Homebrew FATS log 69F - 92 OCT - Plain K04's

Killer00S4 · 07-20-2006, 02:48 PM

90F above sea level
69F
92 craptane
RS4 IC's
Greentops.
Plain jane K04
21PSI hold.
MBC + TCD
GIAC X

I think I can use some more fuel actually. Just reduced my airflow from 280-290G/S down to 260 by going from 3.5" in front of MAF to 4"

likes 92 around 87-88 more then 86ish. IMO not bad for being that lean.

SLPR S4 · 07-20-2006, 03:24 PM

IAT's of 120 and your O2's (even though they are narrow band) seem to be right on at .86 ish.

Your car is making very good power for 21 psi. When you log, document the humidity and most importantly barometric pressure as well.

IMO, your car looks very, very good for that boost. The only thing I see is high-er CF's. If you recently changes MAF's, pull the ECU overnight, reinstall it in the morning and after the car adapts the TB on it's own, use block 060 to readjust it through VAG as well. Go to the bottom left corner of the box and hit "switch to basic settings." If you watch the 4 block 060 boxes you will see things adjusting until it says "ADP OK." It takes a matter of seconds.

The car will re-learn the fueling and air flow and CF's should go down. It may be trying to adapt from old values averaging everything old and new and getting confused. Just my opinion though through my own experience of doing the exact same thing when I went from a 83 mm to a 90 mm.

p.s. It will take 2-3 days for the car to re-adapt LTFT and idle fuel trims.

overall with 92 craptane. When Stage 2+ I played with Lemmi with AudiS4guy and found reducing timing offset in hotter temps with 91 craptane actually benefited in more power on the dyno.

less than great gas.

Propos to Anthony for the help with my A'pexi as well - uber nice guy!
