a $50 burner from ebay (which can be resold for the same) and a $15 chipping kit and semi-tune it w/o a wideband. Basicly w/uberdata you can't loose anything but some time. I would suggest a wideband with any self-tune option you go with, since butt dynos aren't very sensitive when it comes to a:f readings.

I'd rather have a complete car that I can add AEM to later than a car with AEM that I can't drive.

 

hey you need exhust and ic piping i can make it for you and im local sort to bmore 40 mins just let me know

 

Well i picked up the AEM EMS today. I got a sick deal on it. New in box aem ems with a new in box egt sensor + the guy printed the whole 300+ page ems directions out and put em in a binder. I gave me my hondata and $550 for everything
