Hey guy's- I've been trying for months to make sense of this car and can't seem to isolate the issue. Setup: 110k mile motor.- New Frankenturbos, EV-14 Injectors 52lb injectors, 4bar FPR, 044 Fuel pump, new fuel filter, 85mm billet maf followed by 10 inches of pipe and open element intake, ssac fullback, haltech dual wideband. Logging- old ross tech serial, couldn't get it to work with me7 logger so I used ecu-x. I removed ignition timing info from logs due to slower baud rate. Tune- 8D0907551M - Rear 02's removed. Calculated TVUB's from PovGRide742's thread. Krkte .054, MLHFM scaled to 1426 (Tony's). KFMLDMX table raised. Results- Car idles rich (vacillates from 14.7 to 14.1), hovers around 14.5 14.6 for part throttle. When lifting off the the accelerator the wideband goes rich to about 13.6 for a few seconds,then lean (up to 19 or so). When shifting into neutral the car does the same thing (rich then lean). When trying wot car is not enriching mixture (see wot log, also note with stock tvub's & higher krkte, I get 10.6 @ wot).
Vag-com says:
Block 33 (idle)
Bank 1 +1 to 10% .600 volts down to 0.90 volts and everywhere in between. always adding fuel on bank 1
Bank 2 -1 to 10% Volts bounce from 0.110 to 670 always pulling fuel on bank 2
Block 32 (20 miles): -1.3, 3.1, -0.6, 9.4 - Note: Even with stock TVUB's, I get negative idle's and positive part throttles (have done 100+ miles).
Other: Injection time 1.70ms 3.70- 3.9 /gs load 18% 760 to 800rpm Coolant 93c.
Only CEL is misfire cylinder 3(seems to be just at idle). I have replaced coilpacks, plugs (sidefires),swappd icm's, etc. car has never bucked at WOT. I am at the end of my rope here so any advice is appreciated. Thanks.
