1. Yup, open loop 100% of the time. Closed loop can only be enabled with feedback via O2 sensors.
2. Depends on what you're needing to change You'll still use the same tables as everyone else, you just will be in open loop.
3. It doesn't. The PCM will run off the main VE table for fueling.
I'd be interested in seeing the stock flash from your car!

Hell yeah! I want to see that tune bad. I don't suppose anybody has a copy of an export open loop tune? That would be a sweet to add to my collection. There is a lot I would like to examine in the BIN... Anybody got one for HPTuners?

I thought so, thanks guys, as soon as i get my HPT (2 weeks or so), I'll send you both my Stock bin.
As a trade off, maybe you could tip toe me through some tuning advice. I have a Wideband Commander so that should help a little.
Right now, I'm tuning Via Predator and i also tried the Vinci/Crane handheld, but I'm way rich up to trq peak and fine till HP peak.
if I lean it then it is fine down low but becomes lean on top (since it adds or lean across the board).
Also, I'm guetting KR or TM retard (fall on face) at around 4000>4200 rpm in 1st at WOT, this thing has me stumped.
No exhaust leak, no banging, 95 octane gas but this thing wont go away.
So i guess it is time for HPT.
I hope to be able to grasp this thing quickly so you guys don't think i'm a hopeless case.
i'm doing as much reading as i can, the abreviations are killing me.
