Mark,

That helps some. Because I had no idea how to disable items but I see you mention turning off items all the time and I understand the reason is to eliminate blm reading from being affected by something other than the o2 sensor, such as PE, DFCO, EGR and so on.

I may be wrong but I thought I had read in other threads where you mentioned disabling the open loop so that it cannot go into open loop while data logging. For example my chip the way it is currently tuned goes into open loop at idle, I like the way it idles in open loop better. It really isn’t issue because I have learned from David how to sort open loop out of the log using excel. But I understand if you could disable open loop how it would eliminate that step.

I thought rinse and repeat meant just clear out data and repeat but I thought I better ask to be sure.

By the way I finally ordered a burn 2 from Moates today so that I can take what I have learned to the next step and actually be able to burn my own chip.

Thanks Again
