I included OEM tire sizes and VSS data where I could get it. The stock HF and the stock VX tire/wheel combo was almost a quarter inch shorter in diameter than the 185/60-14s you are running. So your effective gearing is notably taller than he 3.25 VX/CX.
As for lean burn, I'm not sure the gearing is the reason LB is not working at speed. But you could test it, maybe, this way.... the HX transmission was a 3.722 final drive and the same 0.702 fifth as the VX/CX. So your VX/CX fourth (0.853) will be close to the HX fifth when you factor in your tire/weel combo. Your car should be able to go into lean burn at freeway speeds in 4th, because the HX ecu will be reading the data as roughly the same as OEM HX fifth.
EDIT: The problem with LB might be about throttling. Aero improvements would reduce throttle position, seems to me, and allow lean burn, even in fifth on your VX/CX trans at 60 mph and roughly 2000 rpms, as long as everything else is woking well for LB.
Good luck!

Your theories are right about LB. 5th is on the very low end of lb's rpm requirements and the engine load is too high. 4th gear at the same speed I can get it on demand.
So far the 3 days I drove the car with this trans, when the situation comes up to stay in 5th with no LB or downshift to 4th and get lb it's always been beneficial to stay in 5th according to the mpguino.
Lower RPM > LB in all instances so far.
