From the factory it is set to go into open loop at 100 load @ 4000rpm, 125 load at 3500 rpm and 140 load at 2500 rpm.
If you set it all to 0 it will be in open loop all the time, etc etc.
There is also a open loop throttle volt table as well.

Bryan, thanks for sharing your extensive knowledge! Does using open loop cruise require extensive logging and tuning to get it just right? I'd personally be a little scared to do this unless I had a permanent wideband o2 installed in order to monitor afr during cruise conditions. Seems like there would be a bit of trial/error to get this just right.

Yeah definitely need a wideband to tune, but I don't think you definitely need one permanently installed. Just wanted to throw that question out there since some people will have an LC-1 or ZT-2 but no permananent gauge used to monitor afr at all times. It just seems like it might be a bit tricky to get open loop cruising fueling right unless you're an expert like Bryan. So my question is, how hard would it be to do?

Well I'm gonna have a permanent install. Why not? Gonna have AEM Oil Pressure, Boost and UEGO WB. The best tuning and monitoring tools. Why not buy a UEGO and install it permanently into your DP? Be safe and if you ever want to retune you're set.

yeah I have only gotten the secondary o2 CEL in conjunction with the 1235 overboost CEL. Funny thing is that I'm running off the factory boost control with just standard bolt ons. From what I hear though, it's easy to get these codes when you're un-tuned with bolt ons, unless I'm completely off base...??
