You may want to visit the APR or GIAC websites. They can tell you if there is a local shop that will do the work. If not, then they can help you remove your ECU and tell you where to send it to get the new chip. Good luck
Isnt the ECU like the computer? wont the car work without this, and also those webpages wont help me because im in Central america, not the states,so i doubt they can help me, and is this the only thing that can be done?
Yes the ECU is the car's computer. The car will not run without it. Inside the Engine Control Unit (ECU) is the Central Processing Unit (CPU) and Erasaeable Programable Read Only Memory (EPROM) or Programable Read Only Memory (PROM). The memory chips contain the engine management programs that the CPU uses to adjust the fuel / air mixture and spark when you step on the gas.
Most car manufactures including Audi adjust these stored programs to give the best overall fuel economy and reliability. There are aftermarket memory makers like GIAC and APR that have adjusted or re-mapped these programs to let the engine run with greater fuel consumption under hard driving (i.e. more horsepower) without changing any major engine components. However, most guys i know that do this also install a high flow exhaust and free flow air intake at the same time. This combination of upgrades allows more air / fuel to be burnt and expeled more quickly.
If there is no local shop that is authorized by APR or GIAC to do this kind of work they can send you instructions on how to remove the ECU by yourself and send it to the States for the chip. You may want to get a good idea of what all is involved with this process before you start. I wouldn't do this myself because of my lack of experience and the proper tools. Just my opinion.
I wouldnt personally touch one of those so called cheap chips as my friend bought one of ebay and it turned out to be a piece of wire with a resistor diode on it that he had to solder on to somewhere in the engine bay.
After all its only $19.99 -you get what you pay for.
My advice would be to search the net for a descent chip supplier and expect to pay about $2- 400 for it and get a garage to fit it to ecu for you.
