I have just installed my WB which is from www.wbo2.com the 2CO model and was very easy to install an setup onto the MPVI. However after driving around and logging my AF is .2 from my commanded AF Ratio nearly all of the time. Does anyone think this is a calibration issue or is this normal as I have not done any tuning yet? And I also have some intake mods and the tune may be out? I am about to start tuning the VE table using LTFT and STFT this may bring it all back into line. The WB requires a free air calibration so it is a bit of a pain to remove it to calibrate, how often to WB's go out of calibration? Correct me if I am wrong but they should'nt go out at all if they are always installed with power on the heater.
Thanks in advance
I can supply a log file if required to check out the log.
