Can anyone confirm what the std ECU / turbo / IC etc should give in terms of AFR?

We have checked the car with a wideband and fuelling appears to be quite `sensible` e.g 13.2@3000rpm, 12.5@ 4000, 11.6@4500.......

I was under the impresion that the AFR would be far richer on the std ECU.

Given the above data, I can`t see a remap via PFC (at std boost anyway) giving a significant improvment in power. Anyone comment?

I would also assume if we add an AVC-R at say 1.2/1.3bar the std ECU would start overfuelling significantly?

Thanks.

 

Anyone?

 

Sounds about right for a standard car, if that's full load at 4500rpm.
But you may find it drops to mid to high 10's at the redline.
Which the PFC can set all of these a little leaner and still be on the safe side.
