v1 sti
 

i have owned my wrx sti version 1 for a year now with out any hiccups. the car is all standard as far as im aware apart from a panel filter de-cat(not sure what the rest of the exhaust is). i bought it in this state and have just done the usual service and cam belt.
i have a rolling road graph in the folder of paper work i have from the car, would this suggest the the car has had some kind of mapping done? it reads max bhp 275. how can i check and would it be advisable to have it checked and mapped if nesessery . thanks

The ECU is located under the passengers feet. Its pretty straight forward to get to on these cars. Just a screwdriver for the clips, and a 10mm socket. Pull the cover off of the ECU and take a look in the lower right for a chip in a socket.

Alternatively, if you have a cable for it its even easier.

Most of the big name mappers will put a sticker on the cover of the ecu so you would know straight away by looking at it.

if its a v1 sti it will have a chip fitted from the factory, it will have a white sticker with faint green lines on it and computer type text. http://forums.jdmvip.com/Which_WRXST...preza-2079-t-2

Oh yeah thats right. I forgot the v1s came chipped. its still just a generic tune though, right?

It's defo v1 sti ill get out an have a look when I get a dry patch. What bhp should they be out the factory ?

yes generic

That kinda sucks... The V1 motors were hand built, right? I guess it would have been cool to have them hand tuned as well.

I guess that was the days before the "mapping hype"

I've managed to take a look at the ecu today and here it is. It looks slightly different to the one in the jdmvip link. http://i1061.photobucket.com/albums/...B16C83337C.jpg

Any thoughts wether this std or not. Thanks. Ben

std the aftermarket chip would be soldered in the large spare pin out area

Ok cheers mate. Would it be advisable to get it mapped as it does have a decat and a has panel filter.

Factory should be 250hp, V2 STi is 275 from factory

I've a print out from 2009 wich says 275 bhp was just curious weather it was on the rollers due to a fault, mapping, or just a power run.
