were's the ecu located in the 03 sti's....and, if there was damange to it, would there be visual evedence, or is it just a black box??

I guess it would be in the same place as mine (MY01) under the passenger floor, just below the dash, lift the carpet back and you will see a silver panel, unscrew it and the ECU is in there.

It depends on damage, a smell test is always good, if it smells burnt, look for a burnt patch on the board, look for swollen Capacitors and so on and so forth. (This method applies for PC's so it wont be any different a way for any electrical device i guess)

Here is a pic of the ECU

If u were to look for your ecu, you should find it where the front passenger's foot well is located.

cheers guys

just had a look at it but didnt take it out of the covering....looks to nasa 4 me.....might go get some help from a pro or something.

if there is a problum with it would i have to get a new one....and if so should i get an ecutek or something...soz 4 all the questions new to the computer side of things.

As far as I know an ecutek is just a reflash of your standard ECU, if it is rooted you might need a whole new ECU. You can get a Link 2nd hand for about $800

could it be the problum of my boost at all??

Mate I am no mehanic, but write your problem up and somebody may be able to help you. If you want to know exactly what is wrong, take it to a specialist like RMS.

u have a problem with ur boost so u are checking the physical state of ur ecu?. hehe
