Paul, as long as you can monitor LTFT, when you put the pedal all the way down (100% TPS) while cruising along going say 35 mph in 3rd gear, that should cross you over from CL to OL. The LTFT should lock on to a fixed number and stop floating around. I know the actual TPS is lower than that something like 48% but going 100% will guarantee it. I still have my stock tune on my laptop that I reference with HPTuners software on occasions like this. I also have a new Aeroforce gauge that I'm still working on getting the over the steering wheel pod made so I can do monitoring, although my AFR looks fine at WOT with the new setup.
