im thinking about uberdata. but im confused on exactly everything i need. i want data logging so i can tune it, and see whats going on.

list of things i know (or think) i need:

uberdata software
laptop - what are the min. requirements for uberdata? im really only gona use the laptop for tuning
chips.................. --
rom burner............|-- where do i get these?
datalogging box?--

about the datalogging box. i know with hondata they give you one, but what about with uberdata? do i build my own or something?

also my ecu is a chipped/socketed p28 obd1. will any other modifications be necessary to the ecu? like for datalogging?

any info is appreciated, im trying to learn everything i can about all this stuff. anything im missing or need to know please add. i tried going to pgmfi.org, but it wont let me register for some reason. it says ive already registered, but when i try to get my password sent, it gives me an error saying it cant connect or some ****.

thanks

 

man, jsut do a search and youll find all that info. Also check out http://www.uberdata.org and http://www.pgmfi.org , and even http://www.homemadeturbo.com in the engine managment Forum... Its a great program, and it gets better every new update. Check out the uberdata forums for the latest version.

 

http://www.moates.net is where you'll find a rom burner

 

I never really looked into these free programs. How do they compare to hondata or aem and the top programs

 

like i said i tried pgmfi and uberdata.org (basically the same site) and i read them but they didnt answer all my questions and i tried to post, but it wouldnt let me log in for some reason. if you read my post rather then just reading the title and hitting reply "search search search" youd know this.

anyone else? a friend of mine refered me to http://www.xenocron.com/ anyone have any experience with them?

 

bump

 

xenocron has a good database of maps for different apps. Can be really useful sometimes. I bought my burner from moates.net, and use burn1 to burn the chips. Easy to use, pretty much self explanitory. Read up on uberdata to find out how to make basemaps and such. There are a few tricks you NEED/HAVE to know to get a working map started.

As for datalogging, it can be done using a special motorola phone usb data cable, and one end needs to be stripped and soldered to the ecu. Theres some good writeups in teh websites i mentioned above. It can also be done using a serial cable, but requires a board you can get at radioshack.

And pretty much any laptop with usb ports can datalog. I use a really shitty laptop at work to tune, but it has usb ports, so it works. I use the burn1 burner, which uses usb. Never had any problems with it. Im done for now, been drinking a little bit tonight.

 

lol, yea ive been drinking tonight too, lol. im a little confused on the whole serial/usb thing. the serial uses some chips and reisitors an capacitors and such, but why doesnt the usb? and why specifically this nokia cable? why not any usb cable?

and ive been looking at laptops and not many have serial ports it seems. i like the serial port idea, just cause it seems less "ghetto" and doesnt leave a wire hanging off your ecu.

basically what i want to do is be able to tune myself. read off the wideband and adjust as necessary. im also confused about the whole wideband/narrowband closed loop/open loop thing. liike when i make a chip do i still keep the o2 sensor or what? should i? or shouldnt i? im just confused on all that.

it seems theres all this information but no one breaks down everything. theres all this information on this, and all this on that, but nothing to bridge them all together. everyone says search but that doesnt help. i just need all the information in one continuous article or explination, lol.

 

Well, thats the info you just pick up from reading through forums over a long period of time, lol.

Right now, i am running open loop, which doesnt allow the ecu to make corrections that it sees nessesary from the 02 sensor. Its ussually a good idea when tuning so you can get a good map going without ecu correction. You can turn closed loop on or off in uberdata.

As for narowband/wideband, taht refers to the type of o2 senser. Mpost stock cars use a narrowband 02 sensor which just tells the ecu if your running between 14 and 15 to 1 a/f ration *i think*, dont qoute me on those values, but its close, adn there pretty much worthless for a turbo car tuning application. Thats why people get a wideband, little over 300 for most kits. I am using the plx m300. It reads from 10:1 all teh way up to 19:1. Its got a narrowband output so you can hook it up to your ecu and the ecu thinks its reading a narrowband o2. Also has a wideband output wire to hook up for datalogging. In boost tou want to tune for about 12:1, maybe a little richer for safety. Crusing you can be around 14.7-15.5 i noticed without it breaking up.

As for teh usb/seriel cables, usb seems to be less buggy, or easier to get working, but liek you said, not all laptops have serial. It requires a little board to be sodered in which cost about 10 bucks, plus the serial cable. The usb cables have a little board in them, but im not to sure exactly what it does to the signal. I know a regular usb cable will not work. Read in teh uber datalogging forums about that. Thats where the best info is.
