wrx ecu upgrade
 

hey folks
can anyone tell me if i can upgrade my 94 wrx wagons ecu from a standard 3b to a wrx sti sb ecu and if there is anything else that needs to be changed at the same time.

cheers muchly

is it an auto or a manual?

manual

SB runs very lean and was mapped for a different turbo

:( ya'v shattered me dream man cheers. lmao:lol:

Well go for a Z4 or 6K ecu and a td05 (about £250ish perhaps) as far as i know you shouldn't have any problems but don't know if the engines are different in wagons to saloons.

Put your dream back togther again? :)

z4 it is then dude, cheers

OOOHHHHHH YES!!!!!!!!!!!!!

And turbo as well (not sure how a td04 reacts to a z4 ecu)

only 1 way to find out.
whats the worst that can happen, blown engine.
cool, 2.1 forged in it then and the misses wont question it lmao

Or you could try Products the chip will give you more power but on your standard turbo.

one on ebay

My problem with is 'Very rare' bwaahhhhhhh not likely and the price i paid £75 for mine 3 years ago but still worth a look on ebay though :)

true ha ha

im not sure that the z4 ecu and td04 mix is a good idea. the mixture will be wrong. asking for trouble. get a td05. there not that epensive. £100-£200 lst time i looked.
