project_850 Posted April 14, 2010 Report Share Posted April 14, 2010 Just curious to see what everyone's running. Link to comment Share on other sites More sharing options...
98 s70 t5m Posted April 14, 2010 Report Share Posted April 14, 2010 Mine seems to start at 12, settle at 11, then when the boost fades, drop under 11. I put 11-11.9? Link to comment Share on other sites More sharing options...
Alan M Posted April 14, 2010 Report Share Posted April 14, 2010 Mine seems to start at 12, settle at 11, then when the boost fades, drop under 11. I put 11-11.9? Mine is on a progressive curve from lean at low loads to 12.1 at WOT in every gear. That was recorded on a RR. I see better AFRS on the street.

project_850 Posted April 17, 2010 Author Report Share Posted April 17, 2010 I can't seem to figure out why the hell I'm running so pig rich :( Link to comment Share on other sites More sharing options...
98 s70 t5m Posted April 17, 2010 Report Share Posted April 17, 2010 FWIW I found a minor boost leak of approx 1psi (that I only noticed up in the higher rpms, the tune was hitting 17+ in the lower rpms). It seemed to raise my afr's about 0.5. The tune I have (RICA stage 2) seems like it is setup to run 17 psi @ 12 afr, but the afrs get richer as I get up there in the RPMs and the boost fades. Also, I had good vacuum of about 20 before I found the leak. Vaccuum is just slightly better and I can barely tell on my analog guage. At some point I'm going to talk to a shop about smoke testing and see if I can find any others. Long story short, the first place I would look is a boost leak.

project_850 Posted April 17, 2010 Author Report Share Posted April 17, 2010 I draw 20 in HG too @ idle, 24HG @ decel. Pressure tested, no leaks. But I'm only running 10 psi at this point so that could be why. Gonna check the MAF tonight. Link to comment Share on other sites More sharing options...

project_850 Posted April 19, 2010 Author Report Share Posted April 19, 2010 Are you running stock ECU? Just cleaned the MAF. Running at 11's now Yes I'm running the stock 225 R ECU for now--I wanted to see how the car would react seeing as how it came from the factory with white injectors. With boost set at only 10psi, it definitely runs pig rich. Not gonna be turning it up until I receive my revised Stage III tune in the mail.
