Just wondering if I am running to rich at WOT? It reads 11.5 at wide open throttle. I'm at about 12.5 at idle and 14.0 at low rpm crusing. The car is a series 5 with a 6 port motor. Extended streetport, turbo exhaust sleeves, and a few other things. Right now I am running the stock ecu (N351) and Turbo secondary injectors for a bit more fuel at higher rpms. This happens even at low rpms, so I don't think the secondaries are the key if it is indeed to rich.
So is this indeed to rich for a NA motor?
Thanks,
Robert.

 

The stock map is pretty rich, and 550cc secondaries will just make it worse above 3800 RPM. This is a dyno from an S5 NA with just the stock ECU: http://www.pocketlogger.com/images/r...o_af_stock.jpg.

For this car, it even dipped into the 10s at high RPM.

 

YES! that looks very close to what I am seeing now. I'm not revving past 5K as I am still in breakin, however I have seen it get to 10.7 or so.
Do you think it would help to switch to stock secondaries?
Also I am using a FD fuel pump, stock regulator.

 

yeah put the stock injectors back in.

 

Did that this evening. Seems to be much better.
Running a bit better, and seems to have a bit more pep.
Thanks guys.
