LRT released a pretty comprehensive XDF file to use with TunerPro for tuning this OS. The XDF is here http://www.gearhead-efi.com/Fuel-Inj...5&d=1547480880 Speed density can be forced by not plugging in a MAF sensor. You do need to use an IAT sensor. There are plenty of threads out there on using speed density with a 411.
The threads containing these files are here http://www.gearhead-efi.com/Fuel-Inj...rPro-Bin-Files and here http://www.gearhead-efi.com/Fuel-Inj...light=12212156 You may want to research swapping OS's on the 411 with whatever software and flash cable you plan on using and how speed density tuning works. With a stock engine, it may be easier to install the MAF and the tune will be close as is.

Hope this helps,

Thanks. Not sure how I didn't see that one. It'll be a few months before I get this engine transplanted, but I am hoping that I have an ECM that it will run with before I need to start it! I already have swapped an OS with PCM Hammer and and getting familiar with that too. I have read that I need to set a MAF setting to 0, but I need to look back at what setting that is. Thanks for the help!
