have a sti v2 if i put a z4 ecu in
will it give me less ps 260 rather than 280

 

I'm sure a V2 with a Z4 should be 275ps. Isn't a Z4 standard on the V2? What have you got in it at the moment?

 

when i had alook i was not amussed to find a u8 but car goes well but only getting 0.8 bar could do with some more ha ha

Possiblyto better to get a boost controller and get what power you require from more boost, if you use thre right fuel and have the gauges for safety ( AFR, Knock ! ).

Best of all is a proper uprated ECU, like the link or Apexi PFC etc and get it all mapped in!
Safe smooth and powerfull!!

 

My V2 sti has a Z4 on it. It also has an eprom chip in it. Boost 1.1 and very quick. I'm sure you should be boosting at 13.8psi(nearly 1 bar). I'm a bit confused now about what a z4 is off

 

Z4 is off a 95WRx iirc 260ps... ?

U may have a U8 cover, but check that you havent got an eprom/chip inside.

So what should a v2 sti have?

 

Mine had a Z4 before the Apexi. used to get 1.1bar.
Not sure if this is the o/e ecu for this model though..

 

How much is it improved with the apexi and what's it boosting now

 

Car flies now. 1.7/1.5 bar peak depends on the weather 348bhp/330ft/lb

However the car was not slow with the Z4

 

thats nearly a hole bar more than you swine,
im going to get a decat downpipe first then the ecu im thinking
