Title: Severe B1 and B2 Lambda fluctuations Post by: JK503 on September 04, 2014, 11:23:47 AM This is basically a Turbo R32. ECU number 022906032FK. It is my personal car I have been tuning.
After idling for a bit and letting idle trims adapt, then 02 readings start to go from -25 to +25 back and forth. Both front sensors are wideband and my wideband gauge reads the same. Holding the RPM at 2k it does the same fluctuations. Both sensors are in the same downpipe and if I unplug one sensor the other one still reads and functions without fluctuating. I attached a vagcom log. If I need to log anything specifically please let me know. Thanks. |
