Is that for all ECMs?

I don't know what the exact procedure is for WOT but have read some conversations on TGO were some of the most experianced EFI guys argue that O2 is used and some that say it is not used.

From my humble opinion I beleive you are correct but the BLM value just before WOT is used to calculate the AFR commanded before entering PE. Right? You have to enter PE at WOT.

NOTE to Greg: I left you a message on your phone. Also got your PM a day late? Now I have responded to your PM but they are stuck in my outbox not sent and I can't figure out why....
