Is it worth changing my standard UK ECU for the W6 from an import, will it perform any better??

Mines a 95 UK wagon with the TD04

Thanks in advance

 

No, a W6 is for a car with the TD05.

 

are you sure it's a td04 it should be a td05 fitted as standard to pre 96 uk model (saloon or wagon)
i have a 1994 uk wagon with a scott.t chip (polar performance) 1.1bar
before that i had a z4 ecu which worked well.

 

Your right it is a TD05...oh well will look out for a Z4 now then, It does feel a bit more responsive with the W6 although that could just be in my mind

What Impreza had the TD04 as standard then??

 

Wouldn't bother with a z4 have a look at PolarPerformance for their options (more expensive but worth it imo.

 

hmm you learn something new everyday..my 95 wrx wagon(import) is standard with a td04 turbo

 

map in a W6 is worse then the map in a UK. Both run the same boost but the UK has a better fuel/ignition map.

UK saloon and wagon is also a TD05 for all those that didn't know......
The only Pre96 with a TD04 is a WRX Wagon.....

 

Must stop assuming owners know what turbo they have
