Ok so I want to change my KE to efi but there is a problem... Can I put ecu from Xr3 and than get a piggy back ( Power perfect smt6) or is it must to be ecu from fiesta turbo

 

Please forget about the piggy backs. Use one single management that can do the job.

 

So forget about the piggy back and go to get chip?? only?? Bu I wont to get about 2 programs... so I want to get piggy back And so Can I put this Ecu from xr3???

 

in other words use Fiesta Turbo ECU

 

In poland Fiesta ecu is imposible to get

 

Surely you can get one from the uk posted to poland ?

 

Use whatever programmable ecu you can get. Wouldn't really recommend an ecu from an original install.

 

Soo I can put ecu from xr3 then put to him chip and will be okey??

 

With programmable I mean properly programmable ones. Connect a laptop and change parameters kinda programmable, not "buy a chip" kind of. I would very much doubt that you'll find a suitable turbo chip for a XR3i type EEC-IV management.

 

soo after 4 months looking in Poland I can't find frst ecu... it is imposible... so I bought xr3 loom and ecu and I want to change map using piggy back... Or maybe somebody have ofac or ofab ecu and want to sell him to me to Poland

 

Buy an ECU off eBay, you can use the loom you bought with it.

 

Yes but I think about this, is it posibble to get a xr3 ecu and change map using piggy back... It is becouse that I bought xr3 ecu and Piggy back power perfect smtp7

 

Unfortunately as has already been said numerous times you need to move away from the piggy back idea and just get either a Fiesta Turbo ECU or some other FULLY programmable ECU.

 

Yes but there is new problem... most ebay seller sending only to UK Nobody want sending to poland

 

Just be patient i'm sure someone will send it poland for you

 

Soo If I have all escort xr3 loom in my car what ecu should I need to get him with out any modification with pin... OFAC or OFAB

 

OFAB is better, but it doesn't make any difference its very simple to change the loom for OFAB.
