    Default Open Loop SD VS Closed Loop SD Advantages???

    What are the advantages of going either Open Loop SD or Closed Loop SD??? Right now I just went to Closed Loop SD. I know in open loop SD you are not using the O2's. You would probally want to leave the WB in all the time??

    If you want to dial in your part throttle better, the NB's might be more accurate around stoich than the wideband. Therefore, you could tune part throttle based off of STFT's (turn LTFT's off if with in +/- 10), which is what I did. Otherwise, just go open loop with the wideband and be done with it.
