6D ECU swap to Z4 ECU, plug and play?
 

Hello.
I am driving a LHD MY96 Impreza Turbo 555 Saloon.
I am living in Germay.
My ECU is a 6D (green Sticker).
Can i install a Z4 ECU to have a little more Power?
Is it plug and play?
Is it for same MAF, Injectors and so on?
What Fuel i have to drive with the Z4? 95 or 98 Octane?
Is there a 180kmh Speed-Limiter in the Z4??

Thanks for answers

z4 is for a td05,380cc injectors,green label MAF (not sure though if that means the same for import and Euro imprezas),98 RON is fine.

Limiter isn't on the ecu.

Think a couple of ecu pins may need to be swapped over though (crank and cam sensor i think).

You could always speak to Scott T at www.polarperformance.co.uk as he does do a generic map chip for early imprezas.Plenty of people have used them on here and have got good results but it is a generic map so results do vary.

dont know about my injector size, but yes its a TD05 and green MAF.

So it isnt plug and play??

If i'm correct then no it isn't sorry.

speak to the guy in the link i've posted and see if he knows.

i dont see why this wont work? lots of people have run a pre 96 jap wrx ecu in a pre 96 uk car. i dont think there is any difference between euro and uk.

UK/Aus/Euro ECU's V7, 7D and 6D - 11.47psi, dropping to 9.47psi at 6600rpm. With Fuel-cut @ 14.87psi

WRX ECU Z4 - 12.71psi, dropping to 11.78psi @ 6600rpm. Fuel-cut 15.65psi.

If it does work you must use super unleaded fuel and yes there is a speed limiter but not sure if it would apply in a uk as i think they use electronic speedo not mechanical.

Theres only one way to find out!

Yes my speedo is electrical.
