New at this so please go easy on me!
Prior to purchasing HPT I got a chance to play with a friends EFI Live tuning software. When we did some logs of my car, when I went WOT the indicator when RED, open loop, off WOT it went GREEN, closed loop.
The only time I see RED, open loop, in the HPT Status Bits is on a cold start up. As soon as the car warms up the Status Bit goes green and stays that way no matter how many times I go WOT.
What's up?

It doesn't have to be perfect, it just needs to be done in two weeks...

you are not comparing the same things
the closed loop fuel status bit shown in your log means that basic closed loop conditions have been satisfied (ie. O2's are warm and engine is warm). It will not disable when you go wot. You can see that fuel trim learn goes to disable when you go WOT. Also if you log fuel system status in the table display you will see the status changes to open loop (this is the status that efilive uses in it's display from memory).
I count sheep in hex...
Cool. Thanks Chris, I'll do that!
