**can i remap my own ecu using obd s/ware got from ebay**?
am looking for an answer for a friend. The question is: Can you chip a VW/Audi by plugging a laptop in and upgrading/changing the software? i.e. without requiring new actual hardware or chip.

Should i get a Mazda speed 3 07 instead of the subaru impreza wrx 07 (not STI)?


I have a laptop and also the correct cables/software for connecting to the car and changing service intervals / reading errors etc.

01' VW Jetta runs rough when the engines cold, HELP!?

In theory... yes.
What you need is :
1. Laptop/PC with USB or Serial COM port
2. VAG-COM software for diagnostic check
3. Flasher for reading original file from ECU and then uploading/overwriting with the modded file
4. Correct Cables (OBD2 and possibly KKL)
5. Software for modding the file e.g WinOls

Ford Focus 1.8 Ghia (2005/2006) - New Car ( Value to Buy ?)?


Problems...
If you bought from eBay, chancea are its the KWP2000 or something similar. These are cheap clones and have been known to mess up the ECU and possibly render it useless. When you write to the ECU, the car battery voltage needs to be constant... any drop or surge in the voltage could interrupt the writing process or worse still damage the ECU.

Where can i find a Mopar lightbar/bedrail??


Secondly, the modded files... most eBayers are selling the 30,000 odd ready tuned files. Don't touch them even with a barge pole! Remapping your ECU properly involves changing the values in the original maps/files. You can't just use pre-tuned ones. This can be done using software such as WinOls. If you don't know how to use it then companies such as Chipped UK will charge £50 to Mod the file for you. You just email it over to them.

I would recommend getting the car remapped from somebody who knows what they're doing. For your car they should charge between £200 -£250 max. (that dosnt include rolling road?Dyno). Just search eBay

MY 1990 ACURA LEGEND is stuck in first sometimes goes into secound could it be a drive line or silenode?

I own a shop, and do a lot of computer work on vehicles. You can in fact do this, but it will cause problems in the end, and you will void any warranty on the vehicle by messing with the program. I saw one where they flashed the computer, and changed the parameters on a VW. It then developed a shifting problem with the transmission that could not be resolved. Even the dealer can't fix the car until the owner buys a new computer. When the vehicle gets to a certain speed, it stops pulling the wheels like you had put the transmission in neutral. There is no problem with the transmission, but there is a problem with the computer. Unless the computer is put back in the factory mode, NO-ONE can resolve the issue. To answer your question; Yes you can do this, but you got to know how, and how to put it back like it was in the event the new parameters don't work out. Check the link at the bottom, this is a company that can help you out.
Glad to help out, Good Luck!

goto rosstech.com and see what they have for your model. The right software is called VAG-COM. Or if you want performance look in to either GIACX or APR Tuning.
