I have fic 950cc And if it is the right injector scaling car will hardly run goes crazy rich like 10.9-11.00 at idle misses real bad and throws cel for to rich and injector 3 malfunction. Scaling at 812. I have checked injector clip they are on, also swapped injectors pte680cc, tried different injector resistor box to, different 02 sensor. But if I scale injectors at 1539 car will actually run and is Drive able with no miss... I am really stumped this..

Scaling is one factor do you have the right latency values?

 

get it properly tuned and you shouldn't have any issues. Also, this should be moved to the ecuflash section. You will get more response/help over there.

 

the tune isnt the issue.

 

As asked earlier do you have the correct "ballpark" latency values or have you found the real ones? When you switched to the PTE 650cc injectors what happened? Did you reset the trims before startup or are you trying to have it relearn based on the new values?

 

I went from Pte 680cc to fic 950cc and yes I changed the injector scaling as latency values.

 

Maybe the other 02 I tried was bad to? Is there a way to tell if o2 is bad through evoscan?

 

ok. what is your fuel pump? Are you on stock fpr?

 

Ended up being a boost leak between licp and turbo.
