Why is Chrome better then Hondata

[GreenTeggy]

Too much to read! lol i think crome is cool how its free and stuff but i have a tuner who will tune my car for free and teach me while he's doing it ive watched him tune a couple cars and im starting to understand so ya i mean they are both good IMO its just budget really and if you like tuning yourself or not!

Cool. Or I can come to you 8)


and Aussie - I have heard the same about Crome. I personally have never experienced the issues you mentioned and I've tuned 3 or my own vehicles and at least 10 other vehicles with it. There is also the "learning curve" with any software and perhaps they didn't mess with it enough to get past the "learning curve" and become efficient with it which is why they had issues. I used to use Uberdata before Crome came out and it's a solid program, but has a lot of limitations. Never had any issues with Uberdata or Crome so I'll stick with the grassroots DIY route

Also, like I said, I haven't experienced those problems and after giving it some thought, I don't see why anyone would really. Think about it.....

The ECU doesn't know or care what is being used to tune it. It just looks up the tables and runs the engine based on the values within the tables. Whether you use Hondata or Uberdata or Crome or Neptune or do it manually with a hex editor, the result is the same. 300ms injector open time and 10deg advance is the same in the tables regardless of which program writes it in there. With that being said, I don't see how it can be more difficult to get a good idle and partial throttle with Crome than it would be with Hondata or anything else for that matter. You can make changes to the whole map, sections of the map, or individual cells just like Hondata so I don't see what the difficulty would be. Perhaps just like I said above that whoever is having those issues just isn't used to the program and therefore writes it off as "well the program has issues" when it's their lack of experience with the program causing the issues.

As for bugs, I've only had the program lock-up/crash on me once and that's only once which is great considering that I've had it opened and used in total for several hundred hours. For all I know it was the OS that had issues with it that one time too.

I understand why people like Hondata, but I don't understand why people don't like Crome. It is my preference and I will continue to encourage others to give it try.

That little chip controls everything with your a/f matrix, your ignition, etc. When they burn that they are burning their program on your ecu. It does a lot more then just "look at it". If it's programming code isn't working right your going to have problems. I'm not a software engineer but I will tell you that if your program is junk your car will run like junk.

On top of that the people tuning these cars having been tuning since before you and I were probably born. Don Flores of DFE in Jacksonville has been building Hondas and tuning them for ever, he used to race grand am, (and other shit I can't think of). Last time I was down there he was chucking all his chrome software out the door. He said the only thing he's tuning with is hondata. He'll still use standalones, like dtm and motec units but according to him the programs and support of chrome sucks.

You may have tuned a few cars but I think the problem is the other way around. I don't think you have enough experience with other programs to be able to tell the difference between a good unit and a bad one.

Partially true. For some of the "extra features" it is entirely based on the code of the program being used. Sure I could see some of that being "buggy" and I could see why people would complain about that. But as for TUNING, it does the same thing as any other tuning software. For the a/f and ign. tables, the tables are simply just plain old tables and the ECU really does nothing more than look up the closest appropriate cells and interpolates the values for the current conditions and then sends the appropriate signal to for ign. timing and the provides the appropriate ground for the injectors. You can verify this by opening the bin file in a hex editor and adjusting the # of columns visible until you start to see a pattern. The pattern is the a/f and ignition tables which would be written the same way regardless of what tuning software you're using. That's how the DIY community got started in the first place. By examining a stock bin file with a hex editor to start finding the patterns so you know what hex locations the tables are in and then figuring out what the values represent. From there you can figure out what the values need to be to produce the proper a/f and ign. timing. The new values are written in the exact same manner as the original ones so as far as the ECU knows, it's reading a stock bin file. It doesn't know any better and can't tell any difference except when it comes to the "extra features" but those are not even REQUIRED for tuning. They're nice but not required. So as for tuning, the program really should not make any difference except for the "extra features" and that is primarily up to preference and experience.

No doubt there are plenty of people with more tuning experience than I have, but I do have experience and that has to count for something. When I find something that works, I usually stick with it. I've tried the grassroots stuff for years and never personally had any issues. I've tuned 1 Hondata S200 and it was basically the same deal as the grassroots I'm used and had about the same outcome I would have expected from Crome, but the guy spent a lot more money on his engine management than the other cars I've tuned. Tuning is tuning. The goals are the same. The process is the same. The navigation and features of the software are different. Once you learn how to navigate the software and all the features it has, you're back to the same tuning that you would do with any program or even piggyback for that matter.
