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

 

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

Subaru Impreza EJ20 TURBO WRX Z4 ECU * VERY RARE * on eBay, also, Subaru, Car Parts, Cars, Parts Vehicles (end time 20-Feb-09 11:39:17 GMT)

 

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.
