I think Wide Band data in the data log would be very helpful. Maybe a good plan going forward would be Open Loop tuned with Wide Band in the data log?

I don't know, I am going to play with it some this weekend. For the most part the truck is running really good. I took a couple more degrees of timing out of it. I was getting a little knock at 100 KPA (no boost) no knock at all under boost that I can hear. I know when the weather warms up this thing is going to be a whole different animal. I really need to get a MAT installed as well. Also need to put the knock sensor back on. Truck has not had one for years.
I would really like to keep the thing in closed loop if at all possible, don't really see why that cant be done, its running that way now and makes fuel corrections.

Building a new motor, adding a MAT sensor and putting the knock sensor back on, but I need a V8 Memcal, mine is V6. Anybody have one?
I let a friend borrow the stock one out of my truck, was tuning for him, and his truck caught fire with my memcal in it....years ago... I have been running a V6 memcal since with knock disabled.....:mad1:
OUCH$$$
I think you should strongly consider "Tuned OPEN LOOP". The VE Table in "Tune OPEN LOOP" is adjusted the same was as an running engine closed loop. BLM's are not as accurate as AFR data. The '7427 still uses the VE tables in OPEN LOOP.
