Mods are listed in the garage. Fuel pressure read 41psi with the vacume disconnected, 34psi connected. Pump has been rewired.
Log is here from Pocketlogger http://www.elmnet.net/~lange_c/run2_4_15_05.xls Scroll up to get all the data. It's running lean, the Injectors are running near over 100% and the o2's are around .8. How ugly does it look to you guys? About how much FP should I add? I'm going to try a stock auto trans FPR or a 2g (I can't remember what you said you had Darryl...). Anybody try one of those B&M Commandflo regulators? -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???

Well I tried a fuel pressure regulator I got from a friend with the end crushed to increase the pressure. I figured I give it a try...gauge read 62psi with the vacume disconnected, 56psi connected. Seemed kind of high but I figured I do some runs since I had it mounted.
Log is here on a second gear rolling run: http://www.elmnet.net/~lange_c/run5_3_05.xls Knock is worse under a WOT run, I would think it would have gotten better. Timing for the most part stayed above 15...and shifts had a cloud of smoke seemingly indicating rich. On the good side, a 10 min dive around town game up with a 81 % Lo fuel trim which make sence with the increase pressure, but I had no more 2 counts of knock during the whole drive, where before I could get counts of 43 going up a hill. More pressure definitely helped the low end, seems to pull better with less knock. But is the pump running out of reserve starting at this high of base pressure? Can I hurt something running this high of base pressure? -------------------- 92 Eagle Talon TSI AWD "The Black Golfball" How fast can a 14B go???
