**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.
I have a laptop and also the correct cables/software for connecting to the car and changing service intervals / reading errors etc.
Car is a '51' plate 130 bhp golfPD Diesel 1.9.
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
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.
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
