Had my hawkeye sti in for a power run to see how it's running. the guy after the run said its achieving boost well but not holding and dropping off very quickly and also very rich. posting the graphs up if anyone can tell me if this is normal for this car or if there is a problem please.
thanks





mods on the car are prodrive sports cat,2nd de cat and panel filter

 

Has your car been mapped?

 

I haven't had it mapped. not sure if it had been before I brought it mate

 

11:1 dropping to 10:1 AFR. Stinking rich, lots more power to be had here.
Could do with a touch more boost too by the looks. 1.0 bar at redline dropping from 1.4?

 

that's what he said and suggested a new boost actuator may fix it

 

Well hawkeye never came with a sport cat so if it hasn't been mapped it will do ! Best advice is go see your local mapper get them to check it

Boost will tail off. 1.1 bar is std, so at 1.4 it would appear.to be mapped tailing to 1.0 sounds about right. It's a 2.5 remember!

 

mapping might also fix/help it if it's not yet been mapped. A diagnostic run to check the wastegate duty and increase if there is room (there definitely will be if its not been mapped before). The actuator replace is an easier way if your not handy with the laptop though just bolt it on and off you go.

fuelling as said definitely very rich and again can be adjusted in the map for you.

 

Ok thanks so it seems a remap is what is needed rather than a issue

 

It's a 2.5 engine not a 2.0l...
