80% accel, 75%decel, 85% secondary, -23% primary
pulling whopping 4.70 FATS times

1SeriousPig · 08-14-2005, 11:14 AM

it used to hit full at 3600, now it's at 3000 after pulling some extra fuel
it's still throwing that +dev code though

I'd spend the 5min and do a pressure test, as the midget suggested.

Mike2kS4 · 08-14-2005, 11:34 AM

If it's hot out and you're on 91 I'd classify that as "normal".

If your IC's are heat-soaked that's in the range of what I'd call "normal".

A.) Your timing sucks, even for 95F.

B.) Your airflow #s must be inflated, open up your airbox more for christ sake.

C.) Check for leaks, you should NOT have a + deviation code with X chip and TCD unless you live at some crazy high elevation.

D.) Try secondary at 100% and see how things change. I don't think it really makes much of a difference.

think i should up the secondary fuel? it's at 85% now.

Mike2kS4 · 08-14-2005, 12:23 PM

You can put secondary to 100% without any issues. I don't think it will help you at all though.

Mike2kS4 Elder Member Account #: 38083 Join Date: Jun 2002 Posts: 12,104	That timing is quite low. Log block 004 to see what kind of air you're ingesting. If it's hot out and you're on 91 I'd classify that as "normal". __________________ 2002 S4 Avant, 6spd.

Log Cyl 5 and 6 to be sure we don't have a "problem child" If your IC's are heat-soaked that's in the range of what I'd call "normal". __________________ 2002 S4 Avant, 6spd.
