Hi, i write from Italy.....next time i will be an Impreza Sti Euro Owner.....i have some questions....

Sti Euro/Uk:
1) If i remove the 2 catalyst and pre-cat...the ECU run with Check-Engine!! how can i do for not run the Check-Engine??

2) When the ECU run with check-engine on, does only cut the solenoid for boost pressure or change also the Injection and advance?? (Recover) because on the Sti Uk ECU there is one Processor and i konw that for recover software is need two precessors on the Ecu, one for normal drive set and the other for check-engine drive set.

3) The Sti Euro/Uk with non catalyst how many bhp power increase??

Thanks in advance at your reply and sorry for may bad English!

Hi

the STI Euro Spec does not have the pre-cat anymore!

But I am pretty sure that you will get the CEL if removing the cats.
