N370 ecu
4 OEM 550cc cleaned and tested by witchhunter performance
3rd gen pump 36psi at idle
plugs foul every two months or so, doesn't flood, just gets hard to start until i change the plugs... they are never wet, just dark
runs rich based on my wideband 10.6 at idle, but i haven't calibrated it lately
oil smells lightly gassy, but not near as bad as smell of other 7 owners oil i've changes

10.6 at idle?! That's even too rich for full boost!

Actually my FC on stock injection (n370, cleaned 550s, perfect state of tune) ran 10.7 at idle, before switching to the PFC.

I think that if more people put widebands on their stock injected cars they would be surprised what it does and when.

I've actually take my FCON off hoping it would run less rich, but it doesn't seem to change anything. It felt alot peppier with the FCON tho.

Holy hell! Something was certainly wrong with that car. I've never seen the stock ECU run that rich at idle with a wideband. If everything is working correctly, it should be off the scale lean due to the air pump. Without emissions stuff it's typically in the high 12s/low 13s. I'm surprised you weren't fouling plugs every day with that thing.

I had absolutely no issues with the stock ecu, and again a perfect state of tune and driveability and it always idled at 10.7. In fact I milked 23mpg out of it on the way to last year's DGRR event while still on the stock ecu. IT was only fat at idle, and when lifting off the throttle 95% but not quite 100%, when it would drop into the 11's.

I did foul a 10.5 race plug that I tried when I was running 18psi on the t04e with an fcon that one time

Now with the PFC I idle around 12.5 but it idles the same.
